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**

如果日期在24小时内，从早上开始，到晚上结束，应该添加如下内容:

declare @Approval_date datetime
set @Approval_date =getdate()
Approval_date between @Approval_date +' 00:00:00.000' and @Approval_date +' 23:59:59.999'

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

你可以试试这个SQL

select * from employee where rec_date between '2017-09-01' and '2017-09-11' 

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

select * from table_name where col_Date between '2011/02/25' 
AND DATEADD(s,-1,DATEADD(d,1,'2011/02/27'))

这里，首先向当前的endDate添加一天，它将是2011-02-28 00:00:00，然后减去一秒，使结束日期为2011-02-27 23:59:59。通过这样做，您可以获得给定间隔之间的所有日期。

output:
2011/02/25
2011/02/26
2011/02/27
