id may be used to identify the transaction in subsequent Read][google.spanner.v1.Spanner.Read], ExecuteSql][google.spanner.v1.Spanner.ExecuteSql], Commit][google.spanner.v1.Spanner.Commit], or Rollback][google.spanner.v1.Spanner.Rollback] calls. Single-use read-only transactions do not have IDs, because single-use transactions do not support multiple requests.
