我的表结构是:

SELECT * FROM `MYTABLE` WHERE `USERID` = 148 ORDER BY `TABLEDATE` DESC;

ID  USERID STATE_ID   TABLEDATE              
96  148    13         2013-01-08 06:11:34   
554 148     3         2013-01-03 04:46:08   
25  148     2         2013-01-02 04:46:07   

我希望在表“MYTABLE”(=> order by STATE_ID DESC limit 1,1)中的用户的第二个最高条目,其日期最后一个条目是日期“2013-01-08”。

我尝试形成查询但失败了。请帮忙?

SELECT F1.USERID,
  MAX(F2.TABLEDATE),
  F2.STATE_ID
FROM MYTABLE F1 
 JOIN MYTABLE F2 ON F1.USERID = F2.USERID WHERE
   F1.STATE_ID = 13 AND
   F2.TABLEDATE < F1.TABLEDATE AND
   F1.TABLEDATE <= '2013-01-08 23:59:59' AND
   F1.TABLEDATE >=  '2013-01-08 00:00:00' 
 GROUP BY F1.USERID 

输出

148 2013-01-03 04:46:08 2

预期产出

148 2013-01-03 04:46:08 3

如果您想要具有第二高值的行,State_ID您可以简单地执行以下操作:

SELECT *
FROM 
(
   SELECT *
   FROM yourTable
   LIMIT 2
) AS sub
ORDER BY State_ID 
LIMIT 1;
