Databricks SQL release notes

This article lists new Databricks SQL features and improvements, along with known issues and FAQs.

Release process

Databricks releases updates to the Databricks SQL web application user interface on an ongoing basis, with all users getting the same updates rolled out over a short period of time.

In addition, Databricks typically releases new SQL warehouse compute versions regularly. Two channels are always available: Preview and Current.

Channels

Channels let you choose between the Current SQL warehouse compute version or the Preview version. Preview versions let you try out functionality before it becomes the Databricks SQL standard. Take advantage of preview versions to test your production queries and dashboards against upcoming changes.

Typically, a preview version is promoted to the current channel approximately two weeks after being released to the preview channel. Some features, such as security features, maintenance updates, and bug fixes, may be released directly to the current channel. From time to time, Databricks may promote a preview version to the current channel on a different schedule. Each new version will be announced in the following sections.

To learn how to switch an existing SQL warehouse to the preview channel, see Preview Channels. The features listed in the user interface updates sections are independent of the SQL Warehouse compute versions described in the Fixed issues section of the release notes.

September 5, 2024

Changes in 2024.40

Databricks SQL version 2024.20 includes the following behavioral changes, new features, and improvements.

Behavioral changes

• Change to the default schema binding mode for views

  Views now adapt to schema changes in the underlying query by using schema compensation with regular casting rules. This is a change from the previous default of BINDING mode, which raised errors when a safe cast could not be performed when referencing the view.

  See CREATE VIEW and cast function.

• Disallow using the undocumented ! syntax instead of NOT outside boolean expressions

  With this release, the use of ! as a synonym for NOT outside of boolean expressions is no longer allowed. For example, statements such as the following: CREATE ... IF ! EXISTS, IS ! NULL, a ! NULL column or field property, ! IN and ! BETWEEN, must be replaced with: CREATE ... IF NOT EXISTS, IS NOT NULL, a NOT NULL column or field property, NOT IN and NOT BETWEEN.

  This change ensures consistency, aligns with the SQL standard, and makes your SQL more portable.

  The boolean prefix operator ! (for example, !is_mgr or !(true AND false)) is unaffected by this change.

• Disallow undocumented column definition syntax in views

  Databricks supports CREATE VIEW with named columns and column comments. Previously, the specification of column types, NOT NULL constraints, or DEFAULT has been allowed. With this release, you can no longer use this syntax.

  This change ensures consistency, aligns with the SQL standard, and supports future enhancements.

• Adding a CHECK constraint on an invalid column now returns the UNRESOLVED_COLUMN.WITH_SUGGESTION error class

  To provide more useful error messaging, in Databricks Runtime 15.3 and above, an ALTER TABLE ADD CONSTRAINT statement that includes a CHECK constraint referencing an invalid column name returns the UNRESOLVED_COLUMN.WITH_SUGGESTION error class. Previously, an INTERNAL_ERROR was returned.

New features and improvements

• Enable UniForm Iceberg using ALTER TABLE

  You can now enable UniForm Iceberg on existing tables without rewriting data files. See Enable by altering an existing table.

• UTF-8 validation functions

  This release introduces the following functions for validating UTF-8 strings:

  • is_valid_utf8 verified whether a string is a valid UTF-8 string.
  • make_valid_utf8 converts a potentially invalid UTF-8 string to a valid UTF-8 string using substitution characters
  • validate_utf8 raises an error if the input is not a valid UTF-8 string.
  • try_validate_utf8 returns NULL if the input is not a valid UTF-8 string.

• try_url_decode function

  This release introduces the try_url_decode function, which decodes a URL-encoded string. If the string is not in the correct format, the function returns NULL instead of raising an error.

• Optionally allow the optimizer to rely on unenforced foreign key constraints

  To improve query performance, you can now specify the RELY keyword on FOREIGN KEY constraints when you CREATE or ALTER a table.

• Support for dropping the check constraints table feature

  Selective overwrites using replaceWhere now run jobs that delete data and insert new data in parallel, improving query performance and cluster utilization.

• Parallelized job runs for selective overwrites

  Selective overwrites using replaceWhere now run jobs that delete data and insert new data in parallel, improving query performance and cluster utilization.

• Improved performance for change data feed with selective overwrites

  Selective overwrites using replaceWhere on tables with change data feed no longer write separate change data files for inserted data. These operations use a hidden _change_type column present in the underlying Parquet data files to record changes without write amplification.

• Improved query latency for the COPY INTO command

  This release includes a change that improves the query latency for the COPY INTO command. This improvement is implemented by making the loading of state by the RocksDB state store asynchronous. With this change, you should see an improvement in start times for queries with large states, such as queries with a large number of already ingested files.

User interface updates

The features listed in this section are independent of the SQL Warehouse compute versions described above.

AI/BI dashboards

• The width of the Values column in pivot tables now auto-adjusts based on the width of the cell value names.
• An issue that caused the pivot table layout to break when the same field was added more than once has been resolved.
• Cross-filter highlighting now works correctly in dark mode.
• Find and replace is now supported in the SQL editor on the Data tab. Use keyboard shortcuts Command-F or Ctrl-F to open the find and replace tool.
• The time displayed in dashboard widgets now respects the timezone of the attached SQL warehouse, rather than UTC. This behavior is consistent with widgets on legacy dashboards.

Visualizations

July 11, 2024

Databricks SQL Version 2024.35 Available

Rollout Schedule: Preview rollout for 2024.35: Between July 9th and July 15th

Changes in 2024.35

Disable column mapping with drop feature

You can now use DROP FEATURE to disable column mapping on Delta tables and downgrade the table protocol. See Disable column mapping.

Variant type syntax and functions in Public Preview

Built-in Apache Spark support for working with semi-structured data as VARIANT type is now available in Spark DataFrames and SQL. See Query variant data.

