db_next_id($existing_id = 0)

Retrieves a unique id.

Use this function if for some reason you can't use a serial field, normally a serial field with db_last_insert_id is preferred.

Parameters

$existing_id After a database import, it might be that the sequences table is behind, so by passing in a minimum ID, it can be assured that we never issue the same ID.

Return value

An integer number larger than any number returned before for this sequence.
