Try changing this:

exec @proc @objname =

@TABLE_NAME ,@updateusage = 'true'

to this:

exec @proc @objname =

@TABLE_NAME ,@updateusage = 'false'

You won't have updated usage numbers, but the output should be reasonably accurate.

You could execute this command at the database level at some time when the load on the system is not so heavy to update the usage:

dbo.sp_spaceused @updateusage = 'true'

It would probably have been better to post this question on the orginal thread where you got it:

It may not do everything you're trying to do but it will give you a hint on how to lose that awful cursor. 😉 Please see the following post...

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
