1. binaryspecMaybeFields :: WithNulls Binaryspec a b -> Binaryspec (MaybeFields a) (MaybeFields b)

   opaleye	Opaleye.Internal.MaybeFields

   No documentation available.

2. catMaybeFields :: SelectArr i (MaybeFields a) -> SelectArr i a

   opaleye	Opaleye.Internal.MaybeFields

   The Opaleye analogue of catMaybes. Most commonly you will want to use this at type

   catMaybeFields :: Select (MaybeFields a) -> Select a
   

3. eqPPMaybeFields :: EqPP a b -> EqPP (MaybeFields a) (MaybeFields b)

   opaleye	Opaleye.Internal.MaybeFields

   No documentation available.

4. fromFieldsMaybeFields :: FromFields fields haskells -> FromFields (MaybeFields fields) (Maybe haskells)

   opaleye	Opaleye.Internal.MaybeFields

   No documentation available.

5. fromMaybeFields :: Default IfPP b b => b -> MaybeFields b -> b

   opaleye	Opaleye.Internal.MaybeFields

   The Opaleye analogue of fromMaybe

6. fromMaybeFieldsExplicit :: IfPP b b -> b -> MaybeFields b -> b

   opaleye	Opaleye.Internal.MaybeFields

   No documentation available.

7. ifPPMaybeFields :: IfPP a b -> IfPP (MaybeFields a) (MaybeFields b)

   opaleye	Opaleye.Internal.MaybeFields

   No documentation available.

8. mapMaybeFieldsWithNulls :: ProductProfunctor p => p (Field SqlBool) (Field SqlBool) -> WithNulls p a b -> WithNulls p (MaybeFields a) (MaybeFields b)

   opaleye	Opaleye.Internal.MaybeFields

   This is only safe if b is OK with having nulls passed through it when they claim to be non-null.

9. matchMaybe :: Default IfPP b b => MaybeFields a -> (Maybe a -> b) -> b

   opaleye	Opaleye.Internal.MaybeFields

   Use a Haskell \case expression to pattern match on a MaybeFields.

   example :: MaybeFields (Field SqlInt4) -> Field SqlInt4
   example mf = matchMaybe mf $ \case
   Nothing -> 0
   Just x  -> x * 100
   

10. nullableToMaybeFields :: FieldNullable a -> MaybeFields (Field a)

    opaleye	Opaleye.Internal.MaybeFields

    Convert NULL to nothingFields and non-NULL to a justFields
