SQL Plus过程错误

Question

我正在尝试创建一个程序，如果条件满足，它会模糊一些信息。 我能够创建程序，但执行不起作用！

这是表：

drop table orders;
create table Orders(
OrderID        number,
Firstname        varchar2(10),
State            varchar2(2),
ProductDescription    varchar2(20),
Qty            number,
ItemPrice        number);

insert into Orders values(1, 'Inaae', 'Kim','IL','hard drive', 2,200);
insert into Orders values(3, 'Lisa','Simpson','CA','Books',5,25);
insert into Orders values(4, 'Bart','Simpson','MD','Video',20,3);
insert into Orders values(5, 'Inaae','Kim','WA','ear ring',3,10);
insert into Orders values(6, 'Hommer','Simpson','IN','Beer',50,2);
insert into Orders values(7, 'Marge','Simpson','FL','coffee machine',1,150);
insert into Orders values(8, 'Gerret','W','NY','Chair',1,180);

这是程序的代码：

create or replace function fn_extended_price(itemprice IN NUMBER, Qty IN NUMBER) RETURN        NUMBER
as
begin
          RETURN itemprice * Qty;
end;
/

create or replace procedure sp_order
as
cursor c_order is select OrderId, Firstname, Lastname, ProductDescription, Qty,    itemprice, State from Orders;


   order_val c_order %ROWTYPE;
   vOrder char(20); --will handle extention price blur
   vQty number;
   vItemPrice number;
   vState varchar2(2);
   begin

   FOR order_val in c_order LOOP
   vOrder := fn_extended_price(order_val.itemprice, order_val.Qty);
   vQty := order_val.Qty;
   vItemPrice := order_val.itemprice;
   vState := order_val.State;

   if vState = 'CA' OR vState = 'MD' OR vState = 'IL' THEN
      vOrder :='*********';
      vQty   :='********';
      vItemPrice :='******';
   end if;

  DBMS_OUTPUT.PUT_LINE('---------------------------------');
  DBMS_OUTPUT.PUT_LINE('Order ID: ' || order_val.orderid);
  DBMS_OUTPUT.PUT_LINE('First Name: ' || order_val.firstname);
  DBMS_OUTPUT.PUT_LINE('Last Name: ' || order_val.lastname);
  DBMS_OUTPUT.PUT_LINE('Product Description: ' || order_val.ProductDescription);
  DBMS_OUTPUT.PUT_LINE('Qty: ' || order_val.Qty);
  DBMS_OUTPUT.PUT_LINE('Item Price::' || order_val.itemprice);
  DBMS_OUTPUT.PUT_LINE('Extended Price: $' || vOrder);
  END LOOP;      
 end;
 /

错误是：

SQL> exec sp_orders
BEGIN sp_orders; END;

  *
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00201: identifier 'SP_ORDERS' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

谁能告诉我这是什么错误？

谢谢

Answer 1

您已将过程命名为sp_order ，但您正在尝试运行名为sp_orders的过程。

更重要的是，您试图将******值存储在代码中的NUMBER变量中，这将产生"PL/SQL: numeric or value error%s"异常，更改您的过程如下：

create or replace procedure sp_order
as
cursor c_order is select OrderId, Firstname, Lastname, ProductDescription, Qty,    itemprice, State from Orders;


   order_val c_order %ROWTYPE;
   vOrder char(20); --will handle extention price blur
   vQty number;
   vItemPrice number;
   vState varchar2(2);
   begin

   FOR order_val in c_order LOOP
   vOrder := fn_extended_price(order_val.itemprice, order_val.Qty);
   vQty := order_val.Qty;
   vItemPrice := order_val.itemprice;
   vState := order_val.State;

   if vState = 'CA' OR vState = 'MD' OR vState = 'IL' THEN
      vOrder :='*********';
      vQty   :=NULL;
      vItemPrice :=NULL;
   end if;

  DBMS_OUTPUT.PUT_LINE('---------------------------------');
  DBMS_OUTPUT.PUT_LINE('Order ID: ' || order_val.orderid);
  DBMS_OUTPUT.PUT_LINE('First Name: ' || order_val.firstname);
  DBMS_OUTPUT.PUT_LINE('Last Name: ' || order_val.lastname);
  DBMS_OUTPUT.PUT_LINE('Product Description: ' || order_val.ProductDescription);
  DBMS_OUTPUT.PUT_LINE('Qty: ' || order_val.Qty);
  DBMS_OUTPUT.PUT_LINE('Item Price::' || order_val.itemprice);
  DBMS_OUTPUT.PUT_LINE('Extended Price: $' || vOrder);
  END LOOP;      
 end;