Variant type support for Delta Lake in Public Preview

You can now use VARIANT to store semi-structured data in tables backed by Delta Lake. See Variant support in Delta Lake.

Support for different modes of schema evolution in views

CREATE VIEW and ALTER VIEW now allow you to set a schema binding mode, enhancing how views handle schema changes in underlying objects. This feature enables views to either tolerate or adapt to schema changes in the underlying objects. It addresses changes in the query schema resulting from modifications to object definitions.

Performance improvement for some window functions

This release includes a change that improves the performance of some Spark window functions, specifically functions that do not include an ORDER BY clause or a window_frame parameter. In these cases, the system can rewrite the query to run it using an aggregate function. This change allows the query to run faster by using partial aggregation and avoiding the overhead of running window functions. The Spark configuration parameter spark.databricks.optimizer.replaceWindowsWithAggregates.enabled controls this optimization and is set to true by default. To turn this optimization off, set spark.databricks.optimizer.replaceWindowsWithAggregates.enabled to false.

Support for the try_mod function added

This release adds support for the PySpark try_mod() function. This function supports the ANSI SQL-compatible calculation of the integer remainder by dividing two numeric values. If the divisor argument is 0, the try_mod() function returns null instead of throwing an exception. You can use the try_mod() function instead of mod or %, which throws an exception if the divisor argument is 0 and ANSI SQL is enabled.

User interface updates

AI/BI dashboards:

• Right-clicking on a dataset now shows the option Suggest name. This tool uses table metadata to automatically rename your dataset.
• You can opt to hide the legend in a visualization widget.
• Widget titles that are truncated now show the full title on hover.
• Widgets now show a truncation warning if full results are not shown.
• The Databricks Assistant for visualization authoring reverts to the original title upon rejecting a recommendation.
• Published and draft dashboard views are now captured in AI/BI dashboard audit logs with the event names: getDashboard, getPublishedDashboard, and getDashboardDetails. See Dashboards events.
• You can now set default values for Single value and Multiple values filter types. See Filter on fields.
• Fixed an issue preventing users from switching from empty pivot to the other chart types in dashboard visualization editor.
• Pivot column header text no longer overflows if it exceeds column width.

SQL Editor:

The inline assistant is now available in the SQL editor. Click the assistant icon in the editor box to toggle the input. Type a question or comment in English, then press Enter (not Shift+Enter, which runs a query) to generate a response with a different view directly in the editor.

Platform:

An API for notification destinations is now available. You can now programmatically manage webhook and email destinations for your alerts and job run notifications. See Notification Destinations.

DESCRIBE HISTORY now shows clustering columns for tables that use liquid clustering

When you run a DESCRIBE HISTORY query, the operationParameters column shows a clusterBy field by default for CREATE OR REPLACE and OPTIMIZE operations. For a Delta table that uses liquid clustering, the clusterBy field is populated with the table's clustering columns. If the table does not use liquid clustering, the field is empty.

Support for primary and foreign keys is generally available

Support for primary and foreign keys in Databricks Runtime is generally available. The GA release includes the following changes to the privileges required to use primary and foreign keys:

• To define a foreign key, you must have the SELECT privilege on the table with the primary key that the foreign key refers to. You do not need to own the table with the primary key, which was previously required.
• Dropping a primary key using the CASCADE clause does not require privileges on the tables that define foreign keys that reference the primary key. Previously, you needed to own the referencing tables.
• Dropping a table that includes constraints now requires the same privileges as dropping tables that do not include constraints.

To learn how to use primary and foreign keys with tables or views, see CONSTRAINT clause, ADD CONSTRAINT clause, and DROP CONSTRAINT clause.

Liquid clustering is GA

Support for liquid clustering is now generally available using Databricks Runtime 15.2 and above. See Use liquid clustering for Delta tables.

Type widening is in Public Preview

You can now enable type widening on tables backed by Delta Lake. Tables with type widening enabled allow changing the type of columns to a wider data type without rewriting underlying data files. See Type widening.

Schema evolution clause added to SQL merge syntax

You can now add the WITH SCHEMA EVOLUTION clause to a SQL merge statement to enable schema evolution for the operation. See Schema evolution syntax for merge.

Vacuum inventory support

You can now specify an inventory of files to consider when running the VACUUM command on a Delta table. See the OSS Delta docs.

Support for Zstandard compression functions

You can now use the zst_compress, zstd_decompress, and try_zstd_decompress functions to compress and decompress BINARY data.

Query plans in the SQL UI now correctly display PhotonWriteStage

When displayed in the SQL UI, write commands in query plans incorrectly showed PhotonWriteStage as an operator. With this release, the UI is updated to show PhotonWriteStage as a stage. This is a UI change only and does not affect how queries are run.

• Visualizations
  • Introducing a new, modern color palette for visualizations and dashboards. To change a dashboard to the new color palette, go to your dashboard, click on Edit -> Colors -> Import and select the Databricks Color Palette. SQL Admins can also set the new color palette as the default option for a workspace by going to Settings -> QL Admin Console -> Workspace Colors -> Import and selecting the new palette.

Fixes:

• Fixed an issue where previously selecting Apply Changes to apply a filter did not work if a query was already being executed.

August 4, 2022

Improvements:

• On cloning a dashboard, there is now an option for whether or not queries should be cloned as well.
• Tab content is synced across browser tabs. The state of your query will now be in sync across all browser tabs. This means that if you are working on query1 in browser tab 1 and then switch to browser tab 2, you'll see query1 in the state you left it in while in the original browser tab.

Fix:

• Labels for empty strings in pie chart now reflect that the string is empty rather than the index of the value.

