A table must have at least 1 column

用MySQL创建table时报错

use bbs2;

create table article{
id int primary key auto_increment,
pid int,
rootid int,
title varchar(255),
cont text,
pdate datetime,
isleaf int
};

insert into article values (null, 0, 1, '你好', '你好', now(), 1);

报错：A table must have at least 1 column

解决办法：create table article（int , text）。应该是()，而不是{};
