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.

Xiaoyan

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?
