我喜欢使用1 MonthName 2015语法来表示日期:

   WHERE aa.AuditDate>='1 September 2015'
     AND aa.AuditDate<='30 September 2015'

对日期

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**

SELECT Date, TotalAllowance  
FROM Calculation  
WHERE EmployeeId = 1 
  AND Date BETWEEN to_date('2011/02/25','yyyy-mm-dd') 
               AND to_date ('2011/02/27','yyyy-mm-dd');

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)   

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。

由于没有指定时间段的datetime将具有date 00:00:00.000的值，如果您希望确保获得范围内的所有日期，则必须为结束日期提供时间，或者增加结束日期并使用<。

select Date,TotalAllowance from Calculation where EmployeeId=1 
and Date between '2011/02/25' and '2011/02/27 23:59:59.999'

OR

select Date,TotalAllowance from Calculation where EmployeeId=1 
and Date >= '2011/02/25' and Date < '2011/02/28'

OR

select Date,TotalAllowance from Calculation where EmployeeId=1 
and Date >= '2011/02/25' and Date <= '2011/02/27 23:59:59.999'

不要使用下面的语句，因为如果它们的时间是00:00:00.000，它可能会返回一些从2011/02/28开始的记录。

select Date,TotalAllowance from Calculation where EmployeeId=1 
and Date between '2011/02/25' and '2011/02/28'
