>                 Key: DRILL-2661
>                 URL: https://issues.apache.org/jira/browse/DRILL-2661
>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Client - JDBC
>    Affects Versions: 0.8.0
>            Reporter: Daniel Barclay (Drill)
>
> References to columns that do not exist in INFORMATION_SCHEMA tables/views yield errors, which is inconsistent with the behavior elsewhere, in which references to columns that do not exist simply yield null.
> Is this intentional (e.g., because for INFORMATION_SCHEMA tables we know what columns we provide (i.e., they're not user data files which might have different columns at different points in time))?
