Use a package function inside a select of the same package

Question

Hi.
How can i use a function defined inside a package, with a select used inside that same package ?
Example
... package example
CREATE OR REPLACE PACKAGE BODY pkg_example
AS
     FUNCTION sum_two_values(p_val1 NUMBER,p_val2 NUMBER) RETURN NUMBER
     IS
     BEGIN
     RETURN p_val1 + p_val2;
     END sum_two_values;
     FUNCTION use_another_function_example RETURN VARCHAR2
     IS
     v_value NUMBER;
     BEGIN
     SELECT sum_two_values(2,2) INTO v_value FROM dual;
     RETURN 'waaaazzzzupppppp'
     END use_another_function_example;
END pkg_example;
This will not work
-- SELECT sum_two_values(2,2) INTO v_value FROM dual;
How can i call a function inside a select statement, a function of the same package where the query is being called.
(i have Oracle 9.2x)
Cheers.

Answer 1

are you sure? you are not using package1, you are using pack1
SQL> CREATE OR REPLACE PACKAGE package1
  2  IS
  3     FUNCTION f1
  4        RETURN NUMBER;
  5 
  6     FUNCTION f2
  7        RETURN NUMBER;
  8  END;
  9  /
Package created.
SQL> CREATE OR REPLACE PACKAGE BODY package1
  2  IS
  3     a   NUMBER;
  4 
  5     FUNCTION f1
  6        RETURN NUMBER
  7     IS
  8     BEGIN
  9        RETURN 1;
10     END;
11 
12     FUNCTION f2
13        RETURN NUMBER
14     IS
15     BEGIN
16        SELECT package1.f1
17          INTO a
18          FROM DUAL;
19 
20        RETURN a;
21     END;
22  END;
23  /
Package body created.
Why not just this
SQL> ed
Wrote file afiedt.buf
  1  CREATE OR REPLACE PACKAGE BODY package1
  2  IS
  3     a   NUMBER;
  4     FUNCTION f1
  5        RETURN NUMBER
  6     IS
  7     BEGIN
  8        RETURN 1;
  9     END;
10     FUNCTION f2
11        RETURN NUMBER
12     IS
13     BEGIN
14        a:= f1;
15 RETURN a;
16     END;
17* END;