July 28, 2022

• Alerts
  • Custom alert email templates have been updated to disallow certain HTML tags that may pose a security risk. Disallowed HTML tags and attributes are automatically sanitized. For example, is a disallowed HTML tag, so instead of rendering a button, the text "button" displays. See Alerts for the list of allowed HTML tags and attributes.
  • Users can now subscribe other users to alerts without needing to create a notification destination, which requires admin permissions.
• Downloads: Users can now download up to approximately 1GB of results data from Databricks SQL in CSV and TSV format, up from 64,000 rows previously.
• Visualizations
  • You can now edit visualizations directly on the dashboard. In edit mode, click on the kebab menu and select Edit visualization to begin editing the visualization.
  • When downloading results associated with a visualization leveraging aggregations, the downloaded results are also aggregated. The option to download is moving from bottom kebab to the kebab associated with the tab. The downloaded results are from the most recent execution of the query that created the visualization.
• SQL editor: Results tables now display a message when data displayed by the in-browser table has been limited to 64,000 rows. TSV and CSV download will still be up to approximately 1GB of data.
• Query filters:
  • Query filters have been updated to work dynamically on either client- or server-side to optimize performance. Previous query filters (now legacy) operated client-side only. Users can still use legacy filters with the :: syntax, if desired.
  • The updated filters are simpler: Users click a +Add Filter button and select a column from a dropdown. Previously, users had to modify the query text directly.
  • Relevant values are highlighted to make it easier to see which selections within a filter will return results given other filter selections.
• Query history: Query details in Query History now show the Query Source, which is the origin of the executed query.

July 21, 2022

• Notifications on share: Users will now be notified by email whenever a dashboard, query, or alert is shared with them.
• Enhanced SQL editor experience via the new embedded editor toolkit
  • Live syntax error highlighting (for example, wrong keyword, table does not exist, and suggestions for fixing the error)
  • In context help: on hover (for example, full table name, detailed Function panel) and inline execution error messages (for example, highlight row with error post execution)
  • Intelligent ranking of suggestions (for example, parameter autocompletion, ranking formula, less noisy matching)

July 14, 2022

• You can now upload TSV files using the Create Table UI in addition to CSV files.
• Databricks SQL now provides the option to notify users by email whenever a dashboard, query, or alert is shared with them.
• Visualization tables now optionally include row numbers displayed next to results.
• When you select a geographic region for the Chloropleth visualization, you now get inline hints for accepted values.

June 23, 2022

• SQL endpoint name change: Databricks changed the name from SQL endpoint to SQL warehouse because it is more than just an API entry point for running SQL commands. A SQL warehouse is a computation resource for all your data warehousing needs, an integral part of the Databricks platform. Compute resources are infrastructure resources that provide processing capabilities in the cloud.
• For Choropleth visualizations, the Key column and Target field selections in the visualization editor have been renamed to Geographic Column and Geographic Type. This renaming for understandability does not introduce any behavior changes to new or existing Choropleths.
• The limit 1000 query option has moved from a checkbox in the SQL query editor to a checkbox in the run button.
• Cached queries in Query History table are now marked with a Cache tag.
• Manually refreshing a dashboard uses the dashboard's warehouse (if available) instead of each individual query's warehouse.
• Refreshing an alert always uses the alert's warehouse, regardless of the Run as Viewer/Owner setting.

June 9, 2022

• When you hover in the endpoint selector, the full endpoint name is displayed as a tooltip.
• When you filter in the SQL editor schema browser, the search term is now highlighted in the search results.

• To reopen the last closed tab in the SQL editor, use this new keyboard shortcut: <Cmd> + <Shift> + <Option> + T
• You can now add data labels to combination charts.
• The list of visualization aggregations operations now includes variance and standard deviation.

May 26, 2022

Authoring improvements:

• You can now bypass aggregations when you author visualizations. This is particularly useful when your query already includes an aggregation. For example, if your query is SELECT AVG(price_per_sqft), isStudio, location GROUP BY location, isStudio, the chart editor previously required explicitly specifying another layer of aggregation.
• When you author dashboards, you now have the ability to:
  • Duplicate textbox widgets
  • Expand the size of the edit textbox panel
• The default aggregation for the error column when you author visualizations is standard deviation.

Fixes:

• Edit actions for visualizations are only available when the dashboard is in edit mode. Edit actions are no longer available as a view mode action.
• When you create a new query, it opens in a tab to the immediate right of the tab in focus rather than at the end of the list.
• The open query modal shows which query is already open and provides the option to switch focus to that query tab.
• The Sankey & Sunburst charts no longer treat 0 as null.

May 19, 2022

• Fixed issue: When you have the focus of the SQL editor open on a specific visualization tab and share the link to another user, the user will have the same focus in the SQL editor when they click the shared link.
• Improvements:
  • Microsoft Teams is now a supported notification destination.
  • The Date Range, Date and Time Range, and Date and Time Range (with seconds) parameters now support the option to designate the starting day of the week, with Sunday as the default.

May 12, 2022

• Visualizations now support time binning directly in the UI. You can now easily switch between yearly, monthly, daily, or hourly bins of your data by changing a dropdown value rather than adding and modifying a date_trunc() function in the query text itself.
• Dashboards now have color consistency by default. If you have the same series across multiple charts, the series is always colored the same across all charts - without requiring any manual configuration.

May 3, 2022

• When sharing a dashboard with a user or group, we now also provide the ability to share all upstream queries used by visualizations and parameters.
  • When you do not have permission to share one or more of the upstream queries, you will receive a warning message that not all queries could be shared.
  • The permissions granted when sharing a dashboard do not override, negate, or expand upon existing permissions on the upstream queries. For example, if a user or group has CAN RUN as Owner permissions on the shared dashboard but only has Run as Viewer permissions on an upstream query, the effective permissions on that upstream query will be Run as Viewer.

April 27, 2022

• Your dashboard layout is now retained when exporting to PDF on demand and generating scheduled subscription emails.

March 17, 2022

• Charts includes a new combination visualization option. This allows you to create charts that include both bars and lines.

