About
- Purpose: specifications for all SMW Objects where the value is a possible wiki page title (existing or not)
- Refers to: smw_object_ids
SQL
CREATE TABLE `smw_di_wikipage` (
`s_id` int(8) unsigned NOT NULL,
`p_id` int(8) unsigned NOT NULL,
`o_id` int(8) unsigned DEFAULT NULL,
KEY `s_id` (`s_id`,`p_id`),
KEY `p_id` (`p_id`,`o_id`),
KEY `o_id` (`o_id`)
) ENGINE=InnoDB DEFAULT CHARSET=binary
Example
SELECT s_id,p_id,o_id
, s.smw_namespace AS s_namespace
, CAST(s.smw_title AS char) AS s_title
, p.smw_namespace AS p_namespace
, CAST(p.smw_title AS char) AS p_title
, o.smw_namespace AS o_namespace
, CAST(o.smw_title AS char) AS o_title
FROM
((smw_di_wikipage AS r
LEFT JOIN smw_object_ids AS s ON r.s_id=s.smw_id)
LEFT JOIN smw_object_ids AS p ON r.p_id=p.smw_id)
LEFT JOIN smw_object_ids AS o ON r.o_id=o.smw_id
ORDER BY s_id, p_title, o_title
- p_namespace will probably always be the "property:" namespace, which defaults to 102 (unless there's some way to use a page outside that namespace as a property)
