[jira] [Created] (SPARK-17034) Ordinal in ORDER BY or GROUP BY should be treated as an unresolved expression

Sean Zhong created SPARK-17034:

             Summary: Ordinal in ORDER BY or GROUP BY should be treated as an unresolved expression
                 Key: SPARK-17034
                 URL: https://issues.apache.org/jira/browse/SPARK-17034
             Project: Spark
          Issue Type: Bug
            Reporter: Sean Zhong


Ordinals in GROUP BY or ORDER BY like "1" in "order by 1" or "group by 1" should be considered as unresolved before analysis. But in current code, it uses "Literal" expression to store the ordinal. This is inappropriate as "Literal" itself is a resolved expression, it gives the user a wrong message that the ordinals has already been resolved.