March 10, 2022

• Unity Catalog (Preview) allows you to manage governance and access to your data at the level of the account. You can manage metastores and data permissions centrally, and you can assign a metastore to multiple workspaces in your account. You can manage and interact with Unity Catalog data and objects using the Databricks SQL Catalog Explorer or the SQL editor, and you can use Unity Catalog data in dashboards and visualizations. See What is Unity Catalog?.

• Delta Sharing (Preview) allows you to share read-only data with recipients outside your organization. Databricks SQL supports querying Delta Sharing data and using it in visualizations and dashboards.
• Each time a dashboard is refreshed manually or on a schedule, all queries in the dashboard and upstream, including those used by parameters, are refreshed. When an individual visualization is refreshed, all upstream queries, including those used by parameters, are refreshed.

March 3, 2022

• The cohort visualization has been updated such that cohorts are interpolated from min and max values rather than 0 and 100. It's now much easier to distinguish cohorts within the actual range of data available. Previously, if all numbers were close together, they used the same color. Now, numbers that are close together are more likely to use different colors because the cohort is divided from the max to min range to form each series.
• It's easier to see whether a dashboard subscription schedule is active or paused. When you click Subscribe, if the dashboard subscription schedule is paused, the message This schedule has been paused appears. When a dashboard subscription schedule is paused, you can subscribe or unsubscribe from the dashboard, but scheduled snapshots are not sent and the dashboard's visualizations are not updated.
• When you view Query History, you can now sort the list by duration. By default, queries are sorted by start time.

February 24, 2022

• In Catalog Explorer, you can now view the permissions users or groups have on a table, view, schema, or catalog. Click the object, then click Permissions and use the new filter box.

February 17, 2022

• Visualizations just became a little smarter! When a query results in one or two columns, a recommended visualization type is automatically selected.
• You can now create histograms to visualize the frequency that each value occurs within a dataset and to understand whether a dataset has values that are clustered around a small number of ranges or are more spread out.
• In both Query History and Query Profile, you can now expand to full width the query string and the error message of a failed query. This makes it easier to analyse query plans and to troubleshoot failed queries.
• In bar, line, area, pie, and heatmap visualizations, you can now perform aggregation directly in the visualization configuration UI, without the need to modify the query itself. When leveraging these new capabilities, the aggregation is performed over the entire data set, rather than being limited to the first 64,000 rows. When editing a visualization created prior to this release, you will see a message that says This visualization uses an old configuration. New visualizations support aggregating data directly within the editor. If you want to leverage the new capabilities, you must re-create the visualization. See Enable aggregation in a visualization.

February 10, 2022

• You can now set a custom color palette for a dashboard. All visualizations that appear in that dashboard will use the specified palette. Setting a custom palette does not affect how a visualization appears in other dashboards or the SQL editor.

  You can specify hex values for a palette or import colors from another palette, whether provided by Databricks or created by a workspace admin.

  When a palette is applied to a dashboard, all visualizations displayed in that dashboard will use the selected color palette by default, even if you configure custom colors when you create the visualization. To override this behavior, see Customize colors for a visualization.

• Workspace admins can now create a custom color palette using the admin console. After the custom color palette is created, it can be used in new and existing dashboards. To use a custom color palette for a dashboard or to customize it, you can edit dashboard settings.

• When you add a visualization that uses parameters to a dashboard from the SQL menu, the visualization now uses dashboard-level parameters by default. This matches the behavior when you add a widget using the Add Visualization button in a dashboard.

• When you view the query history and filter the list by a combination of parameters, the number of matching queries is now displayed.

• In visualizations, an issue was fixed where the Y-axis range could not be adjusted to specific values.

February 3, 2022

• The tabbed SQL editor is now enabled by default for all users. For more information or to disable the tabbed editor, see Edit multiple queries.

• Dashboard email subscribers now receive an inline image showing the dashboard snapshot, instead of an attachment. A PDF of the snapshot is attached to the email.

• You can now balance reliability and costs by configuring the spot instance policy for SQL endpoints. The spot instance policy determines whether workers use only on-demand instances or a combination of on-demand and spot instances. Cost Optimized (the default) uses mostly spot instances and one on-demand instance. Reliability Optimized uses only on-demand instances. Previously, on-demand instances were always used for SQL endpoints. To retain this behavior, set the spot instance policy to Reliability Optimized. See Configure spot instance policy.

January 27, 2022

• Improvements have been made to how you can view, share, and import a query's profile. See Query profile.

• The Details visualization now allows you to rename columns just like the Table visualization.

• You can now close a tab in the SQL editor by middle-clicking it.

• The following Keyboard shortcuts have been added to the tabbed SQL editor:

  • Close all tabs: Cmd+Option+Shift+A (macOS) / Ctrl+Option+Shift+A (Windows)
  • Close other tabs: Cmd+Option+Shift+W (macOS) / Ctrl+Option+Shift+W (Windows)

  These keyboard shortcuts provide an alternative to right-clicking on a tab to access the same actions. To view all keyboard shortcuts, click the Keyboard icon in the tabbed SQL editor.

January 20, 2022

• The default formatting for integer and float data types in tables has been updated to not include commas. This means that by default, values like 10002343 will no longer have commas. To format these types to display with commas, click Edit Visualization, expand the area for the column, and modify the format to include a comma.
• To better align with browser rendering limits, visualizations now display a maximum of 10,000 data points. For example, a scatterplot will display a maximum of 10,000 dots. If the number of data points has been limited, a warning is displayed.

January 13, 2022

• We fixed an issue where the Save button in the SQL editor was sometimes disabled. The Save button is is now always enabled, and includes an asterisk (*) when unsaved changes are detected.

