могу ли я как нибудь написать типа: create trigger MyTable_BU before update on MyTable for each row begin update MyTable set Count_of_child=Count_of_child+1 where ID=new.parent_id; update MyTable set Count_of_child=Count_of_child-1 where ID=old.parent_id; end; то есть если я хочу при изменении записи проделать ряд операций могу ли я использовать begin ... end ... |
