RE: SQL limit with fetch first together with total amount limit

Loek,

Do you want to update records (Status to 'XX' where Status = 'AA' and Curcode = 'EUR') until you hit 50000 records updated or hit 1000 amount updated?
You imply this by mentioning use of FETCH FIRST.

Or do you want to update records (Status to 'XX' where Status = 'AA' and Curcode = 'EUR') only if the whole update is under 50000 records and under 1000 total amount? You imply this by listing A and B and C and D as selection conditions.

Subject: SQL limit with fetch first together with total amount limit

Hi group,

I have to update the status field of a group of records where:
A: The status is 'AA'
and B: The currency code is 'EUR'
and C: The total amount of the selection is less than 1000,00
and D: The total number of records selected must be less or equal to 50.000.

Record fields: Recid, Status, Curcode, Amount, Description

Total number of records is 1.000.000

I know that I can limit the selection with FETCH FIRST, and specifying the
correct status code and currency code can be embeded within the select
clause, but I fail to see how I can limit the selection with a total amount
as a limit for the selexcted records.

Can anyone show me how to aproach this?

Kind regards,

Loek Maartens.
