基于日期从三个表中查询MySQL

Question

I'm trying to get user information based on their subscription startdate in MYSQL.

This is what i've come up with this far..

    SELECT a.id, a.user_login, a.user_email, c.cardtype, c.accountnumber, a.user_pass, a.user_registered
    FROM users a
    INNER JOIN memberships_users b
    ON b.user_id = a.id
    INNER JOIN memberships_order c
    ON c.user_id = a.id
    WHERE b.status = 'active' AND 
          (c.cyckle_period = 6 AND 
          ('2016-06-01 00:00:00' < (SELECT c.startdate ORDER BY c.startdate DESC LIMIT 1)) 
          OR 
          (c.cyckle_period = 1 AND 
          ('2015-12-01 00:00:00' < (SELECT c.startdate ORDER BY c.startdate DESC LIMIT 1));

This query gives me error message "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LIMIT 0, 30' at line 8".

Answer 1

I don't see any LIMIT 0, 30 in your posted code. did you post the right code? BTW, your this below part is totally wrong

'2015-12-01 00:00:00' < (SELECT c.startdate ORDER BY c.startdate DESC LIMIT 1)

It should rather be

'2015-12-01 00:00:00' < SELECT max(startdate) FROM memberships_order

Change your WHERE part like below

WHERE b.status = 'active' AND 
      c.cyckle_period IN (6, 1) AND 
      '2015-12-01 00:00:00' < (SELECT max(startdate) FROM memberships_order);

Answer 2

I think you are just missing right parenthesis. According to me it should be,

SELECT a.id, a.user_login, a.user_email, c.cardtype, c.accountnumber, a.user_pass, a.user_registered FROM users a INNER JOIN memberships_users b ON b.user_id = a.id INNER JOIN memberships_order c ON c.user_id = a.id WHERE b.status = 'active' AND (c.cyckle_period = 6 AND ('2016-06-01 00:00:00' < (SELECT c.startdate ORDER BY c.startdate DESC LIMIT 1))) OR (c.cyckle_period = 1 AND ('2015-12-01 00:00:00' < (SELECT c.startdate ORDER BY c.startdate DESC LIMIT 1)));
