[jira] [Created] (DRILL-7893) Column alias is not working for a parquet file

Matthias Rosenthaler created DRILL-7893:
-------------------------------------------

             Summary: Column alias is not working for a parquet file
                 Key: DRILL-7893
                 URL: https://issues.apache.org/jira/browse/DRILL-7893
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Parquet
    Affects Versions: 1.17.0
            Reporter: Matthias Rosenthaler
         Attachments: values.parquet

The following query results in a column name of "shot_id" instead of the expected "x".

SELECT shot_id as x FROM values.parquet WHERE step = 'RPCurve_001'

The strange thing is, if I modify the query, like adding a limit clause, it is working:

SELECT shot_id as x FROM values.parquet WHERE step = 'RPCurve_001' LIMIT 1000[^values.parquet]
