  1. showNumMaybe :: (SqlContext c, Num a, IsString b) => Record c (Maybe a) -> Record c (Maybe b)

    relational-schemas Database.Custom.PostgreSQL

    Unsafely show number into string-like type in records.

  2. sumMaybe :: (Num a, AggregatedContext ac, SqlContext ac) => Record Flat (Maybe a) -> Record ac (Maybe a)

    relational-schemas Database.Custom.PostgreSQL

    Aggregation function SUM.

  3. uniqueQueryMaybe' :: UniqueRelation p c r -> QueryUnique (PlaceHolders p, Record c (Maybe r))

    relational-schemas Database.Custom.PostgreSQL

    Join unique sub-query with place-holder parameter p. Query result is Maybe.

  4. class ProjectableFlattenMaybe a b

    relational-schemas Database.Custom.SQLServer

    Interface to compose phantom Maybe nested type.

  5. class ProjectableMaybe (p :: Type -> Type)

    relational-schemas Database.Custom.SQLServer

    Interface to control Maybe of phantom type in records.

  6. avgMaybe :: (Num a, Fractional b, AggregatedContext ac, SqlContext ac) => Record Flat (Maybe a) -> Record ac (Maybe b)

    relational-schemas Database.Custom.SQLServer

    Aggregation function AVG.

  7. caseMaybe :: (OperatorContext c, PersistableWidth b) => Record c a -> [(Record c a, Record c (Maybe b))] -> Record c (Maybe b)

    relational-schemas Database.Custom.SQLServer

    Null default version of case'.

  8. caseSearchMaybe :: (OperatorContext c, PersistableWidth a) => [(Predicate c, Record c (Maybe a))] -> Record c (Maybe a)

    relational-schemas Database.Custom.SQLServer

    Null default version of caseSearch.

  9. flattenMaybe :: ProjectableMaybe p => p (Maybe (Maybe a)) -> p (Maybe a)

    relational-schemas Database.Custom.SQLServer

    Compose nested Maybe phantom type on record.

  10. flattenPiMaybe :: (PersistableWidth a, ProjectableFlattenMaybe (Maybe b) c) => Record cont (Maybe a) -> Pi a b -> Record cont c

    relational-schemas Database.Custom.SQLServer

    Get narrower record with flatten leaf phantom Maybe types along with projection path.
