Database error in vBulletin 4.2.2:

Invalid SQL:

		DELETE package, route, action, contenttype
		FROM package AS package
		LEFT JOIN route AS route
			ON route.packageid = package.packageid
		LEFT JOIN action AS action
			ON action.routeid = route.routeid
		LEFT JOIN contenttype AS contenttype
			ON contenttype.packageid = package.packageid
		WHERE productid = 'dbtech_vbshout';
