--------------------------------------

             Summary: Using the column 'user' in Table API is not possible
                 Key: FLINK-22999
                 URL: https://issues.apache.org/jira/browse/FLINK-22999
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / API
            Reporter: Martijn Visser


Using the following code:

{code:java}
        final StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env);

        final DataStream<Row> clickStream =
                env.fromElements(
                        Row.of("Bob", "ORDER_ENTERED", "1623758400"),
                        Row.of("Alice", "ORDER_ENTERED", "1623758700"),
                        Row.of("Bob", "ADDRESS_ENTERED", "1623759000"));

        final Table clickTable = tableEnv.fromDataStream(clickStream).as("user","pageType", "ts");

        tableEnv.createTemporaryView("ClickStream", clickTable);

        tableEnv.executeSql("CREATE VIEW FirstPageVisits AS SELECT user, pageType, ts FROM ClickStream WHERE pageType = 'ORDER_ENTERED'");

clickTable.execute().print();
{code}

Throws the following stacktrace:
