create table ‘user‘( ‘id‘ int(10) not null, ‘username‘ varchar(20) not null, ‘password‘ varchar(20) not null, primary key (‘id‘), unique key ‘username‘);
错误原因： 去掉 单引号， 改为如下
mysql> create table user(
-> id int(10) not null,
-> username varchar(20) not null unique,
-> password varchar(20) not null,
-> primary key (id),
-> unique key ulist (username)
-> );
Query OK, 0 rows affected, 1 warning (0.32 sec)
MySql - syntax error: unexpted "user" (Single quoted text)
