Passing the individual table coilumn values to the local variables


Hi,

The following works fine

   tableEnv.registerDataStream("priceTable", splitStream, 'key, 'ticker, 'timeissued, 'price)
    val result = tableEnv.scan("priceTable").filter('ticker === "VOD" && 'price > 99.0).select('key, 'ticker, 'timeissued, 'price)
    val r = result.toDataStream[Row]
    r.print()

Now I would like to get the individual column values from priceTable into local variables

This does not seem to work

val key = tableEnv.scan("priceTable").select('key).toDataStream[Row]
val ticker = tableEnv.scan("priceTable").select('ticker).toDataStream[Row]
 val timeissued = tableEnv.scan("priceTable").select('timeissued).toDataStream[Row]
 val price = tableEnv.scan("priceTable").select('price).toDataStream[Row]

What alternatives are there?

Thanks

Dr Mich Talebzadeh
