java.sql.SQLException:ORA-06550:从Java代码调用过程之后 [英] java.sql.SQLException: ORA-06550: after calling procedure from java code

问题描述

我在调用存储过程时遇到问题. 当我尝试从下面的Java代码中调用过程时

Hi I have problem with calling store procedure. when i am trying to call my procedure from my following java code

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

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

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

我收到此异常

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:

我的程序是

CREATE OR REPLACE PACKAGE BODY SCHEMA_RESTORE IS 
  PROCEDURE backup (pbRecreateBackupTable IN BOOLEAN DEFAULT FALSE)
    IS
      TableAlreadyExists EXCEPTION;
      PRAGMA EXCEPTION_INIT (TableAlreadyExists, -955);
      nCount NUMBER;
      CURSOR cTables IS SELECT tbls.table_name tbl, SUBSTR(tbls.table_name,4) name FROM user_tables tbls, FT_T_TBDF tbdf
        WHERE tbls.table_name NOT LIKE gsPrefix || '%' AND tbls.table_name NOT LIKE 'FT_CFG%' AND tbls.table_name NOT IN ('FT_WF_APEV','FT_WF_WFTJ','FT_WF_WFTN','FT_WF_WFNP','FT_WF_WFNV','FT_WF_WFIO','FT_WF_WFGV','FT_WF_WFND','FT_WF_WFDF','EXCEPTIONS','TESTDSFP') and tbls.table_name NOT LIKE 'FT_LOG%'
          AND tbdf.tbl_id(+) = SUBSTR(tbls.table_name,-4) AND tbdf.tbl_desc NOT LIKE '%Note: This table is obsolete%';
BEGIN

        RAISE;
    END;
  END LOOP; 
EXCEPTION
  WHEN OTHERS THEN
    RAISE;
END backup; 

推荐答案

错误消息指出找不到SCHEMA_RESTORE.RESTORE.有几种可能的原因:

The error message says that SCHEMA_RESTORE.RESTORE cannot be found. There are several possible causes:

• 程序包(和过程)处于不同的架构，例如您以用户A的身份对其进行了编译，但正尝试以用户B的身份对其进行调用.
• 您无权执行该程序包中的过程.因此它变得不可见.
• 您已在程序包主体中定义了该过程，但尚未在程序包头中声明它.

我可以看到的另一个问题是括号.如果您调用不带参数的过程，则应忽略假义:

A further problem I can see are the parentheses. If you call a procedure without arguments, the prentheses shoul be omitted:

{ call SCHEMA_RESTORE.restore }
