两个日期之间的Sql Server where子句不给出预期的输出

Question

这是我使用'between'运算符获取日期的简单查询.

create table dummy (mydate datetime);
 insert into dummy values('2013-03-20 10:30:00.000');
 insert into dummy values('2013-03-21 10:30:00.000');
 insert into dummy values('2013-03-22 10:30:00.000');
 insert into dummy values('2013-03-23 10:30:00.000');
 insert into dummy values('2013-03-24 10:30:00.000');
 insert into dummy values('2013-03-25 10:30:00.000');
 insert into dummy values('2013-03-26 10:30:00.000');
 insert into dummy values('2013-03-27 10:30:00.000');
 insert into dummy values('2013-03-28 10:30:00.000');
 insert into dummy values('2013-03-29 10:30:00.000');
 insert into dummy values('2013-03-30 10:30:00.000');

我使用的qiuery是: select * from dummy where mydate between ('3/01/2013 12:00:00 AM') and ('3/30/2013 12:00:00 AM')

在这里 2013-03-30 10:30:00.000,也应该退货.

更改日期时间格式的where子句中,检查值与>=和<代替.

select * 
from dummy 
where mydate >= '20130301' and
      mydate < '20130401'
