用于选择两个日期之间的日期的 SQL 查询

SQL query to select dates between two dates(用于选择两个日期之间的日期的 SQL 查询)

问题描述

我有一个 start_date 和 end_date.我想获取这两个日期之间的日期列表.谁能帮我指出查询中的错误.

I have a start_date and end_date. I want to get the list of dates in between these two dates. Can anyone help me pointing the mistake in my query.

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

这里的 Date 是一个 datetime 变量.

Here Date is a datetime variable.

推荐答案

你应该把这两个日期放在单引号之间，比如..

you should put those two dates between single quotes like..

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，第一个日期是包含的，但第二个是不包含的，因为它实际上是2011/02/27 00:00:00"

keep in mind that the first date is inclusive, but the second is exclusive, as it effectively is '2011/02/27 00:00:00'
