Using dbms_scheduler

Question

Hi,
I need to run 50 sql statments simultaneously.
I know that i can use dbms_scheduler in order to trigger all statments in the same time.
I thought to create a procedure for each statment , and the dbms_scheduler will execute all the 50 procedures, in the very same time.
The problem is that each statment is fairly very complex , and includs joins to
few tables and selecting about 50-100 columns and if i want to put each statment in procedure
than i need to assidn a variable for each column .
Just to keep it simple , for example :
create or replace procedure test1
as
v1 date;
v2 date;
begin
select sysdate , sysdate + 1
into v1,v2
from dual;
end;
So actually , i am looking for a way to run the statments using dbms_scheduler , with no use of local variable.
Is it possible (with or without procedure) ?
Thanks

Hi,
Thank you for your feedback.
I need to run 50 sql statments simultaneously, as part of POC we are planing to take soon.
Those statments are being executing on daily basis in our DWH ETL night loading.
The execution of the statments is managed by the ETL application tool.
why? --> Its part of a POC we paln.
We would like to “stretch” the system by running those statments simultaneous
How ? -->
I thought of having a table that store those statments , then for each statment to create a job
as describe bellow :
CREATE OR REPLACE PROCEDURE POC
as
cursor c is
select id,name
from poc_statments;
Begin
for c_rec in c loop
BEGIN
DBMS_SCHEDULER.create_job (
job_name => 'POC_'||c_rec.name,
job_type => 'PLSQL_BLOCK',
job_action => 'BEGIN ?????? ; END;', <<<<=== problem is here as i expalined above
start_date => SYSTIMESTAMP,
enabled => true,
auto_drop => false);
END;
end loop;
end;
This way all the statments will executed , almost , at the sime time.
Thanks
