Finding table name on which a trigger fired.

Question

I need my trigger to report the name of the table and the DML event that caused the "for each row" trigger to fire.
How do I have the trigger identify this information without hardcoding the table name and event into the trigger ?

Answer 1

Actually, I blieve that you can find the name of the trigger by looking in the call stack trace. I think I have seen code for this posted at asktom (asktom.oracle.com).
To find the triggering statement you can do the following providing you have version 9+:
set echo on
create table t ( x int );
create or replace trigger t_trigger
before insert on t
declare
l_text ora_name_list_t;
begin
dbms_output.put_line( 'The statement that caused me to fire is:' );
for i in 1 .. ora_sql_txt( l_text )
loop
dbms_output.put_line( l_text(i) );
end loop;
end;
set serveroutput on
variable n number
insert /* check this out */ into t values ( :n );
drop table t
I forgot where I stole this code from but it was probably posted on comp.databases.oracle.server or asktom.
