How can I handle multiple Queries in single Report?

Question

Using Reports 6.0, i have 2 queries Q_1, Q_2 and I have define a user parameter, Flag_1 char(1).
I wish to execute Q_1 if Flag_1 = 'T' and Q_2 if flag_1 = 'F'
How can i do this?

Hello Fayad,
Another way in which you can achieve the same result in one report is by framing your two queries something like:
Q_1. select * from emp where :flag_1 = 'T'
Q_2. select * from dept where :flag_2 = 'F'.
This will cause the appropriate query to be executed, depending on the value of the flag_1 parameter. Additionally, you would need to create two report blocks in your layout, one for each of the above queries. You can create format triggers for the enclosing frame of these blocks, which will show/hide the entire block depending on the value of the flag_1 parameter. For example, the format trigger for the EMP report block (based on query Q_1) frame would look like:
function M_G_EMPNO_GRPFRFormatTrigger return boolean is
begin
if (:p_1 = 10) then
return (TRUE);
else
     return (FALSE);
end if;
end;
