错误: 开始低库存;结尾; * 第 1 行的错误: ORA-06550:第 1 行,第 9 列: PLS-00201:必须声明标识符“LOWINVENTORY” ORA-06550:第 1 行,第 7 列: PL/SQL:语句被忽略

表创建:
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)
);
【问题讨论】:
【参考方案1】:你的代码充满了愚蠢的错误, 首先,
select inventory.itemID, inventory.itemName,
inventory.description, inventory.startQty; --> semicolan here, the statment doesnt end
from inventory
where inventory.startQty < 5;
第二,
cursor nextItem is --> using nextItem as name in cursor but "netxtItem" while opening it, a typo
第三,
如果在 else 部分没有结束,循环
这是已经编译好的程序, 我创建了清单表,其中只有 4 列在过程中用于编译过程

【讨论】:
哇,非常感谢。如果可以的话,我会请你喝啤酒。那么我的 Oracle 帐户一定发生了一些奇怪的事情。我做了更正,我得到了同样的错误。我正在使用命令“exec LOWINVENTORY”并尝试“exec lowInventory”,它们都出现了与上述相同的错误。 能否请您发布表结构和示例数据以便我进行模拟? 我已插入样本数据,并运行了程序,请参阅输出的编辑部分以上是关于必须声明错误 PLS-00201 标识符的主要内容,如果未能解决你的问题,请参考以下文章
Oracle TYPE 声明抛出错误 PLS-00201 - 必须声明标识符
