How to set a PDO statement attribute? about db

[samdark]

Yes. You can access PDO instance via connection class.

[aliechti]

Yes but the PDO::ATTR_CURSOR attribute must be set on the pdo statement object.

Exception 'PDOException' with message 'SQLSTATE[IMSSP]: The given attribute is only supported on the PDOStatement object.'

[samdark]

Command::$pdoStatement is public.

[aliechti]

And how do I use it in my snipped?

[samdark]

Same as you'd use it with PDO.

[aliechti]

So it is not possible with the each statement?

[samdark]

Currently not.

[aliechti]

Hmm I just looked into it, but I don't know where I should put the change in.

1.Loop the Attributes through the Query

$query->setPdoAttributes([\PDO::ATTR_CURSOR => \PDO::CURSOR_FWDONLY])->each();

2.Make the method Query::createCommand return the same Command for every call, save it in a private/protected variable and just return it if called twice.

$query->command->setPdoAttributes([\PDO::ATTR_CURSOR => \PDO::CURSOR_FWDONLY]);
$query->each();

#1 looks better.
