> _DataStream<User> dataStream =_
> _env.fromElements(_
> _new User("Alice", 4, Instant.ofEpochMilli(1000)),_
> _new User("Bob", 6, Instant.ofEpochMilli(1001)),_
> _new User("Alice", 10, Instant.ofEpochMilli(1002)))_
>
> _.assignTimestampsAndWatermarks(WatermarkStrategy.<User>forBoundedOutOfOrderness(Duration.ofSeconds(60)));_
> _StreamTableEnvironment tableEnv =
> StreamTableEnvironment.create(env);_
> _Table table =_
> _tableEnv.fromDataStream(_
> _dataStream,_
> _Schema.newBuilder()_
> _.column("event_time", "TIMESTAMP(3)")_
> _.column("name", "STRING")_
> _.column("score", "INT")_
> _.watermark("event_time",
> "SOURCE_WATERMARK()")_
> _.build());_
> _table.printSchema();_
> _table.select($("*")).execute().print();_
> and the error I got is :
