I have a query that creates a table view and then another that queries the view. The results are extremely slow. Here is the code:

create or replace view $view_table_name as select * from wp_2_postmeta where post_id IN (                           
                        select ID FROM wp_2_posts wposts 
                            LEFT JOIN wp_2_term_relationships ON (wposts.ID = wp_2_term_relationships.object_id) 
                            LEFT JOIN wp_2_term_taxonomy ON (wp_2_term_relationships.term_taxonomy_id = wp_2_term_taxonomy.term_taxonomy_id) 
                        WHERE wp_2_term_taxonomy.taxonomy = 'category'
                            AND wp_2_term_taxonomy.parent = $cat || wp_2_term_taxonomy.term_id = $cat                                                                                                                       
                            AND wposts.post_status = 'publish' 
                            AND wposts.post_type = 'post')

The $values have been put it in for this example that queries the view table for the results.

select distinct(ID) from $view_table_name wposts LEFT JOIN wp_2_postmeta wpostmeta ON wposts.ID = wpostmeta.post_id WHERE post_status = 'publish' AND ID NOT IN (SELECT post_id FROM wp_2_postmeta WHERE meta_key = '$var' && meta_value = '$value1') AND ID NOT IN (SELECT post_id FROM wp_2_postmeta WHERE meta_key = '$var' && meta_value = '$value2') AND ID NOT IN (SELECT post_id FROM wp_2_postmeta WHERE meta_key = '$var' && meta_value = '$value3') AND postmeta.meta_key = 'pd_form' ORDER BY CASE wpostmeta.meta_value WHEN '$value5' THEN 1 WHEN '$value6' THEN 2 WHEN '$value7' THEN 3 WHEN '$value8' THEN 4 WHEN '$value9' THEN 5 THEN '$value10' THEN 6 WHEN '$value11' THEN 7 WHEN '$value11' THEN 8 END
