DistinctOnOrderBy (Maybe (NonEmpty PrimExpr)) [OrderExpr] (PrimQuery' a)

Represents both DISTINCT ON and ORDER BY clauses. In order to represent valid SQL only, DISTINCT ON expressions are always interpreted as the first ORDER BYs when present, preceding any in the provided list. See distinctOnOrderBy.
