values :: (Default Valuesspec columns columns, Default Unpackspec columns columns) => [columns] -> Query columns Source
Example type specialization:
values :: [(Column a, Column b)] -> Query (Column a, Column b)
Assuming the makeAdaptorAndInstance splice has been run for the
product type Foo:
queryTable :: [Foo (Column a) (Column b) (Column c)] -> Query (Foo (Column a) (Column b) (Column c))
valuesExplicit :: Unpackspec columns columns' -> Valuesspec columns columns' -> [columns] -> Query columns' Source
