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

["Matthias Rosenthaler (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DRILL-7893?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matthias Rosenthaler updated DRILL-7893:
----------------------------------------
    Description: 
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]

  was:
