* This is necessary for a case where we have ambigous fields in the result.

* SELECT Child1.value, Child2.value FROM Parent LEFT JOIN Child1 LEFT JOIN Child2
* We get value twice in the result set. We want the last not empty value.
* The fetch assoc syntax does'nt work because it gives us the last value everytime, empty or not.
* The fetch num does'nt work because there is no function to retrieve the field names to create the map.
* In this approach we make use of PDO fetch class to pass the result values to an
* object and let the __set() function do the magic decision to choose the right value.
