Проверка существования записи в таблице

Question

Правильно ли писать следующим образом, если мне нужно только убедится в существовании записи:

if (!$db->query('SELECT * FROM rubrics WHERE name = exemple')) $err[]='exemple не существует';

Ну а серьезно?!

Я чуть-чуть поправил и вот что выдал:

			// Проверка существования записей в таблице rubrics
if (!$db->query("SELECT * FROM rubrics WHERE name='exemple'")->rowCount()) $err[0][]='exemple';
// Проверка существования таблиц
if (!$db->query("SELECT * FROM exemple")) $err[1][]='exemple';

Как оно? Верно. Или можно проще да лучше?
