FETCH FIRST N ROWS is only supported in the outer level of a query and in a
derived table, not in a subquery (which is where you are trying to use it).
What you can do is push the clause one level deeper into a derived table.
UPDATE FILEA F
SET FIELDA = 'N' where RRN(F) in
( SELECT R FROM
(
SELECT RRN(F) R from FILEA F where FIELDA='X'
Fetch first 1500 rows only
) X
)
This has been supported since V5R2.

Subject: RE: Update the first 1500 records that need updating
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
