Hi
I have the following tables setup in MYSQL:
Region 1 Region 2
HQ
Tbl1 with autonumbered (PK) Tbl1 with autonumbered (PK)
Tbl1 autonumbered-PK
To explain the above. Basically there are two regions that collect
information and then at the end of each month they have to send the
information to HQ. This is fine, but the problem comes when the
information (the data in the tables) is submitted to HQ. All three
tables have the same names and the same structure. We want to
synchronize the information sent by the regions into one table at HQ.
How can we do this without having the duplicate number problem?
Thanks

The simplest thing would be to have the main table have it's own auto
increment key and use the two sub tables keys as a numerical field,
perhaps as a foreign key.
As a general rule, ai keys should only be used for uniqueness, and not
have any real meaning within the datasets.
