And that's true...but that one quick statement in Interactive SQL
seems so inviting. :)

I don't think this plays to SQL's strengths.  You'd be able to do this fairly 
easily with the RPG cycle, using primary/secondary files by matching keys.  RPG 
lets you compare the record format data, so only one test is needed to 
determine whether the primary and secondary records are alike.

The cycle is not really necessary, but it plays nicely with your 
requirements....

Subject: Using SQL for File Record Comparison


Does this make sense? Is there a better way? I'm trying to find out if
two files are the same. Here's my SQL statement:

SELECT count(*) FROM firstlib/mhrdclp a, secondlib/mhrdclp b where
a.mdvnda = b.mdvnda and a.mdmdl = b.mdmdl and (a.mddual <> b.mddual
or a.MDCMFRT <> b.MDCMFRT or a.MDLP <> b.MDLP or a.MDSF <> b.MDSF)

File MHRDCLP has the following fields:
mdvnda
mdmdl
mddual
mdcmfrt
mdlp
mdsf

I want to see if I have any records that match mdvnda and mdmdl have
any of the other four fields different.

Thanks!
