[jira] [Created] (DRILL-3950) CAST(...) * (Interval Constant) gives Internal Exception

Sean Hsuan-Yi Chu created DRILL-3950:
----------------------------------------

             Summary: 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: Sean Hsuan-Yi Chu


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
