mysql错误1064找不到错误

我在“外键zip”附近找不到错误， 也不知道为什么它不能创建订单和详细信息， 我怀疑这与primarykey由 两个外键

CREATE TABLE zipcodes
    (zip            NUMERIC(5,0), 
     city       VARCHAR(20),

     PRIMARY KEY (zip)

    ) ENGINE = InnoDB;

CREATE TABLE employees
    (eno        VARCHAR(10),
     ename      VARCHAR(20),
     zip        NUMERIC(5,0),
    hdate     date, 
     PRIMARY KEY (eno,
     FOREIGN KEY (zip) REFERENCES zipcodes (zip)

主键eno，丢失？在employee table上这两行主键eno，外键zip引用zipcodes zip在eno之后似乎有一个缺失。哇，我是个白痴，我已经在这里主演了几个小时了，谢谢XQbert不是白痴，只是有时候会忽略和“新眼睛”的帮助。
