Re: Update trigger, please HELP!

Generic solution
create a package, holding a table with rowid's or primary keys before insert on statement level, reset the table after insert row, capture the rowid of primary key in the table, adding an element for each row
after insert on statement level: update the other rows based on the array. A few months ago Thomas Kyte posted a complete example.
