In MySQL, a trigger is associated with exactly one table. It cannot be associated with multiple tables. Therefore, a trigger must be defined for each table where you want similar actions to be taken in response to events like INSERT, UPDATE, or DELETE[1][3][4][5].
Regarding the association of triggers with views, MySQL does not allow triggers to be directly associated with views. Triggers can only be associated with base tables. However, operations performed on updatable views that modify the underlying base tables can indirectly activate triggers associated with those base tables[1][3].
