Re: need SQL logic to find out way's to Implement check sum to validate table data is migrated correctly

Hi

Why do you need checksums? Can you not employ a full outer join? My though behind this is that checksumming is quite costly cpuwise and you have to fiddle with each and every relevent column, be it as part of the checksum string be it as part of the joiner. The joiner would have the advantage that you could, if you wanted, also implement logic to tell you precisely in which columns the difference is encountered.

Kind regards
