Hey, that's a nice idea :-)


  2 - The session could call other SPs. That would mess up the results. You may want to execute a controlled run of the "master" SP on a dev/test system and pull the results from there.  


This will be no problem, when a SP is CALLed the "RequestNum" will not change for all statements submitted within this CALL, only the InternalRequestNumber increases, so this works event if multiple SPs are called:

     SELECT
         querytext,
         MIN(starttime)
     FROM dbc.qrylog
     WHERE (sessionid, RequestNum)
     IN (SEL sessionid, RequestNum
           FROM dbc.qrylog
           WHERE querytext LIKE '%CALL nestedproc%'
           AND statementtype = 'CALL')
     AND statementtype = 'CALL'
     AND RequestNum <> InternalRequestNum -- to exclude the callin SP GROUP BY 1 ORDER BY 2 DESC
