Writing MySQL Node.js models using node-mysql

I'm trying to find some good practices for writing MySQL models using node-mysql.

Here's what I have so far:

var client = app.settings.client; // Client is set in Express settings

var table = 'users';

var User = function() {

}

// Create the user with data from Facebook
User.prototype.createFromFacebook = function (name, first_name, last_name, email, location, gender, facebookId, facebookToken, callback) {
  client.query(
    'INSERT INTO ' + table +
    ' SET name = ?, first_name = ?, last_name = ?, email = ?, location = ?,' +
    ' gender = ?, facebook_id = ?, facebook_token = ?',
    [ name, first_name, last_name, email, location, gender, facebookId, facebookToken ],
    function selectCb(err, results, fields) {
      if(err) {
        callback(err);
      } else {
        callback(null, results);
      }
    }
  );
}

// Get user with just their email address
User.prototype.getByEmail = function (email, callback) {
  client.query(
    'SELECT * FROM ' + table +
    ' WHERE email = ?',
    [ email ],
    function selectCb(err, results, fields) {
      if(err) {
        callback(err);
      } else {
        callback(null, results);
      }
    }
  );
}
module.exports = User;

Any critiques or improvements on this would be awesome. Thanks!
