MySQl错误＃1064 42000

Question

I keep getting an error when creating the "orders" table. Any ideas? "customer" table already exists, as does the cust# column. Thanks in advance.

create table orders(
`order#` char(4) not null,
orderdate date not null,
`cust#` char(4) not null,
amount decimal(10,2) not null,
primary key (`order#`),
foreign key (`cust#`) references customer (`cust#`)
on delete cascade on update cascade
) engine=InnoDB; 

EDIT: simply a typo. thanks for your responses.

Answer 1

Table customer must exist before trying to create table orders .

See a demo .

While characters such as # are permitted, they should be avoided in naming objects.

Answer 2

Try adding CONSTRAINT for the foreign key.

create table orders(
`order#` char(4) not null,
orderdate date not null,
`cust#` char(4) not null,
ord_amt decimal(10,2) not null,
primary key (`order#`),
CONSTRAINT `fk_cust` foreign key (`cust#`) references customer (`cust#`)
on delete cascade on update cascade
) engine=InnoDB;
