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 * 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

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');

你可以试试这个SQL

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

你应该把这两个日期放在单引号之间，比如..

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

或者可以使用

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

请记住，第一次约会包含所有内容，但第二次约会就不包含所有内容，因为它实际上是“2011/02/27 00:00:00”。
