Gord,

That solution doesn't display the RRN's of the duplicates.

Enforcing RI programmatically is a joke.  When you have to merge 
divisions, etc, you're going to have file maintenance outside of the one 
5250 file maintenance program.

RE: Using SQL to check for duplicate records






Hi Rob

I've done this before (on BPCS).

Select iprod, count(iprod) from lib.iim
group by iprod
having count(iprod) > 1

Yhis is fast !!!

But - I'm curious. I know BPCS inforces RI programatically - so - how can
you have duplicates in IIM? Don't tell me - Someone went in outside of 
BPCS
control <BG>.

I don't know if it's more efficient, but try:
SELECT IPROD FROM IIM group by IPROD 
    Having count(*) > 1

That will give you the IPROD values that are duplicated.  If you want the
specific record numbers, you'll have to use the result set to join back to
IIM. 

Hope that helps.

Is there a more efficient way, using SQL, to check for duplicate records
than the following?
SELECT A.IPROD, RRN(A) FROM IIM A
WHERE A.IPROD IN ( 
  SELECT B.IPROD FROM IIM B 
  GROUP BY B.IPROD 
  HAVING COUNT(*) > 1)
