Question

I have a query like this….

 SELECT member_Firstname, member_Lastname,
          visit_DateTime, visit_Status, visit_Logout_DateTime
          FROM members, visits
          WHERE members.member_Id = visits.member_Id
          AND members.member_Active LIKE 'y%' AND visits.visit_Status = 'accepted'  AND visits.visit_Date = '2011-11-02' Order by visit_DateTime desc limit 100;

it was giving results like this……

 firstname     lastname     status        visit_Logout_DateTime        visit_datetime      
-------------  --------      -------        ---------------------    ----------------

SELECT member_Firstname, member_Lastname,
          visit_DateTime, visit_Status, visit_Logout_DateTime
          FROM members, visits
          WHERE members.member_Id = visits.member_Id AND visits.visit_Logout_DateTime is null
          AND members.member_Active LIKE 'y%' AND visits.visit_Status = 'accepted'  AND visits.visit_Date = '2011-11-02' Order by visit_DateTime desc limit 100;

does this work?
