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 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?
