Run 2 queries at the same time on Oracle SQL Developer?

Question

I need to retrieve quite a bit of data from our oracle DB and to do so I need to run 20+ queries. Is there any way to run more than one query at a time on the same connectio

Assuming you like to live dangerously, you can run multiple "threads" from one script using the pragma AUTONOMOUS_TRANSACTION. For example:

DECLARE
   PROCEDURE foo(i IN PLS_INTEGER) AS
      PRAGMA AUTONOMOUS_TRANSACTION;
   BEGIN
      INSERT INTO qux
         SELECT * FROM bar
         WHERE baz = i;
      COMMIT;
   EXCEPTION WHEN OTHERS THEN ROLLBACK;
   END;
BEGIN
   foo(1);
   foo(2);
   foo(3);
END;
