Answer 1

Hi ,
you are concatenating employee number ( which i would assume it is your primary key ) with employee name that most probably would be null ...
there are several solutions to this , one would be to run the query while employee name is not null
example :
Select *
From Emp
Where Ename IS NOT NULL;
Hope this helps out ...
