rawSelectStream :: MonadResource m => ([PersistValue] -> Either Text result) -> Text -> [PersistValue] -> ConduitT () result (ReaderT (RawPostgresql SqlBackend) m) () Source #
Run a Text query, with interpolated PersistValues, against a PostgreSQL
backend using cursors, parsing the results with a custom parser function and
streaming them back.
If the parser function returns Left for any row, a PersistException will
be thrown.
