Question

Why does this return 23 rows (the right amount):

select users.user_id, users.fname, users.lname, 
       stars.stars, comments.comment from users 
       LEFT JOIN stars on users.user_id = stars.userid 
       JOIN comments on users.user_id = comments.sender 
       where users.user_id = ? order by comments.time desc;

and this return 1 row?:

select users.user_id, users.fname, users.lname,
       stars.stars, count(distinct comments.id) as amount,
       comments.comment from users 
       LEFT JOIN stars on users.user_id = stars.userid 
       JOIN comments on users.user_id = comments.sender 
       where users.user_id = ? order by comments.time desc;

Cheers.

Answer 1

you need to group the main data or do a sub-query for the field.
