Re: Stored Procedure

I wish that would work.... but I really need to loop through a set of 
records and evaluated the results.  I need to look at the doc_no, then 
doc_type, then check to see if the gj_dollar_amt are equal or sum to 
zero.... and a couple more things.  If I really need to use two cursors... 
how do I setup the SP?  I can seem to get the correct sequence for using two 
cursors.  I can get one cursor to work just fine.

Thanks for any help.

Melissa
