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

——如果数据类型不同

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');

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。

我会选择

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

逻辑是>=包括整个开始日期，<不包括结束日期，因此我们在结束日期上添加一个单位。这可以适应几个月，例如:

select Date, ... from ...
             where Date >= $start_month_day_1 and Date < DATEADD(m, 1, $end_month_day_1)

你可以试试这个SQL

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

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)
