Question

I have a table of blog posts in one table. In a separate table i have records of images that are stored in a directory that are tied to specific blog posts.

How can i write a query that selects only blog posts that have at least 5 photos?

The BlogPosts table has an ‘ID’ column. The Photos table has a ‘PostID’ column that corresponds to the the BlogPosts’ ‘ID’ column.

$query = "SELECT * FROM BlogPosts WHERE ?"

Answer 1

SELECT * 
FROM BlogPosts 
WHERE ID IN 
    (SELECT PostID FROM photos GROUP BY PostID HAVING count(*) >= 5)
