Hi, gyula.fora If you’re trying convert Table from a Tuple DataStream, Alias the filed by `as` expression is no supported yet, because all fields are referenced by position in this point. You can simply alias like following syntax: ``` tableEnv.fromDataStream(env.fromElements(Tuple2.of("a", 1)), “name, age"); ``` This should satisfy your purpose. And back to the 1.10 docs, If you are converting Table from a POJO(assuming the POJO person has two fields name and age) DataStream, Alias the filed by `as` is supported because this point all fields are referenced by name, like: ``` tableEnv.fromDataStream(env.fromElements(new Person(“foo", 12)), “age as age_alias, name as user_name,"); ```
