Triggers recursive call

        Hi to all,

        Does anybody know how setup the database to avoid any trigger recursive call?

	Look at this dummy example:
	Trigger is "statement" related type trigger (not of "for each row"
type).
	If I run the below using "for each row" clause I get mutating error.

	create or replace trigger tr_booking after update on booking
	declare
	  cont number;
	begin


	  ...

	  update booking set col1 = col1 + 10 where col2 = 'A';


	  ...

	end;
	/
