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

It is straightforward like this:

...
ORDER BY featured = 'yes'

featured = 'yes' is evaluates as boolean true or false, for items that featured = "yes" is true will come first then items that has featured = "yes" is false i.e featured = "no" come later.

Update:

You can use CASE statement in the order by clause to sort your data on a sepecific field, something like:

ORDER BY 
        CASE WHEN postmeta.meta_key = 'featured' 
             THEN meta_value = 'yes' DESC  
        END

OR:

ORDER BY ( postmeta.meta_key = 'featured' AND meta_value = 'yes') DESC

You might need to add another order by criteria in the ELSE part of the CASE statement to order the items that have meta_key = 'featured is false to order them by.

If the field metadata_key is always = "featured" then you can get rid of the case statement and use just ORDER BY meta_value = 'yes' DESC
