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

/****** Script for SelectTopNRows command from SSMS  ******/
SELECT TOP 10 [Id]
  ,[Id_parvandeh]
  ,[FirstName]
  ,[LastName]
  ,[RegDate]
  ,[Gilder]
  ,[Nationality]
  ,[Educ]
  ,[PhoneNumber]
  ,[DueInMashhad]

  ,[EzdevajDate]


  ,[MarriageStatus]
  ,[Gender]
  ,[Photo]

  ,[ModifiedOn]
  ,[CreatorIp]
   From
  [dbo].[Socials] where educ >= 3 or EzdevajDate  >= '1992/03/31' and EzdevajDate <= '2019/03/09' and MarriageStatus = 1

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'

你可以试试这个SQL

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

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**

这对我很有效

SELECT 
  * 
FROM 
  `request_logs` 
WHERE 
  created_at >= "2022-11-30 00:00:00" 
  AND created_at <= "2022-11-30 20:04:50" 
ORDER BY 
  `request_logs`.`id` DESC
