Question

所以我想创建一个createview来将时间记录分成4行，但是总是会因为结账而导致错误发生错误（时间在＆＃39; 11：00：00＆＃39;以及＆＃39; 00：00＆＃39;），＃34;所以我的问题是如何根据下面的语法在min（）/ max（）内部使用？

CREATE VIEW absenfinal AS SELECT pin, name, date,
        MIN(time) as login,
        MIN(time BETWEEN '11:00:00' and '12:00:00') as checkout,
        MAX(time BETWEEN '11:00:00' and '12:00:00') as checkin,
        MAX(time) as logout
        FROM tb_tgljam
        GROUP BY date, pin;

工作代码是：

 CREATE VIEW absenfinal AS SELECT pin, name, date,
            MIN(time) as login,
            MAX(time) as logout
            FROM tb_tgljam
            GROUP BY date, pin;

对汇总调用的附加条件使用CASE子句

 MIN(CASE WHEN time BETWEEN '11:00:00' and '12:00:00' THEN time END) as checkout,

如何在createview中的MIN（）/ MAX（）内使用BETWEEN？
