Preview
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? |
| Convert to Hyperscale with geo-replicas (preview) | The ability to convert a geo-replicated database non-Hyperscale database to Hyperscale using T-SQL, REST API, PowerShell, or Azure CLI is currently a preview feature. For more information, see Blog: Hyperscale conversion support for geo-replicas. |
| DATEADD number allows bigint | For DATEADD (datepart , number , date ), number can be expressed as a bigint. For more information, see DATEADD (Transact-SQL). |
| Data Virtualization for Azure SQL Database | Data virtualization, now in preview in Azure SQL Database, enables you to leverage all the power of Transact-SQL (T-SQL) and seamlessly query external data from Azure Data Lake Storage Gen2 or Azure Blob Storage. For more information, see Data virtualization with Azure SQL Database (Preview). |
| 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. |
| Microsoft Entra server principals | The ability to create server principals (logins) for Microsoft Entra identities in Azure SQL Database is in preview. |
| 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. |
