Dear All,
I have two tables T1 and T2.
T1 has these columns: userid, password (userid is primary key)
T2 has these columns: sessionid, userid, logintime, logofftime
(sessionid is primary key)
I wish to add one column in T1 called last_login_time.
I want to populate this new column with max(logintime) from T2 for each
user. How do I do this? I tried variants of this:
update T1, T2 set last_login_time = max(logintime) where T1.userid =
T2.userid.
Thanks
Ravi.
