Is there a way to get a list of all current temporary tables in SQL Server?

Question

I realize that temporary tables are session/connection bound and not visible or accessible out of the session/connection.

I have a long running stored procedure that

Answer 1

SELECT left(NAME, charindex('_', NAME) - 1)
FROM tempdb..sysobjects
WHERE NAME LIKE '#%'
    AND NAME NOT LIKE '##%'
    AND upper(xtype) = 'U'
    AND NOT object_id('tempdb..' + NAME) IS NULL

you can remove the ## line if you want to include global temp tables.
