oracle - DBMS_RLS.add_policy：object_name 不工作

Question

• 大家好，我正在学习 Oracle 的 VPD 功能，但我被以下代码困住了。

BEGIN
    DBMS_RLS.add_policy(
    object_schema    => 'user_bacsi_01',
    object_name      => 'HOSOBENHNHAN',
    policy_name      => 'VPD_POLICY_DOCTOR_SEE_PATIENT_INFO',
    policy_function  => 'FUNC_VPD_POLICY_DOCTOR_SEE_PATIENT_INFO'
    );
END;
/

• 错误
