Question

how can i run one query in pl-sql- in parallel?

i need all the flow…

Answer 1

You can create JOBs in order to run the same query with parallelism.

EXAMPLE

CREATE OR REPLACE PROCEDURE target_deletion
IS
   number_of_the_job   NUMBER;
BEGIN
   DBMS_JOB.submit (number_of_the_job, 'begin stored_procedure_for_deletion; end;', SYSDATE);
END;
/

EXPLAINATION

Please suppose you have, in your Oracle DataBase, a stored procedure called exactly as follows:

stored_procedure_for_deletion

If you wish to execute that stored procedure many times with PARALLELISM, you have to create a stored procedure called for example “TARGET_DELETION” (written above), which creates a new job that invokes, with the PL/SQL block:

begin stored_procedure_for_deletion; end;

… the execution of your procedure called “stored_procedure_for_deletion”.

The job starts immediately, so you can run the stored procedure target_deletion many consecutive times, in order to run the same procedure with parallelism.
