Description:
------------
If you have a lot of queries in a script and you don't want to use the default PDO::FETCH_BOTH Mode (which returns an array with numbers and col-name indexes) - perhaps you want do use PDO::FETCH_OBJ or PDO::FETCH_ASSOC... - you have to set the fetch mode again and again for every query/statement.

If there would be something like:

PDO::setDefaultFetchMode()

or

PDO::setAttribute(PDO::DEFAULT_FETCH_MODE...)

you could set the fetch mode once in the script.
