Hi
I think the following does what your require. Note changes in Capitals, and extra brackets :)
select h.fullname, s.shiftdate, p.pchin, p.pchout, s.shift_begin,
s.shift_end
from scheduled_work s
LEFT join pchup p on p.empno = s.empno
join empinfo_history h on h.empno = s.empno
where P.EMPNO IS NULL OR (
(cast(p.pchin as date) = s.shiftdate) and
((cast(p.pchin as time) > s.shift_begin) or
(cast(p.pchout as time) < s.shift_end)) )
order by s.shiftdate
