五张表：

create table user(

id int auto_increment,

username varchar(50) not null,

password char(32) not null,

emailvarchar(50) not null,

address varchar(50) not null,

primary key (id),

unique (username,email)

)

create table product(

id int auto_increment,

productName varchar(100) not null,

price float not null,

producer varchar(100) default '',

primary key (id)

)

create table buy(

id int auto_increment,

userID int not null,

productID int not null,

num int not null default 1,

primary key (id),

foreign key (userID) references user(id),

foreign key (productID) references product(id)

)

create table productOrder(

id int,

productID int not null,

num int not null default 1,

primary key (id),

foreign key (productID) references product(id)

)

create table orderDetail(

orderID int not null,

userID int not null,

sendUser varchar(50) not null,

sendAddress varchar(50) not null,

buyTime int not null,

userEmail varchar(50) not null,

foreign key (orderID) references productOrder(id),

foreign key (userID) references user(id),

foreign key (sendUser) references user(username),

foreign key (sendAddress) references user(address),

foreign key (userEmail) references user(email)

)

创建oderDetail时出现error:1050的错误。经过排除是因为外键foreign key (userEmail) references user(email)和foreign key (sendAddress) references user(address)有问题。但是排查不出来，求大神帮忙！！！

外键这东西应该是其他表的主键吧？你user表有这么多主键？？

enum括号里的内容，加上引号试试 enum('0','1') enum('n','a')

错误提示了有所说明了。“……near '0,1),……”，在 0,1)附近有错。

id int primary key not null auto_increment,

name varchar(15) not null,

job tinyint not null,

level tinyint not null default 1,

cap tinyint not null,

cloth tinyint not null,
