SELECT page.page_id, page.page_keyword FROM page WHERE page.page_id<>6 AND page.page_id NOT IN ( SELECT page_links.child_id FROM page_links WHERE page_links.page_id=6 )
The table `page_links` contains "parent" (page_links.page_id) and "child" (page_links.child_id) mappings for items in `page`. Given a page.page_id=6, I want all items in `page` that satisfy the following:
page.page_id<>6
and
page.page_id<>page_links.child_id only where page_links.page_id=6
So, for a given page, I want all possible child page candidates (condition is that current child pages and the given page are not possible candidates).
Thanks in advance!
