請(qǐng)問(wèn)怎么設(shè)置多個(gè)限制策略？
CREATE TABLE Employee(
? ? Eno char(4) CONSTRAINT PK_employee PRIMARY KEY,
? ? Name varchar(8),
? ? Sex char(2),
? ? Age int CHECK(Age<= 60 AND Age >= 18),
? ? Dno char(2) CONSTRAINT FK_employee REFERENCES Department(Dno)
? ? ON DELETE CASCADE?
? ? ON UPDATE CASCADE
);
最后一行會(huì)報(bào)錯(cuò)說(shuō)缺少右括號(hào)，請(qǐng)問(wèn)是怎么回事呢？
