create database if not exists OneOffWord;
(应该会失败,因为没有权限,创建失败可以去 phpMyAdmin 创建)
show databases;
use oneoffword;
create table if not exists messagedata(`id` char(5) not null, `word` varchar(10000) not null, `date` datetime not null, `timelimit` smallint not null, primary key(id)) engine=InnoDB default charset=utf8;
show tables;
select * from messagedata;
