$users = db()->select('*')
->from(':user')
->order('user_id ASC')
->limit(10)
->all();
// Get a single user
$user = db()->select('*')->from(':user')->where(['user_id' => 1])->get();
// Insert an entry into the DB
$insert_id = db()->insert(':user', ['user_name' => 'Foo']);
// Update an entry in the DB
db()->update(':user', ['user_name' => 'bar'], ['user_id' => 1]);
// Get the total rows
$total = db()->select('COUNT(*)')->from(':user')->count();
// Joining tables
db()->select('f.*, b.*')
->from(':foo', 'f')
->join(':bar', 'b', 'b.id = f.id')
->get();
