> Currently, when we select a field that does not exist, an cannot solve field exception
is thrown. For example,
> {code:java}
> org.apache.flink.table.api.ValidationException: Cannot resolve field [_4]
> {code}
> It would be better to also display the input field list to indicate existing fields,
such as: 
> {code:java}
> org.apache.flink.table.api.ValidationException: Cannot resolve field [_4], input field
list:[_1, _2, _3].
> {code}
