sql server BETWEEN and

1、用between and 查询时间

SELECT * FROM dbo.CHECKINOUT where USERID='17953' AND CHECKTIME BETWEEN'2013-03-16' AND '2013-03-21'

数据库中明明有3月21的数据记录，但用BETWEEN and 这种写法就是没查出来 sql server BETWEEN and

改成这种写法就可以查询出来

SELECT * FROM dbo.CHECKINOUT where USERID='17953' AND CHECKTIME BETWEEN'2013-03-16' AND DATEADD(day,1,'2013-03-22')

2、两个sql语句结果不一样，第一条没有查询到结果，第二条才可以查询到结果，应该把小数字放在前面

SELECT *from t_PortGrant where StageID=73 AND PortPrice BETWEEN 270 AND 100
SELECT *from t_PortGrant where StageID=73 AND PortPrice BETWEEN 100 AND 270
