try $pdo->query("SELECT invalid"); catch (PDOException $e) echo $e->getCode(); // SQLSTATE error code echo $e->errorInfo[1]; // driver-specific error echo $e->getPrevious(); // native driver exception pdo v20 extended features

V20 introduces a sub-milliamp monitoring state. This allows the system to remain "data-aware" even when the main power stage is powered down, ensuring instant wake-up cycles without losing state synchronization. Integrated Harmonic Filtering:

Scaling horizontal database architectures used to require complex user-land libraries or heavy proxy middleware like Vitess or MaxScale. PDO v20 embeds sharding awareness and high-performance connection pooling directly into the core extension. Native Connection Pooling
