如何修复此错误3734：未能在MySQL WorkBench上添加外键约束？

我正在MySQL工作台上工作，不断收到错误代码3734：未能添加外键约束。此错误是什么意思？我可以修复此错误吗？我一直在别墅预订表中发现错误

     create table Reservation
(
ReservationID char(5) primary key,
ReservationDate date,
CustomerID char(5),
foreign key (CustomerID) references Customer (CustomerID)
);

create table Villa
(
VillaID char(5) primary key,
VillaName varchar(40),
VillaCostPerDay int(3), 
VillaTypeID char(5),
foreign key (VillaTypeID) references VillaType (VillaTypeID)
);

``create table VillaReservation
    (
    VillaReservationID char(5),
    VillaID char(5),
    DateFrom datetime,
    DateTo datetime,
    primary key (VillaReservationID, VillaID),
    foreign key (VillaReservationID) references Reservation(VillaReservationID),
    foreign key (VillaID) references Villa(VillaID)
    );

您引用了错误的列

引用了保留（VillaReservationID）

您已经编写了

reference

Reservation，但没有列名称

VillaReservationID

primary key (VillaReservationID, VillaID),
foreign key (VillaReservationID) references Reservation(VillaReservationID)

您可能会想到

引用Reservation（ReservationID）

即：

primary key (VillaReservationID, VillaID),
foreign key (VillaReservationID) references Reservation(ReservationID)
