一个聊天室demo~~用的是最近出来的Jaxer1.2服务器（号称是第一个完全的Ajax服务器）～～对初学者来说是一个很不错的教程

(function() {
	
if (Jaxer.application.isInitialized) return;

var sql;

sql = "CREATE TABLE IF NOT EXISTS users " +
	"( id INTEGER PRIMARY KEY AUTO_INCREMENT" +
	", username VARCHAR(255) NOT NULL" +
	", password VARCHAR(255) NOT NULL" +
	", created DATETIME NOT NULL" +
	", last_login DATETIME NOT NULL" +
	", UNIQUE (username)" +
	")";

Jaxer.DB.execute(sql);

sql = "CREATE TABLE IF NOT EXISTS messages " +
	"( id INTEGER PRIMARY KEY AUTO_INCREMENT" +
	", room_id INTEGER NOT NULL" +
	", sent DATETIME NOT NULL" +

Jaxer.DB.execute(sql);