December 15, 2021

• Databricks SQL is Generally Available. This marks a major milestone in providing you with the first lakehouse platform that unifies data, AI, and BI workloads in one place. With GA, you can expect the highest level of stability, support, and enterprise-readiness from Databricks for mission-critical workloads. Read the GA announcement blog to learn more.
• Alerts are now scheduled independently of queries. When you create a new alert and create a query, you are prompted to also create a schedule for the alert. If you had an existing alert, we've duplicated the schedule from the original query. This change also allows you to set alerts for both Run as Owner and Run as Viewer queries. Run as Owner queries run on the designated alert schedule with the query owner's credential. Run as Viewer queries run on the designated alert schedule with the alert creator's credential. See What are Databricks SQL alerts? and Schedule a query.
• You can now re-order parameters in both the SQL editor and in dashboards.
• The documentation for creating heatmap visualizations has been expanded. See Heatmap options.

December 9, 2021

• When you create a table visualization, you can now set the font color for a column to a static value or a range of values based on the column's field's values. The literal value is compared to the threshold. For example, to colorize results whose values exceed 500000, create the threshold > 500000, rather than > 500,000. See Conditionally format column colors.
• Icons in the tabbed SQL editor schema browser now allow you to distinguish between tables and views.

December 1,2021

• You can now apply SQL configuration parameters at the workspace level. Those parameters automatically apply to all existing and new SQL endpoints in the workspace. See Configure SQL parameters.

November 18, 2021

• When you view a query's history, you can now filter queries on the service principal that ran them. See View query history.

• You can now open the SQL editor by using a sidebar shortcut. To open the SQL editor, click SQL Editor.

• If you have permission to create Data Science & Engineering clusters, you can now create SQL endpoints by clicking Create in the sidebar and clicking SQL Endpoint.

• Administrators can now transfer ownership of a query, dashboard, or alert to a different user via the UI. See:

  • Transfer ownership of a query
  • Transfer ownership of a legacy dashboard
  • Transfer ownership of an alert

November 4, 2021

• In a Map (Choropleth) visualization visualization, the maximum number of gradient steps for colors in the legend has been increased from 11 to 20. The default is 5 gradient steps inclusive of Min color and Max color.
• The tabbed SQL editor now supports bulk tab management. If you right-click on a tab, you'll see the option to Close others, Close left, Close right, and Close all. Note that if you right-click on the first or last tab, you won't see the options to Close left or Close right.

October 28, 2021

• When you view a table in Catalog Explorer, you have two options to simplify interacting with the table:
  • Click Create > Query to create a query that selects all columns and returns the first 1000 rows.
  • Click Create > Quick Dashboard to open a configuration page where you can select columns of interest and create a dashboard and supporting queries that provide some basic information using those columns and showcase dashboard-level parameters and other capabilities.

October 19, 2021

• New keyboard shortcuts are now available in the tabbed editor:
  • Open new tab:
    • Windows: Cmd+Alt+T
    • Mac: Cmd+Option+T
  • Close current tab
    • Windows: Cmd+Alt+W
    • Mac: Cmd+Option+W
  • Open query dialog
    • Windows: Cmd+Alt+O
    • Mac: Cmd+Option+O

September 23, 2021

• You can now create a new dashboard by cloning an existing dashboard, as long as you have the CAN RUN, CAN EDIT and CAN MANAGE permission on the dashboard and all upstream queries. See Clone a legacy dashboard.
• You can now use GROUP BY in a visualization with multiple Y-axis columns. See Scatter chart.
• You can now use {{ @@yPercent}} to format data labels in an unnormalized stacked bar chart. See Bar chart.
• If you use SAML authentication and your SAML credential will expire within a few minutes, you are now proactively prompted to log in again before executing a query or refreshing a dashboard. This helps to prevent disruption due to a credential that expires during query execution.

September 20, 2021

• You can now transfer ownership of dashboards, queries, and alerts using the Permissions REST API. See Query ACLs.

September 16, 2021

• In query results, BIGINT results are now serialized as strings when greater than 9007199254740991. This fixes a problem where BIGINT results could be truncated in query results. Other integer results are still serialized as numbers. Number formatting on axis labels and tooltips does not apply to BIGINT results that are serialized as strings. For more information about data types in Databricks SQL, see BIGINT type.

September 7, 2021

Databricks is rolling out the changes that follow over the course of a week. Your workspace may not be enabled for these changes until after September 7.

• Databricks SQL is now in Public Preview and enabled for all users in new workspaces.

  Note

  If your workspace was enabled for Databricks SQL during the Public Preview—that is, before the week beginning September 7, 2021—users retain the entitlement assigned before that date, unless you change it. In other words, if a user did not have access to Databricks SQL during the Public Preview, they will not have it now unless an administrator gives it to them.

• Administrators can manage which users have access to Databricks SQL by assigning the Databricks SQL access entitlement (databricks-sql-access in the API) to users or groups. By default, new users have this entitlement.

  Administrators can limit a user or group to accessing only Databricks SQL and prevent them from accessing Data Science & Engineering or Databricks Mosaic AI by removing the Workspace Access entitlement (workspace-access in the API) from the user or group. By default, new users have this entitlement.

  Important

  To log in and access Azure Databricks, a user must have either the Databricks SQL access or Workspace access entitlement (or both).

• A small classic SQL endpoint called Starter Endpoint is pre-configured on all workspaces, so you can get started creating dashboards, visualizations, and queries right away. To handle more complex workloads, you can easily increase its size (to reduce latency) or the number of underlying clusters (to handle more concurrent users). To manage costs, the starter endpoint is configured to terminate after 120 minutes idle.

• To help you get up and running quickly, a new guided onboarding experience is available for administrators and users. The onboarding panel is visible by default, and you can always see how many onboarding tasks are left in the sidebar. Click tasks left to reopen the onboarding panel.

• You can get started using Databricks SQL quickly with two rich datasets in a read-only catalog called SAMPLES, which is available from all workspaces. When you learn about Databricks SQL, you can use these schemas to create queries, visualizations, and dashboards. No configuration is required, and all users have access to these schemas.

