MySQL建表语句怎么出错了？

 CREATE TABLE posts 
(post_id    int(8) unsigned NOT NULL AUTO_INCREMENT,PRIMARY KEY(post_id),
post_user_id    int(8) unsigned,
post_date   int(10) unsigned,
post_url    varchar(100),
post_title  varchar(100),
post_end_date   int(10) unsigned,
post_slogan varchar(10),
post_content    varchar,
post_status     char(1))

倒数第二个字段 没有给长度 改成post_content varchar(10),

创建表，create table “表名”(_id intencer primary key aotoincrement not null,name varchar(20),age varchar(10));
