   ->executeRows();
 
// Get a single user
$user = db()->select('*')->from(':user')->where(['user_id' => 1])->executeRow();
 
// 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();
