Exact lookup

1. ByMaybeAttr :: WhyNullable

   esqueleto	Database.Esqueleto.Experimental

   No documentation available.

2. FieldAttrMaybe :: FieldAttr

   esqueleto	Database.Esqueleto.Experimental

   The Maybe keyword goes after the type. This indicates that the column is nullable, and the generated Haskell code will have a Maybe type for it. Example:

   User
   name Text Maybe
   

3. class ToMaybe a

   esqueleto	Database.Esqueleto.Experimental

   No documentation available.

4. fromBaseIdMaybe :: ToBaseId ent => SqlExpr (Value (Maybe (Key (BaseEnt ent)))) -> SqlExpr (Value (Maybe (Key ent)))

   esqueleto	Database.Esqueleto.Experimental

   As fromBaseId, but works on Maybe keys.

5. getTableMaybe :: GetFirstTable (SqlExpr (Maybe (Entity t))) ts => ts -> SqlExpr (Maybe (Entity t))

   esqueleto	Database.Esqueleto.Experimental

   A variant of getTable that operates on possibly-null entities.

6. isFieldMaybe :: FieldDef -> Bool

   esqueleto	Database.Esqueleto.Experimental

   Check if the field is `Maybe a`

7. subSelectMaybe :: PersistField a => SqlQuery (SqlExpr (Value (Maybe a))) -> SqlExpr (Value (Maybe a))

   esqueleto	Database.Esqueleto.Experimental

   Execute a subquery SELECT in a SqlExpr. This function is a shorthand for the common joinV . subSelect idiom, where you are calling subSelect on an expression that would be Maybe already. As an example, you would use this function when calling sum_ or max_, which have Maybe in the result type (for a 0 row query).

8. toBaseIdMaybe :: ToBaseId ent => SqlExpr (Value (Maybe (Key ent))) -> SqlExpr (Value (Maybe (Key (BaseEnt ent))))

   esqueleto	Database.Esqueleto.Experimental

   Like toBaseId, but works on Maybe keys.

9. toMaybe :: ToMaybe a => a -> ToMaybeT a

   esqueleto	Database.Esqueleto.Experimental

   No documentation available.

10. getTableMaybe :: GetFirstTable (SqlExpr (Maybe (Entity t))) ts => ts -> SqlExpr (Maybe (Entity t))

    esqueleto	Database.Esqueleto.Experimental.From.Join

    A variant of getTable that operates on possibly-null entities.
