Answer 1

Try this

select tt.description,
       tt.visible,
       vct.currvalue 
from tblemployee tt 
  left outer join viwcurrentemployee vct 
    on vct.transitiontype = tt.cid and 
       vct.employee = 63
where tt.visible = 1 
order by tt.cid

I moved tt.visible = 1 to the where clause instead. vct.employee = 63 need to stay in the join because otherwise you would not have an outer join.

Answer 2

select tt.description,tt.visible,vct.currvalue 
from tblemployee tt 
left outer join viwcurrentemployee vct on vct.transitiontype = tt.cid
                                      and vct.employee = 63 
where tt.visible = 1 
order by tt.cid
