在插入这组数据时发生了错误!!!!!!!!

FOREIGN KEY(CNO) REFERENCES Course(CNO)

你用上面这条语句在 course(cno)和sc(cno)中建立了主外键关系,sc(cno)引用了course(cno)的值,而你却先插入了sc(cno)的值!

你应试把sc和course的插值顺序倒过来!

正确代码如下:

CREATE TABLE Student

(SNO CHAR(4) NOT NULL PRIMARY KEY(SNO),

SNAME VARCHAR(20),

SEX CHAR(2) DEFAULT '男'CHECK(SEX='男' OR SEX='女'),

AGE SMALLINT CHECK(AGE>=15 AND AGE<=45),

CLASS CHAR(5))

CREATE TABLE Course

CNO CHAR(4) NOT NULL,

PRIMARY KEY(SNO,CNO),

FOREIGN KEY(CNO) REFERENCES Course(CNO))
