Description
This module defines core query type.
- type QueryCore = Restrictings Flat (QueryJoin ConfigureQuery)
- extractCore :: QueryCore a -> ConfigureQuery (((a, QueryRestriction Flat), JoinProduct), Duplication)
- type OrderedQuery c m p r = Orderings c m (PlaceHolders p, Projection c r)
Core query monad
type QueryCore = Restrictings Flat (QueryJoin ConfigureQuery) Source #
Core query monad type used from flat(not-aggregated) query and aggregated query.
extractCore :: QueryCore a -> ConfigureQuery (((a, QueryRestriction Flat), JoinProduct), Duplication) Source #
Extract QueryCore computation.
type OrderedQuery c m p r = Orderings c m (PlaceHolders p, Projection c r) Source #
OrderedQuery monad type with placeholder type p. Projection must be the same as Orderings context type parameter c.
