任意有CREATE PROCEDURE权限的用户登录并且执行下列语句：

CREATE OR REPLACE PACKAGE plch_pkgIS   g_stuff   VARCHAR2 (10) := 'Stuff';   PROCEDURE show_stuff;END;/ CREATE OR REPLACE PACKAGE BODY plch_pkgIS   PROCEDURE show_stuff   IS   BEGIN      DBMS_OUTPUT.put_line (g_stuff);   END;END;/ BEGIN   plch_pkg.show_stuff;END;/ CREATE OR REPLACE PACKAGE plch_pkgIS   g_new_stuff   VARCHAR2 (10) := 'NewStuff';END;/ BEGIN   DBMS_OUTPUT.put_line (plch_pkg.g_new_stuff);END;/

下列的哪个选项正确反映了在执行上述两个匿名块之后, 我屏幕上的显示内容?

(A)
Stuff
NewStuff

(B)
First "Stuff" is displayed on the screen. Then I will see this error:
ORA-04063: package body "HR.PLCH_PKG" has errors
ORA-06508: PL/SQL: could not find program unit being called: "HR.PLCH_PKG"

(C)
Stuff

答案B
