Actually it's not a total and can't be calculated. The idea is that as users (with individual id_client keys) add rows the id of the row is auto incremented for their key only. Example:
If user A adds 3 rows: id id_client --------------- 1 A 2 A 3 A and then user B adds 2 rows id id_client --------------- 1 A 2 A 3 A 1 B 2 B I am not looking for a sum of each client's records... that's an easy query... I need the auto incremental id's for each client.
