             Summary: Remove column suggestion when the candidate list is empty for unresolved column/attribute/map key
                 Key: SPARK-40185
                 URL: https://issues.apache.org/jira/browse/SPARK-40185
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.4.0
            Reporter: Vitalii Li


For unresolved column, attribute or map key an error message might contain suggestions from the list. However, when the list is empty the error message looks incomplete:

`[UNRESOLVED_COLUMN] A column or function parameter with name 'YrMo' cannot be resolved. Did you mean one of the following? []`

This issue is to make final suggestion to show only if suggestion list is non empty.
