General Reporting Issue

Question

Dear Experts,
i need your advises for an issue regarding a reporting idea, i am working in Telecom company and as you know, there is alot of reports requested daily from END users, some of these reports can be moved to discoverer to let the users generate them from their side through discoverer viewer, but there are many reports still generated from my side directly from the back end (database) because they are customized for specific data sent by the end users.
for example, some users send me a list of customers numbers and they need some information for them, so i used to load them to a temp table and join it with the query to get the needed data.
i want to ask is there a way to enable the end users to get this report from their side without returning to me, that is is there any tool that let the users load some data into temp table and generate the report for that data only?
please i need ideas?

Hi,
Well all is not possible since beside the database side (the function) all other steps are configuration steps.
as for the function you can see the following as example:
create or replace function LOAD_DATA_XXXTABLE
(P_DATE_V in date) RETURN VARCHAR2
IS
PRAGMA AUTONOMOUS_TRANSACTION;
V_OUT varchar2(50);
p_date date;
v_sql varchar2(30000);
v_date varchar2(50);
v_period varchar2(50);
BEGIN
begin
p_date := (p_date_v);
v_date := ''''||to_char(p_date_v,'DD-MON-YYYY')||'''';
v_period := ''''||to_char(p_date_v,'MON-YY')||'''';
DBMS_OUTPUT.PUT_LINE('*************************************** Process Start ***************************************');
-- Truncate the table
execute IMMEDIATE 'TRUNCATE TABLE XXX.XXXTABLE';
-- Populate the table in the user partition
v_sql := '
insert into XXX.XXXTABLE
Select '||v_period||' period
from dual';
execute immediate v_sql;
commit;
DBMS_OUTPUT.PUT_LINE('End of first load: '||to_char(sysdate,'YYYY-Mon-DD HH:MI:SS'));
DBMS_OUTPUT.PUT_LINE('Table XXXXX was populated on : '||to_char(sysdate,'YYYY-Mon-DD HH:MI:SS'));
V_OUT := 'Finished OK';
RETURN V_OUT;
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line(' Error: '||substr(SQLERRM,1,250));
V_OUT := 'Finished ERROR';
RETURN V_OUT;
raise;
end;
end LOAD_DATA_XXXTABLE;
you have to build the table prior to running it !!!
insert your logic in the V_SQL variable.
if you wish to use GTT then you do not need the truncate statement...After compiling it try to run it and see if you get data, run the following:
declare
v_out varchar2(50);
begin
-- Call the function
v_out := load_data_xxxtable(p_date_v => '01-OCT-2011');
end;
then select from the table to verify it is populated:
select * from
xxx.xxxtable;
now you should register it to the discoverere administrator, after log in go to the toolbar: "tools->register PL/SQL functions"
enter the needed data (use upper case),
validate it.
then create a worksheet using Plus or Desktop, do not select any folder or any item.
create a new calculation, use the function you have just registered.
run the report and see the output, if you get OK then you can create a new worksheet that will select from your table.
Of course you need to add the table to the BA so that you will be able to use it for a report.
hope it helps
