1. 7.x includes/database/database.inc \db_next_id()

Retrieves a unique id.

Use this function if for some reason you can't use a serial field. Using a serial field is preferred, and InsertQuery::execute() returns the value of the last ID inserted.

Parameters

int $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

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