31-mysql 代码建立数据库

给个例子，模仿即可：

drop database if exists tt;
create database tt default character set utf8;
 
use tt;
 
create table admin_tb(
	id int(11) auto_increment primary key,
	username varchar(20) not null unique,
	password varchar(20) not null,
	name varchar(10) not null,
	createtime timestamp default current_timestamp
)engine=InnoDB auto_increment=1 default charset=utf8;
INSERT INTO admin_tb (username,password,name) VALUES ('xx','xx','xx');
 
create table user_tb(
	id int(11) auto_increment primary key,
	username varchar(20) not null unique,
	password varchar(20) not null,
	name varchar(20) not null,
	nicknamek varchar(20),
	sex varchar(1) check(sex='男' or sex='女'),
	birth date,
	phone varchar(15),
	qq varchar(11),
	integral int(5) default 5,
	signature varchar(200),
	avater varchar(200),  /*头像*/
	status int(2) default 1,
	createtime timestamp default current_timestamp
)engine=InnoDB auto_increment=1 default charset=utf8;
INSERT INTO user_tb (username,password,name,nicknamek,sex,birth,phone,qq,integral,signature)
	VALUES ('xx','xx','xx','xx','m','1996-7-27','33','33','5','from xx');
INSERT INTO user_tb (username,password,name,nicknamek,sex,birth,phone,qq,integral,signature)
	VALUES ('xx','xx','xx','xx','m','1996-7-27','333','33','5','from xx');
