ORA-25471: attribute name not specified for variable: string ORACLE 报错 故障修复 远程处理

文档解释

ORA-25471: attribute name not specified for variable: string

Cause: An attempt to evaluate was made, which failed because one of the attribute values for the specified variable had a NULL attribute name.

Action: Check the list of attribute values, and try again with a valid attribute name.

ORA-25471：当程序调用 DBMS_SESSION.SET_IDENTIFIER() 函数，但没有指定变量名称时，会出现ORA-25471 错误。

官方解释

Cause: DBMS_SESSION.SET_IDENTIFIER call was made without the 2nd argument (the attribute name).

Action: Make sure the 2nd argument is specified to the DBMS_SESSION.SET_IDENTIFIER call.

常见案例

比如代码如下：

DECLARE

v_val1 VARCHAR2(100);

BEGIN

v_val1 := ‘value1’;

DBMS_SESSION.SET_IDENTIFIER(v_val1);

END;

调用了DBMS_SESSION.SET_IDENTIFIER()函数，但没有给它设置变量名，会导致ORA-25471错误。

一般处理方法及步骤

1. 修改程序代码，设置正确变量名。

例如修改上述代码为：

DECLARE

v_val1 VARCHAR2(100);

BEGIN

v_val1 := ‘value1’;

DBMS_SESSION.SET_IDENTIFIER(v_val1, ‘val1’);

END;

2. 重新编译程序，重新执行。
