A good practice should be to use "boolean" for not nullables (the primitive
one)
as it can't be null; reserve the wrapper Boolean for values which can be null.
This has nothing to do with SQL of course ;-)
All right lets check the case of IsUserInRole.isUserInRole does it
really make sense to answer to the question:
"Is user XXXX in role YYYYY?" with a null? if we are not sure, shoulnt
we default to "false" (or throw an exception?)
