Is there a stored procedure anyone has that will list all the active temp tables being used by all the databases in SQL Server?

This will get it for you. I don't know if there's a way to tie the name back to the creating SPID though. don't think so.

SELECT * FROM tempdb..sysobjects WHERE NAME LIKE '#%' AND xtype = 'U'

One doubt... This query returned tables with names like '#042A2C58' , '#0626B80C' etc. Iam sure these temp tables have not been created by the developers or any other users. Nor are they created inside any procs.

Those are table variables. Unlike temp tables, the name that they are given in code has no relation to the name assigned in TempDB.

It's also possible that temp tables created by various system processes appears in the list. I'm not sure if there's any way to find the process that created a temp object, and thereby filter out ones created by the system.

just for fun:

select name

from tempdb..sysobjects

where name like '#%'--> table variables

and name not like '#[A-Z,a-z]%' --> temp tables

select name

from tempdb..sysobjects

where name like '#[A-Z,a-z]%'--> temp tables

select name

from tempdb..sysobjects

where name like '#%'--> temp tables and table variables

I just ran into an old article - it seems to be the 'holy grail' (or at least a piece of it) regarding tebp table creation ...
