Oracle Error PLS-00323: subprogram or cursor is declared in a package specification and must be defined in the package body

Can someone help me put my pl/sql procedure in a package? I’ve tried and I’m struggling with it:

This is what I have, for my package specification:

CREATE OR REPLACE PACKAGE film_pkg
IS
title VARCHAR2(100);
PROCEDURE get_films(fname VARCHAR2);
END film_pkg;

--

This is my package body where im running into the problems:

  CREATE OR REPLACE PACKAGE BODY film_pkg
IS
   PROCEDURE get_films (fname    IN     film.title%TYPE,
                        r_date      OUT film.release_date%TYPE,
                        dur         OUT film.duration%TYPE)
   AS
   BEGIN
      SELECT release_date, duration
        INTO r_date, dur
        FROM FILM
       WHERE title = fname;
   EXCEPTION
      WHEN NO_DATA_FOUND
      THEN
         r_date := '';
         dur := '';
   END get_films;
END film_pkg;

if anyone could help me fix the errors i’d appreciate it:

Error(4,11): PLS-00323: subprogram or cursor 'GET_FILMS' is declared in a package specification and must be defined in the package body

Answer

Your header and body procedure definitions don’t match

In the header, you have:

PROCEDURE get_films(fname VARCHAR2);

Whereas in the body:

PROCEDURE get_films(fname IN film.title%type, 
   r_date OUT film.release_date%type, dur OUT film.duration%type)

You probably just need to update the header definition with the two additional OUT params?

To Summarize

• Ensure the header definition matches all parameters of the body implementation (number of parameters, names of parameters, order of parameters, and the parameter types)
• As per Alex’s comment, do not mix and match the custom type (film.title%type) with the base type (VARCHAR2). Choose one or the other.
