Subject [jira] [Created] (DRILL-3950) CAST(...) * (Interval Constant) gives Internal Exception
Date Mon, 19 Oct 2015 17:29:05 GMT
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,
select cast(empno as Integer) * (INTERVAL '1' DAY)
from emp
results into
java.lang.AssertionError: Internal error: invalid literal: INTERVAL '1' DAY
The reason is that INTERVAL constant is not extracted properly in the cases where this constant
times a CAST() function
