Simple sample of a long mysql query I did for a module.
<?php
$sql = db_query(
" SELECT * FROM
((SELECT field_pack_upc_value AS upc , nid FROM content_type_bar_code )
UNION
(SELECT field_box_upc_value AS upc , nid FROM content_type_bar_code )
UNION
(SELECT field_case_upc_value AS upc , nid FROM content_type_bar_code )
ORDER BY upc, nid ) AS b WHERE SUBSTRING(upc,-6) LIKE '%s'
AND nid != %d "
, $pack, $node->nid );
?>
