@@Version - Transact SQL Configuration Functions
Returns system and build information for the current installation of SQL Server.
The @@VERSION results are presented as one nvarchar string. You can use the SERVERPROPERTY (Transact-SQL) function to retrieve the individual property values.
For SQL Server, the following information is returned.
SQL Server version
SQL Server build date
SQL Server edition
Operating system version
For Azure SQL Database, the following information is returned.
Edition- "Microsoft SQL Azure"
Product level- "(RTM)"
We are aware of an issue where the product version reported by @@VERSION is incorrect for Azure SQL Database. The version of the SQL Server database engine run by Azure SQL Database is always ahead of the on-premises version of SQL Server, and includes the latest security fixes. This means that the patch level is always on par with or ahead of the on-premises version of SQL Server, and that the latest features available in SQL Server are available in Azure SQL Database.
To programmatically determine the engine edition, use SELECT SERVERPROPERTY('EngineEdition'). This query will return '5' for standalone databases and '8' for managed instances in Azure SQL Database.
We will update the documentation once this issue is resolved.
A: Return the current version of SQL Server
The following example shows returning the version information for the current installation.
SELECT @@VERSION AS 'SQL Server Version';
Examples: Azure SQL Data Warehouse and Parallel Data Warehouse
B. Return the current version of SQL Data Warehouse
SELECT @@VERSION AS 'SQL Server PDW Version';
