Dúvida na execução package no SQL Plus

[chduarteParticipante]

Adaptado para reduzir a quantidade de parametros:

CREATE OR REPLACE PACKAGE PKG_BUSCA IS

TYPE CURSOR_TYPE IS REF CURSOR;
TYPE ERROR_TYPE IS RECORD(
COD_ERRO NUMBER(3),
MSG_ERRO VARCHAR2(100)
);

PROCEDURE P_BUSCAR(
p_NR_CNPJ IN number,
p_RESULT OUT CURSOR_TYPE);

END PKG_BUSCA;
/

CREATE OR REPLACE PACKAGE body PKG_BUSCA IS

PROCEDURE P_BUSCAR(
p_NR_CNPJ IN number,
p_RESULT OUT CURSOR_TYPE)
as
begin
open p_RESULT for ‘select user from dual’;
end;

END PKG_BUSCA;
/

variable crs refcursor
exec PKG_BUSCA.P_BUSCAR(0,:crs);
print :crs

Tudo isso deve ser executado no SQL*Plus
