Question

I’m running this SQL query

$sql = "select images.image, images.comment as feedDescription, 
        customers.fullName, CONCAT('[', GROUP_CONCAT(DISTINCT likes.uid),']') as likes, 
        CONCAT('[', GROUP_CONCAT(DISTINCT CONCAT('{\"userid\":\"', comments.fid, '\", \"comment\":\"', comments.comment, '\"}') separator ','),']') as comments 
        FROM images 
        LEFT JOIN customers on images.client_id = customers.client_id 
        LEFT JOIN likes on images.image = likes.image 
        LEFT JOIN comments on images.image = comments.image 
        WHERE images.fid=:userID 
        ORDER BY images.image LIMIT $offset,$limit";

the only problem is that I am getting only the first row …

I have images table, customers table (taking the name of the customer by the id i got in the images), likes table (people who did “like” on the image) and comments (people who wrote “comments” on the table)

Answer 1

You are using an aggregation function on a query, so MySQL is automatically returning only one row — the aggregation of all the data.

In other databases, this would produce an error, because you have a mixture of aggregated and non-aggregated columns. This is a (mis)feature of MySQL called “hidden columns”.

Add a group by to your query to fix the problem:

group by images.image, images.comment, customers.fullName

Be sure to add this after the WHERE clause and before the ORDER BY.
