Kunal Khatua commented on DRILL-3950:
-------------------------------------
[~priteshm] looks like this relates to calcite. We can verify this as part of
Calcite upgrade.
> CAST(...) * (Interval Constant) gives Internal Exception

> Key: DRILL-3950
> URL: https://issues.apache.org/jira/browse/DRILL-3950
> Project: Apache Drill
> Issue Type: Bug
> Components: Query Planning & Optimization
> Reporter: Sean Hsuan-Yi Chu
> Assignee: Jinfeng Ni
> Labels: interval
>
> For example,
> {code}
> select cast(empno as Integer) * (INTERVAL '1' DAY)
> from emp
> {code}
> results into
> {code}
> java.lang.AssertionError: Internal error: invalid literal: INTERVAL '1' DAY
> {code}
> The reason is that INTERVAL constant is not extracted properly in the cases
> where this constant times a CAST() function
