Using SQLRPGLE to find Dup Records and do Delete?

Hi Jim

When I have exclusive access to a file and can do a CPYF *REPLACE
one method I use to drop duplicate records is create a temporary file
using
CREATE TABLE xxx LIKE yyy
INSERT into xxx (SELECT DISTINCT * from yyy WHERE etc)
DELETE FROM yyy
INSERT into yyy SELECT * from xxx

or replace the DELETE and INSERT with
CPYF xxx yyy MBROPT(*REPLACE)

This assumes you dont care which of the duplicates is removed.
If you need to remove a particular duplicate then this is not the way.
Regards
Frank Kolmann

I have a program that is written in SQLRPGLE to find dup records in a
large file (below is the mainline and select routine). Can I get the
RRN of the record from the fetch of the SQL record? If so I can do a
delete that way.

I'd appreciate any help or suggestions (as I'm not much of an SQL >person
and have not played one on TV).

Thanks,
