Modified SP_who

,

Here is a modified SP_WHO procedure
which returns more information about the current session.
I forgot all the thing that i have added to the sproc, but the last addition shows the last executed TSQL statement.
There might be a better solution to get the values from DBCC rowset, thou I did not have time to think everything through.
If you think you have a better solution, let me know.
Thanks

Good Luck
Dan
