我写了一个简单的程序尝试执行，但它显示了object_id：无效的标识符我怎么能解决 complete procedure execution image

Answer 1

参数列表/插入中的一个列名可能有误。尝试将varchar2用于所有这些，看看是否有帮助

  create or replace PROCEDURE ADD_DEPT2
                         (P_DEPTNO IN VARCHAR2,
                          P_DNAME IN VARCHAR2,
                          P_LOC IN VARCHAR2,
                          P_ERROR_MSG OUT VARCHAR2)
  IS
  BEGIN
  INSERT INTO DEPT1(DEPTNO,DNAME,LOC)VALUES(P_DEPTNO,P_DNAME,P_LOC);
  COMMIT;
  EXCEPTION
  WHEN OTHERS THEN
  P_ERROR_MSG :=SQLERRM;
  END ADD_DEPT2;

Answer 2

＆＃34;它可以显示相同的错误＆＃34;

不，不，它没有赢。让我们通过运行您发布的代码来证明这一点。

这是你的表：

SQL> CREATE TABLE DEPARTMENT(DID INT,DNAME VARCHAR2(20),DLOC VARCHAR2(20));

Table created.

SQL> INSERT INTO DEPARTMENT VALUES(101,'SRINATH','HINDUPUR'); 

1 row created.

SQL> INSERT INTO DEPARTMENT VALUES(102,'SAINATH','ANANTAPUR');

1 row created.

SQL>

以下是您的程序：

SQL> create or replace PROCEDURE ADD_DEPARTMENT
  2                      (P_DID IN DEPARTMENT.DID%TYPE,
  3                                     P_DNAME IN DEPARTMENT.DNAME%TYPE,
  4                                     P_DLOC IN DEPARTMENT.DLOC%TYPE,
  5                                     P_ERROR_MSG OUT VARCHAR2)
  6  IS
  7  BEGIN
  8     INSERT INTO DEPARTMENT(DID,DNAME,DLOC)VALUES(P_DID,P_DNAME,P_DLOC);
  9     COMMIT;
 10  EXCEPTION
 11     WHEN OTHERS THEN
 12     P_ERROR_MSG:=SQLERRM;
 13  END ADD_DEPARTMENT;
 14  /

Procedure created.

SQL>

而且！它不仅可以编译，而且运行时也没有错误。

SQL> set serveroutput on
SQL> declare                  
  2      v varchar2(128);
  3  begin
  4      add_department(666, 'Area 51', 'Roswell',  v);
  5  end;
  6  /

PL/SQL procedure successfully completed.

SQL> select * from department;

       DID DNAME                DLOC
---------- -------------------- --------------------
       101 SRINATH              HINDUPUR
       102 SAINATH              ANANTAPUR
       666 Area 51              Roswell

所以我再一次问，问题是什么？

＆＃34; PLS-00905：对象SCOTT.ADD_DEPARTMENT无效＆＃34;

在SQL * Plus中：

以SCOTT身份连接
alter procedure add_department compile;
显示错误

或者对用于编写代码的IDE应用等效序列。

执行错误时的plsql过程无效标识符00904
