Row-level triggers are executed for each row affected by the triggering event, whereas statement-level triggers are executed once for each triggering event regardless of the number of rows affected. Row-level triggers have access to the specific row data being modified, making them useful for enforcing constraints or triggering actions based on individual row changes. Statement-level triggers are more efficient for bulk operations or actions that do not need to consider individual row data.
