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 Date BETWEEN to_date('2011/02/25','yyyy-mm-dd') 
               AND to_date ('2011/02/27','yyyy-mm-dd');

select * from test 
     where CAST(AddTime as datetime) between '2013/4/4' and '2014/4/4'

——如果数据类型不同

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' 

该查询适用于获取当前日期和接下来3个日期之间的值

SELECT * FROM tableName  WHERE columName 
BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)

这最终将为当前日期增加额外3天的缓冲时间。
