complex sched task, need vb to execute 4 sql queries in one connection

[bulbasnore]

This works great in phpmyadmin, but if I enclose all statements together or individually in

PHP Code:

$vbulletin->db->query_write("
<statements>
"); 


noting happens (no errors, task mgr reports running just no results).

Any clues? Does vB not support creating temp tables in this way?

create temporary table infraction6mo 
  (iID Integer Primary Key, 
  iName varchar(255), 
  iTot integer);

Insert into infraction6mo 
  SELECT infraction.userid as iID, user.username as iName,SUM( infraction.points ) AS iTot 
  FROM `user`,`infraction` 
  WHERE infraction.dateline > (unix_timestamp()-15724800) and user.userid = infraction.userid and infraction.action = 1 
  GROUP BY infraction.userid 
  ORDER BY itot DESC;
update user set adminoptions = 1 where usergroupid = 2;
update infraction6mo,user set user.adminoptions = 0 
  WHERE infraction6mo.iID = user.userid and infraction6mo.iTot >= 30;
