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

Also, you can use MySQL function named

FIELD(HAYSTACK, value[, ...values]).

This function returns index of haystack in values (FROM 1 to n, 0 - if not found).

Example

ORDER BY FIELD(wp_postmeta.meta_key, 'featured', wp_postmeta.meta_key), 
FIELD(wp_postmeta.meta_value, 'yes', wp_postmeta.meta_value), wp_posts.post_date DESC

But, in your case, use the mathematical.coffee example. In my example you need to repeat the field name in the end of list, because if you don't - it will return 0 (zero) and elements than not in list will be first in result statement.
