> The {{RelBuilder#field}} method that creates a {{RexNode}} based on alias + fieldName throws an {{IllegalArgumentException}} if the corresponding field is not found:
> {code}
> public RexNode field(int inputCount, String alias, String fieldName) {
> ...
> throw new IllegalArgumentException("no aliased field found; fields are: " + fields);
> }
> {code}
> However, the exception message does not include the requested {{alias}} & {{fieldName}}, which is relevant information, definitively useful for troubleshooting.
