sp_spaceused
-
Is it possible to modify system store proc sp_spaceused. how?
Usually when you execute sp_spaceused 'emp' the result set has name,rows,reserved,date,index_size,unused for table emp
But I need another column to be added where it displays the data
-
sp_spaceused is stored in MASTER database.
Make a copy and edit as you wish.

yeah I cehcked my master db and read that but
I wud like to know how i can change tht for
getting data for the table where datepart(yyyy,convert(char(10),cast(date - 36161 as datetime),101))=1995

I don't think you want to change this proc. Maybe add your own to master as sp_spaceused_2 or something.
Be sure you keep a copy elsewhere. If you rebuilt the master db or moved to a new server, etc., the proc won't exist.

Peter, any way you guys can suppress the double spacing? And, which editor are you using (I like the colors)

Don't change anything that's owned by the system... period.
Make a copy of sp_SpaceUsed under a different name and then make all the changes you want.

I'm not Peter, but that looks a lot like QA to me, based on the colors.
-
I've noticed if you cut and paste directly from QA or SSMS (where everthing is single spaced) ends up double spaced here. I usualyy use UltraEdit as an intermediare so that things don't double space, but then I lose the colors.
-
I use SSMS2008.
The fun thing is that if I copy and paste the code to MS Word first, copy the code from MS Word and paste here, I get single line spaces.
