This is necessary because pdo_sqlsrv still has some little bugs that
prevent it from being used in all use-cases. Additionally only sqlsrv
can make use of the Azure federations features.

This enables a more natural way of interacting with result sets,

[DBAL-78] Add support for native sql list support in positional queries through the introduction of two new constants:

* Doctrine\DBAL\Connection::PARAM_STR_ARRAY
* Doctrine\DBAL\Connection::PARAM_INT_ARRAY

Replacement of arrays only works in conjunction with the Doctrine\DBAL\Connection::executeQuery() and executeUpdate() methods.
You need to pass the param constants into the third parameter called $types.
