Packages oracle not recognized lexical parameter that passed from BIP

Question

Dear all,
My name is Rizal, i've a problem when passing lexical parameter from BIP to Oracle Packages. Below is my data template in BI Publisher that call function f_where_clause on packages :
<dataTemplate name="dtTemplate1" description="dtTemplateTest" dataSourceRef="prodin" defaultPackage="pkg_rep_bip">
<dataTrigger name="cobaTrigReport" source="pkg_rep_bip.f_where_clause(:P_SD)"/>
<dataQuery>
<sqlstatement name="Q1">
<![CDATA[SELECT CODE, SPPD_CODE FROM PRO_SPD01 &amp;v_where_clause]]>
</sqlstatement>
</dataQuery>
</dataTemplate>
and P_SD is one parameter that i created in BI Publisher.
and below is my packages (Spec and Body) :
SPEC :
CREATE OR REPLACE package PRODIN.pkg_rep_bip
as
v_where_clause varchar2(10000);
function f_where_clause (p_sd varchar2)return boolean;
end pkg_rep_bip;
BODY :
CREATE OR REPLACE package body PRODIN.pkg_rep_bip as
function f_where_clause (p_sd varchar2)return boolean is
begin
if p_sd = 'Y' then
v_where_clause := ' where re=11';
else
v_where_clause := ' where re=24';
end if;
return true;
end f_where_clause;
end;
More detail problem is when parameter P_SD = Y (i assigned in BI PUblisher) the result always go to (v_where_clause := ' where re=24'). Any help/answer really appreciate.. Many thanks..

Answer 1

It seems that Reports help is wrong ( or imprecise).
Eg. if we have:
select &p_select
  from dept
where &p_where
and the initial values for the parameters are:
p_select: deptno, dname
p_where: 1 = 2
and the code in the Before Reports trigger is the following:
function BeforeReport return boolean is
begin
  :p_select := 'deptno, ''abcde'' ';
  :p_where := '1 = 1';
  return (TRUE);
end;
we get all the rows (where 1 = 1) and we get the value 'abcde' in the field "dname".
However, try to move your code from the Before Report trigger to After Parameter Form trigger.
