The following table lists the features of Azure SQL Database that are currently in preview.
| Feature | Details |
|---|---|
| ABORT_QUERY_EXECUTION | The new ABORT_QUERY_EXECUTION query hint, currently in preview, can block future execution of known problematic queries, for example nonessential queries causing high resource consumption and impacting critical application workloads. For more information, see Query Store hints: Block future execution of problematic queries. |
| Approximate or fuzzy string matching | Check if two strings are similar, and calculate the difference between two strings. Use this capability to identify strings that might be different because of character corruption. What is fuzzy string matching? |
| DATEADD number allows bigint | For DATEADD (datepart , number , date ), number can be expressed as a bigint. For more information, see DATEADD (Transact-SQL). |
| Elastic queries | The elastic queries feature allows for cross-database queries in Azure SQL Database. |
| Elastic transactions | Elastic transactions allow you to execute transactions distributed among cloud databases in Azure SQL Database. |
| Fixed server roles | To simplify permission management, Azure SQL Database provides a set of fixed server-level roles to help you manage the permissions on a logical server. |
| Import and export using Private Link | You can import or export an Azure SQL Database using private link. Leave Allow Access to Azure Services off when you import or export a database using a service-managed endpoint. |
| JSON native data type | The new json data type and JSON aggregate functions provide new capabilities for handling semistructured data in Azure SQL Database. For more information, see JSON Type and aggregates preview. |
| JSON aggregate functions | Two new json aggregate functions JSON_OBJECTAGG and JSON_ARRAYAGG enable construction of JSON objects or arrays based on an aggregate from SQL data. For more information, see JSON Type and aggregates preview. |
| Microsoft Entra server principals | The ability to create server principals (logins) for Microsoft Entra identities in Azure SQL Database is in preview. |
| Regular expression functions | Regular expression (REGEX) functions return text based on values in a search pattern. Regular expressions. |
| Query editor in the Azure portal | The query editor in the Azure portal allows you to run queries against your Azure SQL Database directly from a web browser. |
| Regular expression functions | Regular expression (REGEX) functions return text based on values in a search pattern. Regular expressions. |
| UNISTR (Transact-SQL) | Azure SQL Database now supports the UNISTR T-SQL syntax for Unicode string literals. For more information, see UNISTR (Transact-SQL). |
| || (String concatenation) and ||= (Compound assignment) syntax support | Azure SQL Database now supports || (String concatenation) and ||= (Compound assignment) Transact-SQL syntax. |
