Hi here is the Data type of the columns i am selecting.. and the result i am getting. 
But here the total_login_time is wrong. .
I need difference between last 2 logins not length of the session.

It is unclear what you are trying to achieve... 
DATEDIFF(d,Logindate,Logindate2)
AS [Login difference]
FROM.....
