过程给我错误：ORA-00955：现有对象已使用名称

问题描述

CREATE TABLE product
( product_id number(10) NOT NULL,product_name varchar2(50) NOT NULL,price varchar2(50)
);

CREATE OR REPLACE PROCEDURE p1 (product_id in number,product_name in varchar2,price in number) 

IS
BEGIN
INSERT INTO product values(1,'yash',100);
DBMS_OUTPUT.PUT_LINE('VALUE INSERTED');

end;

错误：ORA-00955：现有对象已使用该名称

有人可以提供我和合适的例子吗

解决方法

从错误消息中，名称p1已被使用（是其类型不同于过程的对象名称）。只需为过程指定其他名称（更具描述性！）即可：

CREATE OR REPLACE PROCEDURE insert_product 
 (product_id in number,product_name in varchar2,price in number) 

IS
BEGIN
INSERT INTO product values(1,'yash',100);
DBMS_OUTPUT.PUT_LINE('VALUE INSERTED');
END;

,

对于您的此问题，解决方案是写以下行（EXECUTE p1;） 通过键入此命令，您将获得所需的输出

,

您两次询问“合适的例子”或“证明代码”。我假设您不了解或不相信关于过程名称与其他对象名称冲突的解释。所以这是证明这一点的例子。

如果您的程序名为“ p1”，请检查：

select object_type,object_name
from user_objects
where upper(object_name) = 'P1'
;
