如何在nodejs node MYSQL中关闭与MYSQL的连接

似乎有时与MYSQL的连接没有成功关闭。我正在使用nodejs和nodemysql库

client = mysql.createClient({ user: 'root', password: 'pass' });
client.query('USE db');
client.query( 'SELECT a FROM b ORDER BY c ASC', function selectCb(err, results, fields) {
  client.end();
  if (err) throw err;
  ....       
});

希望有帮助

client.end(function(err) {
    // do what you want after the connection if closed :)
});
