I am trying to get some rows from the same table. It's a user table: user has user_id
and user_parent_id
.
I need to get the user_id
row and user_parent_id
row. I have coded something like this:
SELECT user.user_fname, user.user_lname
FROM users as user
INNER JOIN users AS parent
ON parent.user_parent_id = user.user_id
WHERE user.user_id = $_GET[id]
But it doesn't show the results. I want to display user record and its parent record.
I think the problem is in your JOIN
condition.
SELECT user.user_fname,
user.user_lname,
parent.user_fname,
parent.user_lname
FROM users AS user
JOIN users AS parent
ON parent.user_id = user.user_parent_id
WHERE user.user_id = $_GET[id]
Edit:
You should probably use LEFT JOIN
if there are users with no parents.