  • The nyctaxi schema contains taxi trip data in the trips table.
  • The tpch schema contains retail revenue and supply chain data in the following tables:
    • customer
    • lineitem
    • nation
    • orders
    • part
    • partsupp
    • region
    • supplier

  Click Run your first query in the onboarding panel to generate a new query of the nyctaxi schema.

• To learn about visualizing data in Databricks SQL with no configuration required, you can import dashboards from the Dashboard Samples Gallery. These dashboards are powered by the datasets in the SAMPLES catalog.

  To view the Dashboard Samples Gallery, click Import sample dashboard in the onboarding panel.

• You can now create and drop native SQL functions using the CREATE FUNCTION and DROP FUNCTION commands.

September 2, 2021

• Users with the CAN EDIT permission on a dashboard can now manage the dashboard's refresh schedule and subscription list. Previously, the CAN MANAGE permission was required. For more information, see Automatically refresh a dashboard.

• By default, visualizations no longer dynamically resize based on the number of results returned, but maintain the same height regardless of the number of results. To return to the previous behavior and configure a visualization to dynamically resize, enable Dynamically resize panel height in the visualization's settings in the dashboard. For more information, see Table options.

• If you have access to more than one workspace in the same account, you can switch workspaces from within Databricks SQL. Click in the lower left corner of your Azure Databricks workspace, then select a workspace to switch to it.

August 12, 2021

• An administrator can now terminate another user's query while it is executing. For more information, see Terminate an executing query.

August 05, 2021

• Improved EXPLAIN result formatting
  • Explain results are easier to read
  • Formatted as monospaced with no line wrap

July 29, 2021

• Juggling multiple queries just got easier with support for multiple tabs in the query editor. To use the tabbed editor, see Edit multiple queries.

July 08, 2021

• Visualization widgets in dashboards now have titles and descriptions so that you can tailor the title and description of visualizations used in multiple dashboards to the dashboard itself.
• The sidebar has been updated for improved visibility and navigation:
  • Warehouses are now SQL Endpoints and History is renamed to Query History.
  • Account settings (formerly named Users) have been moved to Account. When you select Account you can change the Azure Databricks workspace and log out.
  • User settings have been moved to Settings and have been split into Settings and SQL Admin Console. SQL Admin Console is visible only to admins.
  • The help icon changed to Help.

July 01, 2021

• The new Catalog Explorer allows you to easily explore and manage permissions on databases and tables. Users can view schema details, preview sample data, and see table details and properties. Administrators can view and change data object owners, and data object owners can grant and revoke permissions. For details, see What is Catalog Explorer?.
• Y-axes in horizontal charts have been updated to reflect the same ordering as in tables. If you have previously selected reverse ordering, you can use the Reverse Order toggle on the Y-axis tab to reverse the new ordering.

June 23, 2021

• Easily configure SQL endpoints with service principals. There is now a control that helps you configure a service principal in the global SQL endpoints setting. See Configure a service principal.
• Temp views are now supported.

June 17, 2021

• Photon, Databricks' new vectorized execution engine, is now on by default for newly created SQL endpoints (both UI and REST API). Photon transparently speeds up
  • Writes to Parquet and Delta tables.
  • Many SQL queries. See Limitations.
• Easily manage users and groups with CREATE GROUP, DROP GROUP, ALTER GROUP, SHOW GROUPS, and SHOW USERS commands. For details, see Security statements and Show statements.
• The query editor schema browser is snappier and faster on schemas with more than 100 tables. On such schemas, the schema browser will not load all columns automatically; the list of tables still shows as usual, but columns load only when you click a table. This change affects query autocomplete in the query editor, because it depends on this information to show suggestions. Until you expand a table and load its columns, those suggestions are not available.

June 03, 2021

• Admins of newly enabled Azure Databricks workspaces now receive the Databricks SQL entitlement by default and are no longer required to give themselves the Databricks SQL access entitlement using the admin console.
• Photon is now in public preview and enabled by default for new SQL endpoints.
• Multi-cluster load balancing is now in public preview.
• You can now enable collaboration on dashboards and queries with other members of your organization using CAN EDIT permission. See Access control lists.

May 26, 2021

• SQL Analytics is renamed to Databricks SQL. This change has the following customer-facing impacts:

  • References in the web UI have been updated.

  • The entitlement to grant access to Databricks SQL has been renamed:

    • UI: Databricks SQL access (previously SQL Analytics access)
    • SCIM API: databricks-sql-access (previously sql-analytics-access)

    Users, groups, and service principals with the previous entitlement have been migrated to the new entitlement.

  • Tags for audit log events related to Databricks SQL have changed:

    • The prefix for Databricks SQL events is now databrickssql.
    • changeSqlAnalyticsAcl is now changeDatabricksSqlAcl.
• Dashboard updates
  • The dashboard export filename has been updated to be the name of the dashboard + timestamp, rather than a UUID.
  • The export records limit has been raised from 22k to 64k.

May 20, 2021

• You can now use your own key from Azure Key Vault to encrypt the Databricks SQL queries and query history stored in Azure Databricks. If you've already configured your own key for a workspace to encrypt data for managed services (notebooks and secrets), then no further action is required. The same customer-managed key for managed services now also encrypts the Databricks SQL queries and query history. See Customer-managed keys for managed services. This change affects only new data that is stored at rest. Databricks SQL queries and query history that were stored before today are not guaranteed to be encrypted with this key.

  Databricks SQL query results are stored in your root Azure Blob storage instance that Azure Databricks created during workspace setup, and they are not encrypted by your managed services key. However, you can use your own key to encrypt them. See Customer-managed keys for DBFS root.

  This feature is available with the Premium plan.

• The Past executions tab now shows relative time.

May 13, 2021

• Databricks SQL no longer tries to guess column types. Previously, a column with the format xxxx-yy-dd was automatically treated as a date, even if it was an identification code. Now that column is no longer automatically treated as a date. You must specify that in the query if so desired. This change may cause some visualizations that relied on the previous behavior to no longer work. In this release, you can change > Settings > Backwards Compatibility option to return to the previous behavior. In a future release we will remove that capability.

