Question

嗨，我有调用存储过程的问题。当我试图从我的以下java代码中调用我的程序时

connection = ConnectionManager.getInstance().getConnection(dataBaseURL, serverName, portNumber, sid, username, password);

callable = connection.prepareCall("{call SCHEMA_RESTORE.restore()}");

callable.executeUpdate();
..................................

我收到此例外

Exception in thread "main" java.sql.SQLException: ORA-06550: line 1, column 7:

PLS-00201: identifier 'SCHEMA_RESTORE.RESTORE' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

Answer 1

错误消息显示无法找到SCHEMA_RESTORE.RESTORE。有几种可能的原因：

包（和程序）采用不同的模式，例如您将其编译为用户A，但尝试将其称为用户B.
您没有从包中执行过程的访问权限。因此它变得不可见。
您已在程序包正文中定义了该过程，但尚未在程序包标题中声明它。

我能看到的另一个问题是括号。如果你调用一个没有参数的程序，那么应该省略这些假设：

{ call SCHEMA_RESTORE.restore }

Answer 2

当您在一个用户中创建过程并将db连接到另一个用户时，就会出现这种情况。要解决此问题，请尝试此

GRANT EXECUTE ON procedureName TO username

否则请使用正确的用户名

进行连接

Answer 3

程序编译成功了吗？还要检查是否可以通过模式

下的某个编辑器（PL / SQL dev？）查看它

或者您可以使用它来查看它是否存在 -

SELECT * FROM DBA_OBJECTS WHERE object_name = '%your proc name%';
