Hy every body,

I'm looking for a database who compare 2 tables:

I wanna made a database who import 2 tables A and B and compare them.

thanks

This is a schronisation issue.

Best to start with the synchronisation rules: decide what to do when the records are compared.

Record A is newer than Record B

Record B is newer than Record A

Record does not exist in A

Record does not exist in B

And so on.

Belive it or no, getting these rules worked out is usually the most difficult part. The synchronisation is technically relatively easy: loop through the records and move data between tables with Set Field calculations. Or perform an import to update the existing records.
