Question

CREATE TABLE MARINA_SLIP
(
SLIP_ID VARCHAR(4),
MARINA_NUM VARCHAR(4),
SLIP_NUM VARCHAR(4),
LENGTH INT,
RENTAL_FEE DECIMAL(8,2),
BOAT_NAME VARCHAR(50),
BOAT_TYPE VARCHAR(50),
OWNER_NUM VARCHAR(4),
CONSTRAINT MARINA_SLIP_SLIP_ID_PK PRIMARY KEY (SLIP_ID),
CONSTRAINT MARINA_SLIP_MARINA_NUM_FK FOREIGN KEY (MARINA_NUM),
CONSTRAINT MARINA_SLIP_OWNER_NUM_FK FOREIGN KEY (OWNER_NUM) REFERENCES OWNER (OWNER_NUM)
);

错误说明：

错误1064（42000）：您的SQL语法有错误;检查与您的MySQL服务器版本相对应的手册，以获得正确的语法，以便在＆＃39;附近使用。 CONSTRAINT MARINA_SLIP_OWNER_NUM_FK FOREIGN KEY（OWNER_NUM）参考所有者（O＆＃39;第12行

有谁知道为什么这不起作用？

编辑：这对我来说很明显，不包括外键引用的小错误。

Answer 1

将REFERENCES添加到CONSTRAINT MARINA_SLIP_MARINA_NUM_FK FOREIGN KEY (MARINA_NUM) 例如 CONSTRAINT MARINA_SLIP_MARINA_NUM_FK FOREIGN KEY (MARINA_NUM) REFERENCES OWNER (MARINA_NUM)
