And that's true...but that one quick statement in Interactive SQL seems so inviting. :) On 3/7/07, DeLong, Eric <EDeLong@xxxxxxxxxxxxxxx> wrote:
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....

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.
