The Ultimate Guide to High Availability with MariaDB

Getting Result for Counted and Not Counted Record.

I have 3 tables.

tags, posts and poststags

The poststags table hold tags.id and posts.id so I can assign multiple tags to a post.

I wanted to count the total number of tags used including zero (0) count.

Sample result:
tag A - count = 5
tag B - count = 10
tag C - count = 0
tag D - count = 25

etc...

All I can think of is create two statements:

SELECT * FROM tags;

Then while traversing each record:

SELECT COUNT(pt.tagid) FROM poststags pt
LEFT JOIN posts p ON p.id = pt.postid
WHERE p.published = 'yes' AND pt.tagid = /* current tag id from first statement */

Is it possible to create 1 single SQL statement instead of 2 and get the same result?

Answer Answered by Daniel Black in this comment.

SELECT t.name, COUNT(*)
FROM tags t
LEFT JOIN poststags pt ON pt.tag_id = t.id
GROUP BY t.id

LEFT JOIN is so 0 count tags can be achieved.
