Re: Duplicate SETGT / READPE combination in SQL?

Perhaps simply using a GROUP BY clause would suffice vs the FETCH FIRST
ROW ONLY

Ugghhh. "fetch first row only" worked, but too well. The problem was
that
I didn't explain that the SETGT / READPE combination query is just a small
part of a larger query, so I need the "fetch first row only" to work for
each account, not for the entire data set.

I'm thinking maybe common table expression (CTE) might be the way to go,
but I may have to essentially duplicate the main query.

Gonna have to think this one through.

I will try this in the morning. How do I restrict the query to return
only
one record?

Perhaps something along this line?

Select * from aaFormsVp Where aaComp = :aaComp and aaState = :aaState

and

aaPLine = :aaPLine
And aaDType = :aaDType And aaRRdate <= :aaRRdate
Order By aaComp, aaState, aaPLine, aaDType, aaRRdate desc
