You might be onto something, couldn't get your suggestion to work out the
box but after looking at the docs
http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html#function_group-concat
Came the following
SELECT GROUP_CONCAT(tags.name SEPARATOR ' ') as tags, `taggings`.* FROM
`tags
LEFT JOIN `taggings` ON (tags.id = taggings.tag_id) WHERE (tags.name IN
('vegetarian', 'soup')) GROUP BY taggings.taggable_id ORDER BY tags
Gives me two records but only one of them has both tags in the concat
column. I can then pretty much do a length check on the tags column and see
when its less than the original input
Wasn't aware of the DROUP_CONCAT function. Cheers for pointing it out.
