In fact, it works! In GSG Helen *suggested* to keep the param names
the same as column names, but it was a matter of "style", not a
necessity. In fact, she also states that "where joined datasets turn
up duplicate column names, it is just as important to make sure you
use distinct parameter names to avoid ambiguous queries".
So it seems a problem... and I'm not enought expert to try to fix it.
Hope you will have the time to do so ;)
