I am trying to query multiple WordPress tables and I’ve been learning as I go.
Here’s what I have so far
SELECT
tr.object_id,
tr.term_taxonomy_id,
p.ID,
p.post_date,
p.post_title,
p.post_excerpt,
p.guid,
t.term_id,
t.name,
tt.taxonomy
FROM
wp_116_term_relationships AS tr,
wp_116_posts AS p,
wp_116_terms AS t LEFT JOIN
wp_116_term_taxonomy as tt ON tt.term_id = t.term_id
WHERE
p.post_type = 'post'
AND p.ID = tr.object_ID
AND tr.term_taxonomy_id = tt.term_taxonomy_id
AND p.post_date > '2013-06-01'
Here’s what I get (sorry I couldn’t figure out how to post this cleaner – hope it makes sense)
object_id term_taxonomy_id ID post_date post_title post_excerpt guid term_id name taxonomy
2356 33 2356 2013-06-07 15:56:54 Test Post for Reports http://domain.com/?p=2356 7496 Marketing Updates category
2356 32 2356 2013-06-07 15:56:54 Test Post for Reports http://domain.com/?p=2356 470 News Updates category
2356 70 2356 2013-06-07 15:56:54 Test Post for Reports http://domain.com/?p=2356 46408 Tag Test 1 post_tag
2356 72 2356 2013-06-07 15:56:54 Test Post for Reports http://domain.com/?p=2356 46410 Tag Test 2 post_tag
2356 74 2356 2013-06-07 15:56:54 Test Post for Reports http://domain.com/?p=2356 46412 Tag Test 3 post_t
How do I separate the data from the name field so that if it’s a post_tag it’s in one column (post_tag) and if it’s a category it’s in another (category)? For example:
object_id term_taxonomy_id ID post_date post_title post_excerpt guid term_id post_tag category
2356 33 2356 2013-06-07 15:56:54 Test Post for Reports http://domain.com/?p=2356 7496 Marketing Updates Tag Test 1
Should be fairly straight forward with a CASE statement
