例子:工作和非工作。

select * from tblUser Where    
convert(varchar(10),CreatedDate,111) between '2015/04/01' and '2016/04/01' //--**Working**

OR

select * from tblUser Where
(CAST(CreatedDate AS DATETIME) between CAST('2015/04/01' AS DATETIME) And CAST('2016/4/30'AS DATETIME)) //--**Working**

OR

select * from tblUser Where
(YEAR(CreatedDate) between YEAR('2015/04/01') And YEAR('2016/4/30')) 
//--**Working**

下面的AND是无效的:

select * from tblUser Where
Convert(Varchar(10),CreatedDate,111) >=  Convert(Varchar(10),'01-01-2015',111) and  Convert(Varchar(10),CreatedDate,111) <= Convert(Varchar(10),'31-12-2015',111) //--**Not Working**


select * from tblUser Where
(Convert(Varchar(10),CreatedDate,111) between Convert(Varchar(10),'01-01-2015',111) And Convert(Varchar(10),'31-12-2015',111)) //--**Not Working**

你应该把这两个日期放在单引号之间，比如..

select Date, TotalAllowance from Calculation where EmployeeId = 1
             and Date between '2011/02/25' and '2011/02/27'

或者可以使用

select Date, TotalAllowance from Calculation where EmployeeId = 1
             and Date >= '2011/02/25' and Date <= '2011/02/27'

请记住，第一次约会包含所有内容，但第二次约会就不包含所有内容，因为它实际上是“2011/02/27 00:00:00”。

select Date,TotalAllowance 
from Calculation 
where EmployeeId=1
  and convert(varchar(10),Date,111) between '2011/02/25' and '2011/02/27'

试试这个:

select Date,TotalAllowance from Calculation where EmployeeId=1
             and [Date] between '2011/02/25' and '2011/02/27'

日期值需要作为字符串输入。

为了确保您的SQL Server 2008及更高版本的查询能够适应未来，Date应该被转义，因为在以后的版本中它是一个保留字。

请记住，没有时间的日期将午夜作为默认值，因此这里可能没有正确的值。

我们可以使用between来显示两个日期数据，但这将搜索整个数据并进行比较，因此对于巨大的数据，它会使我们的过程变慢，所以我建议每个人都使用datediff:

qry = "SELECT * FROM [calender] WHERE datediff(day,'" & dt & "',[date])>=0 and datediff(day,'" & dt2 & "',[date])<=0 "

这里的日历是表，dt作为开始日期变量，dt2是结束日期变量。

对当前日期和前三天之间的选择日期的最佳查询:

  select Date,TotalAllowance from Calculation where EmployeeId=1 and Date BETWEEN       
DATE_SUB(CURDATE(), INTERVAL 3 DAY)  AND CURDATE() 

当前日期和未来三天之间的选择日期的最佳查询:

  select Date,TotalAllowance from Calculation where EmployeeId=1 and Date BETWEEN   
   CURDATE()  AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)