• The query editor now has a query progress indicator. State changes are now visible in a continually updated progress bar.

  

May 06, 2021

• You can now download the contents of the dashboard as a PDF. See Download as PDF.
• An admin user now has view access to all the queries and dashboards. In this view an admin can view and delete any query or dashboard. However, the admin can't edit the query or dashboard if it is not shared with the admin. See Query admin view and legacy dashboard admin view.
• The ability to increase endpoint concurrency with multi-cluster load balancing is now available for all accounts. You can create endpoints that autoscale between specified minimum and maximum cluster counts. Overloaded endpoints will scale up and underloaded endpoints will scale down.

April 29, 2021

• Query options and details are now organized in a set of tabs to the left of the query editor:

  • Data sources: Select from available data sources and schema. See Create a query.

    

  • Past executions: View past executions performed in the SQL editor. This does not show scheduled executions. See Write queries and explore data in the SQL Editor.

    

  • Query info: Set the query description, view information about the query, and set the refresh schedule. See Write queries and explore data in the SQL Editor and Schedule a query.

    

April 22, 2021

• Fixed an issue in which endpoints were inaccessible and appeared to be deleted due to internal error.

April 16, 2021

Databricks SQL maintains compatibility with Apache Spark SQL semantics. This release updates the semantics to match those of Apache Spark 3.1. Previously Databricks SQL was aligned to Apache Spark 3.0 semantics.

• Statistical aggregation functions, including std, stddev, stddev_samp, variance, var_samp, skewness, kurtosis, covar_samp, and corr, return NULL instead of Double.NaN when DivideByZero occurs during expression evaluation, for example, when stddev_samp applied on a single element set. Prior to this release, it would return Double.NaN.
• grouping_id() returns long values. Prior to this release, this function returned int values.
• The query plan explain results is now formatted.
• from_unixtime, unix_timestamp,to_unix_timestamp, to_timestamp, and to_date will fail if the specified datetime pattern is invalid. Prior to this release, they returned NULL.
• The Parquet, ORC, Avro, and JSON data sources throw the exception org.apache.spark.sql.AnalysisException: "Found duplicate column(s) in the data schema in read if they detect duplicate names in top-level columns as well in nested structures."
• Structs and maps are wrapped by the {} brackets in casting them to strings. For instance, the show() action and the CAST expression use such brackets.Prior to this release, the d brackets were used for the same purpose.
• NULL elements of structures, arrays and maps are converted to "null" in casting them to strings. Prior to this release, NULL elements were converted to empty strings.
• The sum of decimal type column overflows returns null. Prior to this release, in the case, the sum of decimal type column may return null or incorrect result, or even fails at runtime (depending on the actual query plan execution).
• IllegalArgumentException is returned for the incomplete interval literals, for example, INTERVAL '1', INTERVAL '1 DAY 2', which are invalid. Prior to this release, these literals result in NULLs.
• Loading and saving of timestamps from and to Parquet files fails if the timestamps are before 1900-01-01 00:00:00Z, and loaded (saved) as the INT96 type. Prior to this release, the actions don't fail but might lead to shifting of the input timestamps due to rebasing from/to Julian to/from Proleptic Gregorian calendar.
• The schema_of_json and schema_of_csv functions return the schema in the SQL format in which field names are quoted. Prior to this release, the function returns a catalog string without field quoting and in lower case.
• CHAR,CHARACTER, and VARCHAR types are supported in table schema. Table scan and insertion respects the char/varchar semantic. If char/varchar is used in places other than table schema, an exception is thrown (CAST is an exception that simply treats char/varchar as string like before).
• The following exceptions are thrown for tables from Hive external catalog:
  • ALTER TABLE .. ADD PARTITION throws PartitionsAlreadyExistException if new partition exists already.
  • ALTER TABLE .. DROP PARTITION throws NoSuchPartitionsException for not existing partitions.

April 13, 2021

• Improved query throughput with SQL endpoint queuing. Queries submitted to a SQL endpoint now queue when the endpoint is already saturated with running queries. This improves query throughput by not overloading the endpoint with requests. You can view the improved performance in the endpoint monitoring screen.

April 01, 2021

• Quickly find the time spent in compilation, execution, and result fetching for a query in Query History. See Query profile. Previously this information was only available by clicking a query and opening the Execution Details tab.
• SQL endpoints no longer scale beyond the maximum specified clusters. All clusters allocated to a SQL endpoint are recycled after 24 hours, which can create a brief window in which there is one additional cluster.

March 18, 2021

• Autocomplete in the query editor now supports Databricks SQL syntax and is context and alias aware. See Create a query.
• JDBC and ODBC requests no longer fail with invalid session errors after the session times out on the server. BI clients are now able to seamlessly recover when session timeouts occur.

March 11, 2021

• Administrators and users in workspaces newly enabled for Databricks SQL no longer automatically have access to Databricks SQL. To enable access to Databricks SQL, the administrator must:
  1. Go to the admin settings page.
  2. Click the Users tab.
  3. In the row for their account, click the Databricks SQL access checkbox.
  4. Click Confirm.
  5. Repeat steps 3 and 4 to grant users access to Databricks SQL or grant access to groups.
• Easily create queries, dashboards, and alerts by selecting New > [Query | Dashboard | Alert] at the top of the sidebar.
• Query Editor now saves drafts, and you can revert to a saved query. See Write queries and explore data in the SQL Editor.
• You can no longer create external data sources.
• The reliability of the SQL endpoint monitoring chart has been improved. The chart no longer intermittently shows spurious error messages.

