Pdo V2.0 Extended Features

This eliminates the need for manual savepoint SQL and makes nested transaction logic error-proof.

// PDO v2.0 – FETCH_TYPED preserves SQL types $stmt = $pdo->query("SELECT id, price, is_active FROM products"); $row = $stmt->fetch(PDO::FETCH_TYPED); // $row['id'] = 5 (int), $row['price'] = 19.99 (float), $row['is_active'] = true (bool) pdo v2.0 extended features

Or using generator-based coroutines:

$stmt = $pdo->prepare("SELECT * FROM huge_table", [ PDO::ATTR_CURSOR => PDO::CURSOR_SCROLL ]); $stmt->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY, false); // For MySQL $stmt->execute(); This eliminates the need for manual savepoint SQL

: Support for ATTR_USE_UTF , ATTR_STRICT_MODE , and ATTR_TIME_ZONE . Automatic Exceptions : Enabling error generation by default. is_active FROM products")

PDO v2.0 adds a fluent batch interface:

try $pdo->exec("INSERT INTO users (id) VALUES ('abc')"); catch (PDOException $e) $ext = $pdo->getExtendedInfo(); // Returns: ['query' => 'INSERT...', 'params' => [], 'affected_rows' => 0, 'driver_error_detail' => ...] logError($ext);
