Incorrect column name in Selection shows empty result

When specifying the wrong column name in Selection, result shows empty instead of error message.
It would be a better user experience to show error message: "Can't find Column X" to help debugging.

Start by locating the Selection handling for queries with an invalid column name and reproduce the empty-result behavior described in the issue. Trace the existing error-reporting path, then verify that selecting Column X produces the requested "Can't find Column X" message instead of an empty result.
