Need help with a query again

Hi Experts,

I have this query.

SELECT U.UserID,ltrim(rtrim(upper(U.UserFirstName))) + ' ' +
ltrim(rtrim(upper(U.UserLastName))) as UserName,
ltrim(rtrim(U.AttendenceDay))  as AttendenceDay,
D.DayName  as AttDayName FROM USERDETAILS as U
LEFT OUTER JOIN  DAYMST As D on U.AttendenceDay = D.DayID
where U.[UserType]=1 and U.[UserActive]='Y'
and D.DayName=datename(dw,getdate())

output
------------

UserID  UserName       Attendence       AttDayName
                  Day

22      VEDANTA_THUMB           1              Monday

44      ERIC BEDOLLA          1              Monday                                            
45      AUSTIN BEESON          1              Monday                                            
46      JACOB BEGLER          1              Monday                                            
49      JEREMY BELOUSEK          1              Monday

52      CHRISTOPHER BERGER  1              Monday      


If the user name is present in another table called LOGINDETAILS then it should not be in this table


LOGINDETAILS
---------------------

UserID      StdTimeIn                          StdTimeout                 TodaysDate
      52      2016-07-01 12:46:23.430      NULL                         08082016
      38      2016-08-02 12:46:23.430      2016-08-02 12:46:23.430         08022016
      38      2016-08-03 12:46:23.430      2016-08-03 12:46:23.430         08082016
      40      2016-08-03 12:46:23.437      NULL                         08032016
      38      2016-08-04 11:16:28.927      2016-08-04 11:30:44.780         08042016
      38      2016-08-04 11:39:34.237      NULL                         08072016
      22      2016-08-08 11:34:10.847      NULL                         08082016
      38      2016-08-04 11:30:38.137      2016-08-04 11:31:18.547         08042016
      38      2016-08-04 11:34:10.847      2016-08-04 11:30:44.780         08082016      

If the UserID has a StdTimeIn and  StdTimeout is null then I do not want that record in the first table. For example:- UserID 52 and 22 has StdTimeIn but no StdTimeout .  So I do not want that record. Please help.

Thanks in advance.
