Description
Currently filter is parsed verbatim to a WHERE clause in the layer query. This can force some rather awkward syntax like FILTER revenue = (SELECT max(revenue) FROM sales) rather than FILTER revenue = max(revenue)
We should think about how this syntax can be improved

Start by examining how FILTER is parsed and passed into the layer query's WHERE clause, using the two syntax examples in the issue as the initial cases. Done means the proposed FILTER syntax is defined clearly and produces the intended query without requiring the awkward subquery form.
