This is probably a silly question to most of you, but I'm in the process
of splitting off years from a large DB to several smaller ones. Some of
the existing smaller DBs already have most of the data for their
respective years. But some of the same data is also on the source DB.
If I simply do an insert keying on the year column, and a row being
inserted from the source DB already exists in the target DB, will a
duplicate row be created?
And if so, how can I avoid that?
Thanks,
John Steen
