Optimize SQL for term exclusions
|Reported by:||scribu||Owned by:||scribu|
When calling WP_Query with an argument like 'cat=-1', the WP_Tax_Query::get_sql() method uses a dependant subquery to retrieve posts that don't belong to that category.
This can be achieved in a more efficient way by using a LEFT JOIN.
