<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>
Examples
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 FROM (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;
</mysql>
