获取最近30天未在sql asp.net中登录的用户

Question

I want to try get record's who not logging from last 30 days. I have try and I also got the records but, that records display from the database who logging ed before 30 days. But I want to show, who's not logging from last 30 days from current date, which I can disable them.

I try below query on sql

select distinct CmsUserLogTime.UserId  
from CmsUserLogTime 
right join CmsUser on CmsUserLogTime.UserId = CmsUser.Id
where CmsUserLogTime.LoginLogoutTime <= DateAdd(Day, -30, GetDate()) 
order by 1 asc

I just want to compare from current date to last 30 days, which I can get the records.

Thanks.

Answer 1

Using NOT IN

select 
    CmsUserLogTime.UserId  
from CmsUserLogTime 
inner join CmsUser on CmsUserLogTime.UserId = CmsUser.Id
where CmsUserLogTime.UserId in (select UserID from CmsUserLogTime group by UserID having max(LoginLogoutTime) <= dateadd(day,-30,getdate()))

Note, since you aren't returning columns from the CmsUser table, I don't see the need to JOIN to it, but left it in in case you actually do want columns from that table.

Answer 2

Use DATEADD in your WHERE clause:

...

WHERE CmsUserLogTime.LoginLogoutTime < DATEADD(day, -30, GETDATE())

You can also use abbreviation d or dd instead of day.
