# Query Changes?

 * Does anyone know if WordPress 2.0 changes the $wpdb class or the way that queries
   are sent? This query works for WP1.5 but returns ‘false’ under WP2:
 * $request = “SELECT post_id FROM $wpdb->postmeta LEFT OUTER JOIN $wpdb->posts 
   ON ID = post_id WHERE post_status = ‘publish’ AND meta_key = ‘featuretitle’ AND
   post_id != ‘$exclude’ ORDER BY rand() LIMIT $display”;
 * $posts = $wpdb->get_results($request);

 * Scratch that, found the problem.
 * The issue stems from the fact that my plugin requires $post_id to be set so it
   can write the correct info to the database. When you’re first creating a post,
   this value hasn’t been set and won’t be set until write_post() has been called.
   I guess my plugin is being called before that happens, so the wrong data is getting
   written (post_id defaulting to zero).
 * Any developers out there know how to approach this issue? Is there a way to get
   $post_id in the Write Post page if the post is brand new?
