Get Database Size in SQL Server Using T-SQL

Today's quick tip: get the size of your database in SQL Server (including SQL Azure) by using a T-SQL statement.

Connect to your database, and execute this query:

SELECT ( (SUM(Reserved\_Page\_Count) \* 8.0) / 1024 / 1024 ) AS DatabaseSizeInGigabytes FROM sys.dm\_db\_partition\_stats

Very useful in Azure where it's not easy or apparent to get the database's total size.
