> 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}
