During the trigger execution getting error : ORA-00604: error occurred at recursive SQL level 1 ORA-00900: invalid SQL statement

Question

当我尝试执行此触发器时出现以下错误：

CREATE OR REPLACE TRIGGER create_table_trigger AFTER CREATE ON SCHEMA DECLARE
    lv_sql     VARCHAR2(5000);
   obj_name   VARCHAR2(500);
BEGIN
    obj_name := sys.dictionary_obj_name;
    lv_sql := 'EXEC SYS.DBMS_FGA.add_policy (object_schema     => ''AIM_DBA'',object_name => '''|| obj_name|| ''',policy_name => ''PROTECT_'|| obj_name || ''',audit_condition  => null,audit_column => NULL,handler_schema => ''AIM_DBA'',handler_module =>''WHERE_CLAUSE_PROTECTOR_PKG.TABLE_PROTECTOR'',enable => TRUE,statement_types => ''UPDATE,DELETE'')';
    IF
        sys.dictionary_obj_type = 'TABLE'
    THEN
        dbms_output.put_line(obj_name);
        dbms_output.put_line(lv_sql);
        EXECUTE IMMEDIATE lv_sql;
        dbms_output.put_line(lv_sql);
    END IF;

END;
/

ORA-04088: 执行触发器时出错 'AIM_DBA.CREATE_TABLE_TRIGGER' ORA-00604: 递归 SQL 级别 1 发生错误 ORA-00900: 无效的 SQL 语句 ORA-06512: 在第 17 行

触发器的用途：每当用户创建 table 之后，应为此 table 启用审核。

执行错误消息：

SQL> create table aim_dba.WHERE_TST27
(
    dummy varchar2(20)
);  2    3    4
WHERE_TST27
EXEC SYS.DBMS_FGA.add_policy (object_schema     => 'AIM_DBA',object_name => 'WHERE_TST27',policy_name => 'PROTECT_WHERE_TST27',audit_condition  => null,audit_column => NULL,handler_schema =>
'AIM_DBA',handler_module =>'WHERE_CLAUSE_PROTECTOR_PKG.TABLE_PROTECTOR',enable => TRUE,statement_types => 'UPDATE,DELETE')

EXEC（或EXECUTE）是SQL*Plus 和相关客户端shorthand 的匿名块。 SQL 或 PL/SQL 引擎无法识别它。

改为使用 BEGIN/END 调用：

lv_sql := 'BEGIN SYS.DBMS_FGA.add_policy (... statement_types => ''UPDATE,DELETE''); END;';
--         ^^^^^                                                                   ^^^^^^

我不确定你为什么在这里使用动态 SQL，你可以直接调用 SYS.DBMS_FGA.add_policy。

但无论哪种方式，从您随后的 ORA-04022 错误来看，DBMS_FGA 似乎正在执行 DDL，这需要在同一 table 上进行字典锁定，因此这不会起作用.您需要重新考虑您的方法。
