Re: help about ora_sql_txt(sql_text)

I'm not sure what you're attempting to do with that first loop, but both it and the state_sql variable are unneeded.

Perhaps a perusal of the docs is in order?

http://download-west.oracle.com/docs/cd/B10501_01/appdev.920/a96590/adg14evt.htm#1000872

This trigger works:

CREATE OR REPLACE TRIGGER test
AFTER insert ON t
declare

   sql_text ora_name_list_t;
BEGIN    FOR i IN 1..ora_sql_txt(sql_text) LOOP

      INSERT INTO
dml_trace(user_name,ipaddress,audit_time,schema_user,schema_object,ddl_sql)

VALUES(sys_context('userenv','session_user'),sys_context('userenv','ip_address'),SYSDATE,

      ora_dict_obj_owner,ora_dict_obj_name,sql_text(i));    END LOOP;
EXCEPTION
   WHEN OTHERS THEN
      RAISE_APPLICATION_ERROR(-20333,'There is exception!' ); end test;