March 04, 2021

• The Queries, Dashboards, and Alerts API documentation is now available. See Databricks REST API reference.
• Scheduled dashboard refreshes are now always performed. The refreshes are performed in the web application, so you no longer need to keep the dashboard open in a browser. See Automatically refresh a dashboard.
• New SQL endpoints created using the SQL Warehouse API now have Auto Stop enabled with a default timeout of two hours.
• Tableau Online users can now connect to SQL endpoints. See the new Tableau Online quickstart.

February 26, 2021

The new Power BI connector for Azure Databricks, released in public preview in September 2020, is now GA. It provides:

• Simple connection configuration: the new Power BI Azure Databricks connector is integrated into Power BI, and you configure it using a simple dialog with a couple of clicks.
• Authentication based on Microsoft Entra ID credentials—no more need for administrators to configure PAT tokens.
• Faster imports and optimized metadata calls, thanks to the new Azure Databricks ODBC driver, which comes with significant performance improvements.
• Access to Azure Databricks data through Power BI respects Azure Databricks table access control and Azure storage account permissions associated with your Microsoft Entra ID identity.

For more information, see Connect Power BI to Azure Databricks.

February 25, 2021

• Setting permissions on a SQL endpoint is now faster. It's a step right after you create a new SQL endpoint and easily accessible when you edit an existing endpoint. See Connect to a SQL warehouse and Manage a SQL warehouse.
• To reuse visualization settings you can now duplicate a visualization. See Clone a visualization.
• Query results are now stored in your account instead of the Azure Databricks account.
• To prevent leaking information by listing all defined permissions on an object, to run SHOW GRANTS [<user>] <object> you must be either:
  • A Databricks SQL administrator or the owner of <object>.
  • The user specified in [<user>].

January 07, 2021

• To reduce spending on idle endpoints, new SQL endpoints now have Auto Stop enabled with a default timeout of two hours. After the timeout is reached, the endpoint is stopped. You can edit the timeout period or disable Auto Stop at any time.
• Except for TEXT type query parameters, quotation marks are no longer added to query parameters. If you have used Dropdown List, Query Based Dropdown List, or any Date type query parameters, you must add quotation marks in order for the query to work. For example, if your query is SELECT {{ d }}, now this query must be SELECT '{{ d }}'.

November 18, 2020

Databricks is pleased to introduce the Public Preview of Databricks SQL, an intuitive environment for running ad-hoc queries and creating dashboards on data stored in your data lake. Databricks SQL empowers your organization to operate a multi-cloud lakehouse architecture that provides data warehousing performance with data lake economics. Databricks SQL:

• Integrates with the BI tools you use today, like Tableau and Microsoft Power BI, to query the most complete and recent data in your data lake.
• Complements existing BI tools with a SQL-native interface that allows data analysts and data scientists to query data lake data directly within Azure Databricks.
• Enables you to share query insights through rich visualizations and drag-and-drop dashboards with automatic alerting for important data changes.
• Uses Connect to a SQL warehouse to bring reliability, quality, scale, security, and performance to your data lake, so you can run traditional analytics workloads using your most recent and complete data.
• Introduces the USAGE privilege to simplify data access administration. In order to use an object in a schema, you must be granted the USAGE privilege on that schema in addition to any privileges you need to perform the action. The USAGE privilege can be granted to schemas or to the catalog. For workspaces that already use table access control, the USAGE privilege is granted automatically to the users group on the root CATALOG. See Hive metastore privileges and securable objects (legacy) for details.

See the What is data warehousing on Azure Databricks? for details.

Fixed issues

• SQL editor. The SQL editor will now persist selected text and scroll position when switching between query tabs.
• SQL editor. If you click 'Run' on a query in the SQL editor, then navigate to another page and return while the query is still executing, the editor will display the correct query state. If the query completes while you are on another page, query results will be available on return to the SQL editor page.
• You can now use MySQL 8.0 as an external metastore.
• DESCRIBE DETAIL commands on Delta tables no longer fail with java.lang.ClassCastException: java.sql.Timestamp cannot be cast to java.time.Instant.
• Reading Parquet files with INT96 timestamps no longer fails.
• When a user has CAN RUN permission on a query and runs it, if the query was created by another user, the query history displays the runner of the query as the user.
• Null values are now ignored when rendering a chart, improving the usability of charts. For example, previously, bars in a bar chart would look very small when null values were present. Now the axes are set based on non-null values only.

Known issues

• Reads from data sources other than Delta Lake in multi-cluster load balanced SQL endpoints can be inconsistent.
• Delta tables accessed in Databricks SQL upload their schema and table properties to the configured metastore. If you are using an external metastore, you will be able to see Delta Lake information in the metastore. Delta Lake tries to keep this information as up-to-date as possible on a best-effort basis. You can also use the DESCRIBE <table> command to ensure that the information is updated in your metastore.
• Databricks SQL does not support zone offsets like 'GMT+8' as session time zones. The workaround is to use a region based time zone like 'Etc/GMT+8' instead. See SET TIME ZONE for more information about setting time zones.

Frequently asked questions (FAQ)

• How are Databricks SQL workloads charged?
• Where do SQL endpoints run?
• Can I use SQL endpoints from Data Science & Engineering workspace SQL notebooks?
• I have been granted access to data using a cloud provider credential. Why can't I access this data in Databricks SQL?

How are Databricks SQL workloads charged?

Databricks SQL workloads are charged according to the Standard Jobs Compute SKU.

Where do SQL endpoints run?

Like Azure Databricks clusters, SQL endpoints are created and managed in your Azure account. SQL endpoints manage SQL-optimized clusters automatically in your account and scale to match end-user demand.

Can I use SQL endpoints from Data Science & Engineering workspace SQL notebooks?

No. You can use SQL endpoints from Databricks SQL queries, BI tools, and other JDBC and ODBC clients.

I have been granted access to data using a cloud provider credential. Why can't I access this data in Databricks SQL?

In Databricks SQL, all access to data is subject to data access control, and an administrator or data owner must first grant you the appropriate privileges.
