Hi,
  Thank you very much,however,in Oracle 10.2,I got the ddl sql text through 
that way because the value of ora_sql_txt(sql_text)  is 1 in ddl trigger,but 
when it comes to dml statement,the value of ora_sql_txt(sql_text)  is 
null,which confused me greatly.

  It seems ora_sql_text returns null on 10g - see 
http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:1380003556171
 and other google hits.

  sorry, that doesn't really answer your question, but it does explain why you 
get no SQL...

  Cheers 

  Nigel

  How to get the sql text when a user executes a dml statment? I wrote a 
trigger like this:(a triiger on the table 'T' of schema 'TEST')

  CREATE OR REPLACE TRIGGER test
    AFTER insert ON test.t  
  declare
      sql_text ora_name_list_t; 
      state_sql dml_trace.ddl_sql%TYPE; 
  BEGIN 
         FOR i IN 1..ora_sql_txt(sql_text) LOOP 
         state_sql := state_sql||sql_text(i); 
         INSERT INTO t VALUES (i);
      END 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,state_sql); 
  EXCEPTION  
      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?
