Procedures giving error : ORA-00955: name is already used by an existing object

Question

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：名称已被现有对象使用

有人可以提供我和合适的例子吗

Answer 1

根据错误消息，名称 p1 已被使用（ 作为对象名称，其类型不同于过程 ）。只需给程序一个不同的（更具描述性的！）名称：

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;

Answer 2

对于你的这个问题，解决方案是写下一行 (EXECUTE p1;) 通过输入此命令，您将获得所需的输出

Answer 3

您已经两次要求 'suitable example' 或 'justifying code'。我假设您不理解或不相信关于您的过程名称与其他一些对象名称冲突的解释。所以这是证明它的例子。

SQL> --
SQL> -- check that we don't own anything called MYTEST
SQL> --
SQL> select object_name
  2  from user_objects
  3  where upper(object_name) = 'MYTEST'
  4  ;

no rows selected

SQL> --
SQL> -- create a table MYTEST
SQL> --
SQL> create table mytest (dob date);

Table created.

SQL> --
SQL> -- check objets
SQL> --
SQL> select object_type,
  2         object_name
  3  from user_objects
  4  where upper(object_name) = 'MYTEST'
  5  ;

OBJECT_TYPE         OBJECT_NAME
------------------- --------------------
TABLE               MYTEST

1 row selected.

SQL> --
SQL> -- create a procedure MYTEST
SQL> --
SQL> create or replace procedure mytest
  2  as
  3  begin
  4    dbms_output.put_line('Hello world');
  5  end;
  6  /
create or replace procedure mytest
*
ERROR at line 1:
ORA-00955: name is already used by an existing object


SQL> --
SQL> -- now, drop the table and try the procedure again
SQL> --
SQL> drop table mytest purge;

Table dropped.

SQL> create or replace procedure mytest
  2  as
  3  begin
  4    dbms_output.put_line('Hello world');
  5  end;
  6  /

Procedure created.

SQL> --
SQL> -- cleanup
SQL> --
SQL> drop table mytest purge;
drop table mytest purge
           *
ERROR at line 1:
ORA-00942: table or view does not exist


SQL> drop procedure mytest;

Procedure dropped.

在你的情况下，如果你的过程被命名为 'p1' 然后检查：

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