Question

I want to calculate how much space my databases are using in a server. I could use sp_spacefiles or query sys.databases table but that would give me separate results for each database and I would have to copy that into an excel sheet and calculate the sum from there.

Is there a direct way of doing it in T-SQL?

Thanks.

You can query master.sys.master_files:

SELECT CONVERT(DECIMAL(10,2),(SUM(size * 8.00) / 1024.00 / 1024.00)) As UsedSpace
FROM master.sys.master_files

This will give you a total in GB.

Sys.Master_files is a server-wide view that lists every file in every DB. It’s available from SQL Server 2005 onward.
