I finally got around to testing the SQL statement that Steve suggested
The subselect
SELECT RRN(F) from FILEA F where FIELDA='X'
Fetch first 1500 rows only
worked fine on its own
but when I attempted to run the whole thing, like Robert, I received
Keyword FETCH not expected. Valid tokens: ) UNION EXCEPT.

I'll probably have to write a quick RPG program instead.
Thanks to everyone who replied to my request

I had the same solution but FETCH was not allowed in the subselect.

This should work:

UPDATE FILEA F
SET FIELDA = 'N' where RRN(F) in

(
SELECT RRN(F) from FILEA F where FIELDA='X'
Fetch first 1500 rows only
)

Hi everyone
(Hopefully) A quick sql question.
I have a simple SQL update
UPDATE FILEA SET FIELDA = 'N' WHERE FIELDA = 'X'

However there are thousands of records that will be updated. I only need

to

update the first 1500 of these records (no other selection criteria, just
the first 1500)

Is this possible?
If so, how?

Thanks in advance
