java.sql.SQLException : ORA-06550: after calling procedure from java code 异常

Question

您好，我在调用存储过程时遇到问题。当我试图从我的以下 Java 代码中调用我的过程时

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

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

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

我遇到了这个异常

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          AND tbdf.tbl_id(+) = SUBSTR(tbls.table_name,-4) AND tbdf.tbl_desc NOT LIKE '%Note: This table is obsolete%';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; 

Answer 1

错误消息指出无法找到 SCHEMA_RESTORE.RESTORE。有几种可能的原因:

• 包(和过程)在不同的模式中，例如你以用户 A 的身份编译它，但试图以用户 B 的身份调用它们。
• 您无权执行程序包中的过程。因此它变得不可见。
• 您已在包体中定义过程，但尚未在包头中声明它。

我能看到的另一个问题是括号。如果调用不带参数的过程，则应省略括号:

{ call SCHEMA_RESTORE.restore }
