Doctrine 2.3.4 DBAL + ORM, using Silex


In the documentation of the the ResultStatement::fetch() function says that we should use the Query::HYDRATE_* constants but that constant does not exist at least not in 2.3.4.

Should I just use PDO::FETCH_BOTH? But if I change the driver to sqlite or whatever is it going to work well?

Query constants are defined in AbstractQuery (superclass of the Query class) - see https://github.com/doctrine/doctrine2/blob/2.3.4/lib/Doctrine/ORM/AbstractQuery.php#L45-L60

Hello Marco! Thanks for your fast answer!
Some comments: The constant HYDRATE_BOTH doesn't exist, at least not with that name. Documentation should be updated too.
Another thing I'm obliged to use ORM to call a constant in DBAL? Not a problem for me because I need both

Sorry, confused this one as an ORM issue.

Checked briefly - you should indeed use the `PDO::FETCH_*` constants.

Can you link the document that contains the imprecision?

Comment by Julio Montoya [ 12/Jun/13 ]

This is the documentation in the fetch(), fetchAll() functions in DBAL:


For example, if I want to fetch an Object what should I use 1. or 2. ? I don't know if this have some implications in other drivers.

1. $statement->fetch(\Doctrine\ORM\Query::HYDRATE_OBJECT);
2. $statement->fetch(PDO::FETCH_OBJ);

An update to the documentation will be fine too:


it should be:


instead of


with a list of options (constants) ...

Working in a PR but first we need to define those constants ...

I guess this is a Doctrine 1 legacy problem. I was confused by the methods' documentation today, too. I think the documentation was copied from Doctrine 1 code and never updated. You should definitely use PDO_FETCH* constants for this as the drivers rely on this. I will PR a documentation update these days...
