[jira] [Reopened] (DRILL-1938) Select a column named 'user' fails
in Drill
[ https://issues.apache.org/jira/browse/DRILL-1938?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jacques Nadeau reopened DRILL-1938:
-----------------------------------
Assignee: Aman Sinha
I'm reopening as I think the error message is pretty unhelpful. User should receive a parsing message like they do for other situations where they are using a reserved word.
