Oracle APEX PL/SQL reports

Question

Hello
I was wondering if someone can help me with the syntax error, or if someone can give an example how to implement dynamic query based on a select list item.
Last night I was looking how to implement simple PL/SQL report using Oracle Apex source region, but every time I try to run the page I'm getting an error "Flow=128 page=10 ORA-20001: wwv_flow_flash_chart.func_ret_sql_qry_err"
IF I put the same query into SQL developer and replace :P10_STATUS into string 'open', query returns correct results.
It works fine for single table, but not for inner joint.
Any help would be appreciated.
======================================================
declare
v_return varchar2(3000);
begin
IF :P10_STATUS is not null THEN
v_return := 'select p.priority, p.status, i.departments
from help_details p, help_department i
where status = :P10_STATUS';
END IF;
return v_return;
END;
=========================================================

Hi ATD,
Thanks for the suggestions.
Now i have replaced the code as
Declare
v_return varchar2(3000);
begin
     :P1_ITEM1:=:P1_DEPTLOV;
IF :P1_DEPTLOV IS NOT NULL
THEN
v_return:='select dname,deptno from dept ';
return v_return;
ELSE
V_RETURN:='SELECT ename,deptno FROM EMP ';
return v_return;
END IF;
plsql reportEdit      
report error:
ORA-20001: Error fetching column value: ORA-01403: no data found
DEPTNO     Ename
and in case i change
select dname from dept ; for select dname ,deptno from dept ;
then i m able to see only the col deptno , but in query i never used dept...
I am unable to get where is the mistake ..
Kindly to a favour by using the above link & checking the application .
