i just want to generate automatically primary key values at run time...

Answer 1

you want generate the priamry key when you insert data in into table.
your v_query does it insert data, if this is the case then you can use trigger as shown below;
1. first make one sequence
2. then make one trigger
CREATE OR REPLACE TRIGGER BRI_Trig
BEFORE INSERT
ON table 1
FOR EACH ROW
DECLARE
v_id NUMBER;
BEGIN
IF :NEW.col_id IS NULL THEN
SELECT seq_name.nextval INTO v_id FROM dual;
:NEW.col_id := v_id;
END IF;
END;
