select * tsk_posts      left join tsk_term_relationships on         (tsk_posts.id = tsk_term_relationships.object_id)      left join tsk_term_taxonomy on          (tsk_term_relationships.term_taxonomy_id = tsk_term_taxonomy.term_taxonomy_id)               tsk_posts.post_status = 'publish'      ,          tsk_posts.post_type = 'post'      ,          tsk_term_taxonomy.taxonomy = 'category'      ,          ( tsk_term_taxonomy.term_id = 4 or tsk_term_taxonomy.term_id = 103 or           tsk_term_taxonomy.term_id = 19 or tsk_term_taxonomy.term_id = 20 or            tsk_term_taxonomy.term_id = 5 or tsk_term_taxonomy.term_id = 2 or            tsk_term_taxonomy.term_id = 14 )     order rand()     limit 1

thank much.

"order rand" can quite expensive query. random number must generated , used access result set.

how many rows in each of tables? there indexes? run explain plan better idea cost is.
