Query Question

Here is the last part of my MySql query $sql being the inserted stuff. How would I incorporate something like

$lastid = mysql_insert_id() into the query to I can give a value to the last inserted to use it later in the document

you do not need to use it in an actual query, just execute it immediatly following the insert and the $lastid variable will hold the value of the id that was assigned to the data you inserted into the table.
