[wp-hackers] MySQL queries to add to wp_postmeta

[Mike Schinkel]

Sorry, that was my code with a test table. Should have been:

==========
INSERT INTO wp_postmeta (post_id,meta_key,meta_value)
SELECT ID,'my_custom_key','false' 
FROM wp_posts 
WHERE ID NOT IN (SELECT post_id FROM wp_postmeta WHERE meta_key = 'my_custom_key')
==========
