I have a database that displays a list of items. doctrine/dbal decided to split execute() into executeQuery() and executeStatement() for doctrine/dbal:^3. To differentiate between select and manipulation queries, the Statement should differentiate using two methods executeQuery() which returns a Result and executeStatement which returns the number of affected rows. awesome! We get a Doctrine\DBAL\Connection object. This acts as a wrapper around PHP's native PDO and adds some features on top of it.
