-----------------------------------
Hi Jark, I am dealing with the RowData objects in RichSinkFunction and need to
extract values from them, but I can not extract the values correctly as they
were not string type. Maybe you can view the codes below
{code:java}
@Override
public void invoke(RowData value, Context context) {
String v = value.getString(0).toString;
}{code}
> getString value from any datatype columns

> Hope flink would support getting string value from any other datatype column,
> such as from int、decimal column. At current flink would throw cast exception
> when we do that.
