Question

我无法弄清楚我的桌子有什么问题..

CREATE TABLE PLAYER
    (FirstName          VARCHAR(15)         NOT NULL, 
    LastName            VARCHAR(15)         NOT NULL, 
    BirthDate           DATE, 
    Address             VARCHAR(30),
    EmailAddress        VARCHAR(30)         NOT NULL,
    Sex                 CHAR,
    TeamName            VARCHAR(30)         NOT NULL,
    ClubName            VARCHAR(30)         NOT NULL,
    AgeGroup            VARCHAR(5)          NOT NULL,
    PRIMARY KEY (LastName), 
    FOREIGN KEY (TeamName)
    **);**

CREATE TABLE TEAMS
    (TeamName           VARCHAR(30)         NOT NULL,
    AgeGroup            VARCHAR(5)          NOT NULL,
    Sex                 CHAR,
    CoachFName          VARCHAR(20)         NOT NULL,
    CoachLName          VARCHAR(20),
    ClubName            VARCHAR(30)         NOT NULL,   
    PRIMARY KEY (TeamName),
    FOREIGN KEY (AgeGroup)
    **FOREIGN KEY (ClubName)** 
    );

以下是我一直收到的消息..老实说，我不知道如何让这个表执行！我用粗体突出显示消息说错误就在附近。

*Msg 102, Level 15, State 1, Line 13
Incorrect syntax near ')'.
Msg 156, Level 15, State 1, Line 24
Incorrect syntax near the keyword 'FOREIGN'.*

Answer 1

您需要指定外键引用的表和字段。例如，对于第一个错误，您需要指定foreign key (teamname) references teams(teamname)，如果这是您的意思。
