-- modify bookings - task 2
-- changes:
--   changed BookingDate (Reserved) data type from date to datetime, because I assumed that Little Lemon
--   allows wants bookings per day and table - a table is considered blocked for 2 hours
-- noqa: disable=CP03,LT02,RF03
create procedure UpdateBooking (in BookingID int, in Reserved datetime)
begin
    update Bookings as B
    set B.Reserved = Reserved
    where B.BookingID = BookingID;
    if row_count() = 1 then
      select concat("Booking ", BookingID, " updated") as Confirmation;
    else
      select concat("Booking ", BookingID, " wasn't updated - missing booking") as Confirmation;
    end if;
