Question

我想离开加入两个表access_event_logs和hrm_personal_information它的工作完美。

 Query is:
        select concat(first_name," ",middle_name," ",last_name) as Name, 
        h.TIMESTAMPS, 
        a.PBI_ID 
        from 
        access_event_logs h LEFT JOIN hrm_personal_information a on h.USERID=a.PBI_ID 
        WHERE 1 group by DATE(h.TIMESTAMPS);

但是我使用运算符左连接之间的条件无法工作。

   Query is:
    select concat(first_name," ",middle_name," ",last_name) as Name, 
    h.TIMESTAMPS, 
    a.PBI_ID 
    from 
    access_event_logs h LEFT JOIN hrm_personal_information a on h.USERID=a.PBI_ID 
    WHERE h.USERID=100032 and
    h.TIMESTAMPS between '2015-11-02' and '2016-11-20'
     group by DATE(h.TIMESTAMPS);

我该如何解决？请帮帮我。

Answer 1

作为时间戳，您需要将时间戳字段转换为日期或在比较中添加时间

喜欢

date(h.TIMESTAMPS) between '2015-11-02' and '2016-11-20'

或

h.TIMESTAMPS between '2015-11-02 00:00:01' and '2016-11-20 23:59:59'

左边连接条件和使用操作符两个日期列
