Computed Columns In Stream to Table Conversion

[Aeden Jameson]

Hi

   How does one specify computed columns when converting a DataStream
to a temporary view? For example

        final DataStream<Message> stream = env.addSource(..);

        tEnv.createTemporaryView(
                "myTable"
                stream
                ,$("col1")
                ,$("col2")
                ....
                ,$("Do computed columns work here?")
        );

More specifically the compute expression i'd like to use involves
'case when.... then 1 else 0 end'
