ORDER BY an equal value in MySQL

Question

All, I\'ve got the following SQL query as of now:

SELECT * FROM $wpdb->posts
JOIN $wpdb->term_relationships ON $wpdb->term_relationships.object_id=$         


        

Answer 1

SELECT ...
FROM   ...
ORDER BY (meta_key='featured' AND meta_value='yes') DESC, postid ASC;

If (meta_key='featured' AND meta_value='yes') for a row, that row will have a 1/TRUE. Otherwise, it will have a 0/FALSE. Hence, sorting descending puts the rows that have TRUE first.
