錯誤必須聲明PLS-00201標識符

Question

所以我一直有這個錯誤，而且我對於發生了什麼事情一無所知。我搜索了一下，閱讀了關於這個錯誤的一些問題，並沒有任何工作。我只是想讓它運行，這樣我就可以完成我的項目。

create or replace procedure LOWINVENTORY is 

--Variables 
ID number; 
itemNamed char(15); 
description char(20); 
startQty number; 

--Define inventory item cursor 
cursor nextItem is 
select inventory.itemID, inventory.itemName, inventory.description, inventory.startQty; 
from inventory 
where inventory.startQty < 5; 

begin 
open nextItem; 
fetch netxtItem into ID, itemNamed, description, startQty; 
if nextItem%notfound then 
    dbms_output.put_line('No items in need of reordering.'); 
else 
    dbms_output.put_line('*********************'); 
    dbms_output.put_line('++Inventory Report++'); 
    dbms_output.put_line('*********************'); 
    dbms_output.put_line('Item Name---ID------Description----------Quantity'); 
    loop 
     dbms_output.put_line(itemNamed||'-'||ID||'-'||description||'-'||startQty); 
     fetch netxtItem into ID, itemNamed, description, startQty; 
     if nextItem%notfound then 
      dbms_output.put_line('************END REPORT*************'); 
      exit when nextItem%notfound; 
    end loop; 
end lowInventory; 

錯誤： BEGIN LOWINVENTORY;結束;在第1行 * ERROR： ORA-06550：第1行，第9欄： PLS-00201：標識符 'LOWINVENTORY' 必須被聲明 ORA-06550：第1行，column7： PL/SQL：語句忽略

編輯：

INSERT INTO inventory(itemID, itemLocation, itemName, description, typicalPrice, startQty) 
VALUES(24548576, 'toolbox1', 'wrench', 'turns bolts', 14.00, 6); 
INSERT INTO inventory(itemID, itemLocation, itemName, description, typicalPrice, startQty) 
VALUES(83742345, 'toolbox1', 'pliers', 'grabs stuff', 11.00, 4); 
INSERT INTO inventory(itemID, itemLocation, itemName, description, typicalPrice, startQty) 
VALUES(39287426, 'chest2', 'jigsaw', 'cuts stuff', 28.00, 3); 
INSERT INTO inventory(itemID, itemLocation, itemName, description, typicalPrice, startQty) 
VALUES(48927349, 'chest1', 'blowtorch', 'torches stuff', 330.00, 2); 
INSERT INTO inventory(itemID, itemLocation, itemName, description, typicalPrice, startQty) 
VALUES(85463455, 'bench3', 'oil filter', 'filters stuff', 16.00, 20); 

創建表：

create table inventory 
    (
     itemID number(8) not null primary key constraint lengthCHK8 check(length(itemID)=8), 
     itemLocation varchar2(10), 
     itemName varchar2(12) not null, 
     description varchar2(20), 
     typicalPrice decimal(7,2) not null constraint notNeg2 check(typicalPrice >=0), 
     startQty number(4) not null constraint notNeg5 check(startQty >=0) 
    ); 

Answer 1

你的代碼是一個充滿與愚蠢的錯誤， 首先，

select inventory.itemID, inventory.itemName, 
inventory.description, inventory.startQty; --> semicolan here, the statment doesnt end 
from inventory 
where inventory.startQty < 5; 

其次，

cursor nextItem is --> using nextItem as name in cursor but "netxtItem" while opening it, a typo 

三，

沒有結束，如果其他部分的內側，環

下面是已編譯的程序， 我創建了庫存表，只有4列用於編制程序
