Hi, I'm trying to use executePrepared from Phalcon\Db\Adapter\Pdo\Mysql but I have no idea what the third parameter $dataTypes is supposed to be. Documentation just ignores this third parameter but it's not optional!
public PDOStatement executePrepared (PDOStatement $statement, array $placeholders, array $dataTypes) inherited from Phalcon\Db\Adapter\Pdo
