Hi @twalthr I have test this case using the first approach of FLINK-6896.
without `as` clause. It's works well. And with the `as` clause, It can be fixed
by add a case match in
`StreamTableEnvironment#validateAndExtractTimeAttributes`. the code as follows:
`case (Alias(child, name,_), _) => fieldNames = name :: fieldNames` What do
you think?
