SQL查询以选择两个日期之间的日期
问题描述:
我有一个开始日期
和结束日期
。我想获取这两个日期之间的日期列表。谁能帮助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。
答
您应该将这两个日期放在单引号之间。
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'
或可以使用
select Date, TotalAllowance from Calculation where EmployeeId = 1
and Date >= '2011/02/25' and Date <= '2011/02/27'
保持请记住,第一个日期是包含日期,但第二个日期是排除日期,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'
