Answer 1

INNER JOIN is what you are looking for

 SELECT * FROM checkin_bonus cb INNER JOIN user_pages up ON cb.user_id = u.users_id where cb.user_id > 18 ORDER BY cb.user_id DES 

Answer 2

You should use Join for this

SELECT c.user_id,u.users_id FROM checkin_bonus AS c 
INNER JOIN user_pages AS u ON c.user_id = u.users_id 
where c.user_id > 18 ORDER BY c.user_id DESC

Answer 3

try this just use join

SELECT cb.user_id,up.user_id FROM checkin_bonus as cb
 JOIN user_pages as up ON cb.user_id = up.user_id 
 where cb.user_id > 18 ORDER BY cb.user_id DESC

Answer 4

SELECT u.user_id as id FROM checkin_bonus as c join user_pages as u on c.user_id =u.user_id WHERE c.user_id>18 ORDER BY c.user_id DESC

Answer 5

Actually whats your field name?? Is it user_id or users_id?

if it is user_id, then please replace join on clause with u.user_id and try.

SELECT u.user_id as id FROM checkin_bonus AS c 
JOIN user_pages AS u ON c.user_id = u.user_id 
where c.user_id > 18 ORDER BY c.user_id DESC

Answer 6

You should use below query to get your desired result.

SELECT A.user_id, SUM(B.score) as total
FROM checkin_bonus A 
JOIN user_pages B 
ON A.user_id = B.user_id
GROUP BY A.user_id
