SQL has quite a few store procedure one of them is sp_spaceused it’s a useful one to see the space used by the databases however it’s a bit basic.
Now luckily there are some much extended versions that give much more detail and is useful for a number of reasons, one is because it gives the percentages that are used by the data not just the total size.
This is an example of a report that this stored procedure generates. These are the results of running sp_SDS with no input parameters on a testing SQL Server 2005. It generates a database level summary report in megabytes:
To run the stored procedure after it is created use this query:
USE master; EXEC dbo.sp_SDS; |
Run this DDL Query against the Master database to create the stored procedure:
