table prefix screwing with my mod

[killa seven]

PHP Code:

$vbulletin->db->query_write("CREATE TABLE IF NOT EXISTS ".TABLE_PREFIX."`dbh_champions` (
`title_id` INT( 10 ) NOT NULL AUTO_INCREMENT ,
`title_name` VARCHAR( 50 ) NOT NULL ,
`title_holder`VARCHAR( 50 ) NOT NULL ,
`title_gif` VARCHAR( 150 ) NOT NULL ,
`title_defences` INT( 150 ) NOT NULL ,  
UNIQUE (`title_id`)
) "); 


basically this is the code thats breaking when there is a table prefix

his prefix was vb_
