MySQL: Selecting a row where a column equals the ID

Question

This is my query:

SELECT ID FROM wp_posts 
WHERE post_type = 'vreb_property'
AND post_status = 'publish' 
ORDER BY post_modified DESC

In this scenario, I need to modify my query to include WHERE post_parent = ID ... so the ID that is being selected, I need to use.

SELECT ID FROM wp_posts WHERE post_type = 'vreb_property' ... and also select records where 'post_parent' = ID

Because there are records that are of post_type "attachment" that I need to grab.

Could I get a few eyes just to clarify the validity of this request? Thanks.

Answer 1

Are you looking for OR ?

SELECT ID FROM wp_posts 
WHERE (post_type = 'vreb_property'
       AND post_status = 'publish')
   OR (post_type = 'attachment'
       AND post_parent = ID)
ORDER BY post_modified DESC

Using the brackets you can adapt it to your specific needs as that is not completely clear.
