Question

此查询不适用于mysql v 5.7.18。

但是这个查询在过去的mysql版本（5.5.46）

中运行得很好

SELECT car_id FROM (
                    SELECT car_id ,
                      CASE  WHEN ( unix_timestamp(STR_TO_DATE( car_from, '%Y-%m-%d %H:%i:%s' ))  > unix_timestamp(STR_TO_DATE( '2017-03-15 13:00', '%Y-%m-%d %H:%i:%s' ))
                                  || unix_timestamp(STR_TO_DATE( '2017-03-09 17:00', '%Y-%m-%d %H:%i:%s' )) > unix_timestamp(STR_TO_DATE(  car_to , '%Y-%m-%d %H:%i:%s' ))
                                  || unix_timestamp(STR_TO_DATE( '2017-03-15 13:00', '%Y-%m-%d %H:%i:%s' )) < unix_timestamp(STR_TO_DATE( '2017-03-09 17:00', '%Y-%m-%d %H:%i:%s' ))
                                  || unix_timestamp(STR_TO_DATE(  car_to, '%Y-%m-%d %H:%i:%s' )) < unix_timestamp(STR_TO_DATE(  car_from, '%Y-%m-%d %H:%i:%s' ))
                                )  THEN 0
                    ELSE 1 END as intersect_time
                    FROM car_booking_master
                    WHERE state = '1'
                    GROUP BY car_id
                    HAVING intersect_time =  1
                    ) AS virtual

在新的mysql版本上我收到此错误

#1064 - 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 'virtual
LIMIT 0, 25' at line 15

Answer 1

mysql版本的问题是我正在使用的关键字＆＃34;虚拟＆＃34; 。使用＆＃34; v＆＃34;代替＆＃34;虚拟＆＃34;查询工作正常

Answer 2

如果您尝试为子查询添加别名，则应删除最后一行中的IF (@value < 0) BEGIN RAISERROR('Invalid parameter: @value cannot be less than zero', 18, 0) RETURN END。

子查询不适用于mysql（版本5.7.18）
