<mysql>CREATE TABLE `smw_inst2` (

 `s_id` int(8) unsigned NOT NULL,
 `o_id` int(8) unsigned DEFAULT NULL,
 KEY `s_id` (`s_id`),
 KEY `o_id` (`o_id`)

) ENGINE=InnoDB DEFAULT CHARSET=binary;</mysql>


This is probably correct, based on field names and convention found in other tables, but still not sure what it means: <mysql> SELECT s_id, o_id

 , CAST(s.smw_title AS char) AS s_title
 , CAST(o.smw_title AS char) AS o_title
   (smw_inst2 AS i
   LEFT JOIN smw_ids AS s ON i.s_id=s.smw_id)
   LEFT JOIN smw_ids AS o ON i.o_id=o.smw_id;
