Mysql创建数据表报错，望指点迷津

mysql> create table caseinfo(
    -> caseid char(20) primary key,
    -> name char(20) not null,
    -> sex char(2) not null,
    -> age int not null,
    -> abte char(10),
    -> userid char(10),
    -> condition nvarchar(500),
    -> physics nvarchar(200),
    -> recipe nvarchar(500),
    -> cnum int not null,
    -> items nvarchar(200)
    -> )
    -> ;
