Re: SQL Troubles

John, why couldn't you use a join logical over the two, ordered by check number 
and invoice?  I realize it would be a little more overhead, but it seems that 
it would process like lightning.  If this is something you do regularly, it 
might be worth it.

>Yes that works - but when I add in the sort criteria the performance
just isn't there.  Split up into separate statements the record
selection is pretty fast.  With a combined statement it takes about 20
seconds to return the result.  So what I need to do is have it select
the records from APDIST, Find the matching records from APINVOICV and
then perform the ORDER BY Clause.  The last two steps should take
minimal processing time since there are usually less then 10 invoices
and the file is keyed on VOUCHER.
