.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

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'
