[development] db_last_insert_id

[Jeff Greenberg]

I'm confused with the db_last_insert_id function in 
database.mysql-common.inc.


The function is:


function db_last_insert_id($table, $field) {
  return db_result(db_query('SELECT LAST_INSERT_ID()'));
}


and I see no reason whatsoever for there to be any parameters, let alone 
required ones.
