If you are looking to quickly check your Azure SQL Database’s Tier and Performance Level, the following may assist you:
First connect to the database and then run the following code:
SELECT PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS nvarchar(20)),4) AS Product_Version ,COALESCE(DATABASEPROPERTYEX(DB_NAME(),'Edition'),'NA') AS Tier ,COALESCE(DATABASEPROPERTYEX(DB_NAME(),'ServiceObjective'),'NA') AS Performance_Level
If the Performance Level doesn’t show, you are likely on an older SQL Server 2012 database (Product_Version 11) as these databases do not currently appear to report the value correctly.
