Hi Mich,
I strongly recommend to read a good Scala programming tutorial before
writing on a mailing list.
As the error indicates you are missing generic parameters. If you don't
know the parameter use `Array[TypeInformation[_]]` or `TableSink[_]`.
For the types class you need to import the types class
"org.apache.flink.table.api.Types".
Regards,
Timo

This is the code in Scala
val tableEnv = TableEnvironment.getTableEnvironment(streamExecEnv)
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 fieldNames: Array[String] = Array("key", "ticker",
"timeissued", "price")
val fieldTypes: Array[TypeInformation] = Array(Types.STRING,
Types.STRING, Types.STRING, Types.Float)
val sink: TableSink = new CsvTableSink(writeDirectory+fileName,
fieldDelim = ",")
tableEnv.registerTableSink("CsvSinkTable", fieldNames, fieldTypes,
sink)
result.insertInto("CsvSinkTable")
When compiling I get the following error

May be I am not importing the correct dependencies.
