> The rewrite of a set predicate is being bypassed when all of the in values are constants, but when pushed through a view with a convert on the left expression there is still optimizations that can be performed.
> For example:
> select * from (select e1, e2 from pm1.g1 union all select convert(e2, string), e2 from pm1.g2) x where e1 in ('1', '2')
> such that e1 is string and e2 is integer, we expect that the second branch will have criteria of the form "e2 in (1, 2)" - with no conversion.
