MySQL views and MS Access

So the CASE... WHEN solution posted previously works very well for MySQL. Lots of nice views popping up and databases going forward.

However, when attempting to link a view as a table in Microsoft Access the calculated columns won't show. It's a real drag as it is such quick work to use views to de-normalize data for backwards compatibility.

Enter the pass-through query which solves this problem as long as having the data in an Access query is suitable.
