I think SJL's solution is correct - it would select the first 1500 rows
where the value of fielda = 'X', my statement would update the records
in the first 1500 rows where fielda = 'X' thus giving you fewer than
1500 updates.

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
