User input dependant

Question

dear
i am creaintg a report, in which i am using two parameters, one parameter is from the DB while other paramter is dependant upon user input like YES or NO. I have two queries, if user enters YES then Q_1 should be executed if user enters NO then Q_2 should be executed. How can I do this in Reports, I am using Oracle Reports 9i. I tried to user BEFORE REPORT trigger but i am unable to call the query there, please help me out in writing code.
function BeforeReport return boolean is
begin
if :OPTION='YES' then
     (Q_1 should be called here)
end if;
else if :OPTION='NO then
     (Q_2 should be called here)
return (TRUE);
end;

Thanks Marcos dear
well, i am trying to understand what you suggest but not able to understand, let me jst explain you the query. Actually I am getting two inputs from user one inut is used to build a query i mean if user inputs any data it will be in WHERE clause in my select statement.
Now other input is just to show that if user inputs YES then Q_1 should be executed, if user inputs NO then Q_2 should be executed. this 2nd input has nothing to do with the database its just YES or NO. If user enters NO then this query should be executed.
SELECT STO.STO_PART PART,PAR.PAR_DESC DESCRIPTION,'('||STO.STO_CLASS||')' CLASS,
STO.STO_MINLEV "MIN LEVEL",STO.STO_MAXQTY "MAX LEVEL",STO.STO_ORDLEV "REORDER LEVEL",
STO.STO_QTY "CURRENT QUANTITY",STO.STO_ABCCLASS "ABC CLASS",STO.STO_PREFSUP "PREFERRED SUPPLIER"
FROM R5STOCK STO,R5PARTS PAR
WHERE PAR.PAR_CODE=STO.STO_PART
AND PAR.PAR_ORG=STO.STO_PART_ORG
AND STO.STO_QTY<=STO.STO_MINLEV
AND STO.STO_STORE= :STORE
AND STO.STO_MINLEV=0
AND STO.STO_MAXQTY=0
ORDER BY STO.STO_PART
otherwise if user inputs YES then
SELECT STO.STO_PART PART,PAR.PAR_DESC DESCRIPTION,'('||STO.STO_CLASS||')' CLASS,
STO.STO_MINLEV "MIN LEVEL",STO.STO_MAXQTY "MAX LEVEL",STO.STO_ORDLEV "REORDER LEVEL",
STO.STO_QTY "CURRENT QUANTITY",STO.STO_ABCCLASS "ABC CLASS",STO.STO_PREFSUP "PREFERRED SUPPLIER"
FROM R5STOCK STO,R5PARTS PAR
WHERE PAR.PAR_CODE=STO.STO_PART
AND PAR.PAR_ORG=STO.STO_PART_ORG
AND STO.STO_QTY<=STO.STO_MINLEV
AND STO.STO_STORE= :STORE
ORDER BY STO.STO_PART
i am sure you will understand now.
