RE: Remove duplicate records

I can identify the records I posted since the poster id field is a constant, and not available to anybody else.

Can you be sure that all of the duplicates that exist on the file have been
caused by you re-running the program. Does the file have audit date stamps
on it? That way you could use some of the approaches already mentioned but
all check that the duplicate was created after the second time you re-ran
it. This way you might hang on to some genuine duplicates. Apologies if the
nature of the data means that duplicates are always wrong whether created
manually or automatically.

My one piece of advice would be to either save the file off before you fix
it, or if you are using sql turn on journaling.

Regards

Neill

Not to make too simple but a very basic RPG program with a L1
on the fields that make it a duplicate would solve the duplicates in
a hurry.

Maybe 5 lines of code ?

Low risk ...high speed
