错误:PLS-00103:遇到以下其中一项时遇到符号“END”

我编写了以下Package and Package主体:

create or replace package discounts
is
g_id number := 7839;
discount_rate number := 0.0;
procedure display_price(p_price number);
end;
/
create or replace package body discounts
is
procedure display_price(p_price number)
is
  begin
     dbms_output.put_line('Discount rate 1:'||discount_rate); 
     dbms_output.put_line('Discounted '||to_char(p_price * nvl(discount_rate,0)));
     dbms_output.put_line('Discount rate 2:'||discount_rate); 
  end;
begin
  dbms_output.put_line('Discount rate 3:'||discount_rate); 
  discount_rate := 0.10;
  dbms_output.put_line('Discount rate 4:'||discount_rate); 
end;
/

写入“在会话中第一次调用包时,discount_rate的值设置为0.10”。我没有明白这一点,这就是为什么我每次检查贴现率的价值。我输入以下内容来调用:

SQL> execute discounts.display_price(1000);
Discount rate 3:0
Discount rate 4:.1
Discount rate 1:.1
Discounted 100
Discount rate 2:.1

然后我再次调用变量:

  begin
    dbms_output.put_line('Discount rate :'||discounts.discount_rate);
  end;
  SQL> /
  Discount rate :.1

然后我输入“exit”来关闭SQL * PLUS。我再次打开SQL * PLUS并输入相同的代码:

  begin
    dbms_output.put_line('Discount rate :'||discounts.discount_rate);
  end;

我认为它不会初始化变量,但我得到了错误:

  ERROR at line 3:
  ORA-06550: line 3, column 1:
  PLS-00103: Encountered the symbol "END" when expecting one of the following:
  := . ( % ;
  The symbol ";" was substituted for "END" to continue.

错误是什么?我是PL / SQL准备认证考试的新手。
