Answer 1

Check Database Size in SQL Server for both Azure and On-Premises-

Method 1 – Using ‘sys.database_files’ System View

SELECT
    DB_NAME() AS [database_name],
    CONCAT(CAST(SUM(
        CAST( (size * 8.0/1024) AS DECIMAL(15,2) )
    ) AS VARCHAR(20)),' MB') AS [database_size]
FROM sys.database_files;

Method 2 – Using ‘sp_spaceused’ System Stored Procedure

EXEC sp_spaceused ;
