MySQL 联合 2 个表来排序

Question

我的排序不起作用，我想对 table 数据 1

进行排序

SELECT session_id
FROM t_table_1
WHERE dateNew BETWEEN '2015-01-01' AND '2015-01-25'
AND session_id NOT IN ((SELECT distinct session_id FROM t_table_2))
GROUP BY session_id
ORDER BY id DESC LIMIT 0, 20
UNION ((SELECT DISTINCT session_id FROM t_table_2 WHERE status = '0'))

订单无效

Answer 1

这是你想要的吗

SELECT * FROM
(SELECT session_id
 FROM t_table_1
 WHERE dateNew BETWEEN '2015-01-01' AND '2015-01-25'
 AND session_id NOT IN ((SELECT distinct session_id FROM t_table_2))
 GROUP BY session_id
 ORDER BY id DESC LIMIT 0, 20) t
UNION ALL
 ((SELECT DISTINCT session_id FROM t_table_2 WHERE status = '0'))
