->fetchSingle(); // Returns single value

$result = $dbManager->table('users')->select('id')->where(...)->fetchSingle(); // Returns 'id'
$result = $dbManager->table('users')->select('id, name, phone')->where(...)->fetchSingle(); // Returns 'id'
$result = $dbManager->table('users')->select('id, name, phone')->where(...)->fetchSingle(1); // Returns 'name'

- *If the limit is exausted, first cached result is removed and results shifted.*
- *Cashing is effective for tables with many records.*

$dbManager->beginTransaction();

try {
   $id = $dbManager->table('users')->insert(['name' => 'Karl', 'email' => 'karl@example.com'])->getId();
   $dbManager->table('orders')->insert(['user_id' => $id, 'price' => 1000, 'currency' => 'CZK', 'date%sql' => 'NOW()']);
