mysql - MySQL-在查询中截断日期时间

Question

我有以下查询：

select * from player_source 
where source is not null

这导致

ID      create_dtime
001     2012-10-16 16:13:27
002     2012-12-10 16:13:27

等等...

我想过滤查询，使其仅返回 create_dtime 大于或等于 2012 年 12 月 3 日且小于或等于 2012 年 12 月 9 日的结果。

我尝试使用

select * from player_source 
where source is not null
and Create_Dtime >= To_Date('2012-Dec-03','yyyy-mon-dd')
and Create_Dtime <= To_Date('2012-Dec-09','yyyy-mon-dd')

使用我的 Oracle 根，但它似乎没有用。有什么想法吗？

Answer 1

询问：

select * 
from player_source 
where source is not null
and Create_Dtime >= '2012-10-03'
and Create_Dtime <= '2012-10-09'

Answer 2

尝试这个

 select * 
 from player_source 
 where source is not null
 and Create_Dtime >= '2012-Dec-03'
 and Create_Dtime <= '2012-Dec-09'

Answer 3

语法是：

select * from player_source 
where source is not null
and Create_Dtime > '2012-12-03'
and Create_Dtime <= '2012-12-09'

或者，更简洁地说：

select * from player_source 
where source is not null
and Create_Dtime > '2012-12-03' BETWEEN
and '2012-12-09'
