我正在为我的学校做一个数据库项目，我偶然发现了这个我似乎无法解决的奇怪问题。这是我尝试创建表时的代码：

PRIMARY KEY(StartDate) 
);

Create table OfferPerWeek(
StartDate       DATE            NOT NULL    ,
StartTime       TIME(0)         NOT NULL    ,
[Day]           VARCHAR(10)     NOT NULL
PRIMARY KEY (StartDate,[Day],StartTime)
FOREIGN KEY (StartDate) 
REFERENCES Offering(StartDate)
);

[Day]           VARCHAR(10)     NOT NULL    ,
StartDate       DATE            NOT NULL    , 
StartTime       TIME(0)         NOT NULL    
PRIMARY KEY (StartDate, [Day], StartTime)
FOREIGN KEY (StartDate, [Day], StartTime) 
REFERENCES OfferPerWeek (StartDate, [Day] , StartTime)
);
