Re: help about ora_sql_txt(sql_text)

Hi,
  Thank you very much,but the trigger you offered still does not work,i can not 
capture the dml statment because I always get the exception,I think may this is 
because the value of ora_sql_txt(sql_text) is null which raise the exception? 
Any other suggestion?My envirment is Windows XP+ Oracle10.2

  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?

  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;

    How to get the sql text when a user executes a dml statment? I wrote a

        WHEN OTHERS THEN  
           RAISE_APPLICATION_ERROR(-20333,'There is exception!' );
    end test;

      but when a user executes a insert on test.t,there is a exception,and 
through a 
dbms_output.put_line('ora_sql_txt(sql_text)is'||ora_sql_txt(sql_text)) I found 
the value of ora_sql_txt(sql_text) is null,then how can I get a dml text?
