No Column Header if 0 Child Records

Question

Hi everybody,
I have one parent qry and other child qry. e.g. in scott/tiger Dept is parent and Emp is child. I have to print all employees for a department like
Dept 01 SALES
Employee Code Name
10283 BLAKE
2304 JOHN
I want that if there is no employee for 02 'MARKETING' department then the header for employee data should not be printed. Print should be only
Dept 02 MARKETING
I do not want to use thing like a flag or dummy column. Please let me know the solution
Regards
Mona

Answer 1

try this format trigger on the enclosing fram of headings or each heading.
function M_G_EMPNO_HDRFormatTrigger return boolean is
v_count number;
begin
select count(*) into v_count
from emp
where deptno=:deptno;
if v_count >0 then
     return (TRUE);
else
return (false);
end if;
end;
