Question

Example i have a stored pl/sql

isn't possible that i don't want run this execute

execute number(2);

i want run with

select * from number(2);

isn't possible to run stored pl/sql script with select statement to call the function instead of execute?

Answer 1

You can't execute a PROCEDURE from SQL; however, you can execute a FUNCTION from SQL.

First, redefine NUMBER as a FUNCTION:

CREATE OR REPLACE FUNCTION NUMBER(pTest IN NUMBER) RETURN NUMBER IS
  someValue NUMBER := pTest * 100;
BEGIN
  -- whatever
  RETURN someValue;
END;

Then execute it from a SELECT statement as

SELECT NUMBER(2) FROM DUAL;
