[jira] [Created] (CALCITE-766) RexBuilder.ensureType() does not correctly handle the case when nullability needs to be ignored

Mehant Baid created CALCITE-766:
-----------------------------------

             Summary: RexBuilder.ensureType() does not correctly handle the case when nullability needs to be ignored
                 Key: CALCITE-766
                 URL: https://issues.apache.org/jira/browse/CALCITE-766
             Project: Calcite
          Issue Type: Bug
            Reporter: Mehant Baid
            Assignee: Julian Hyde


In ensureType() we don't correctly handle the case when nullability should be ignored. We still compare digests of the two types which returns false even when the types are the same but differ only in nullability. 

Created a [Pull Request|https://github.com/apache/incubator-calcite/pull/97] with the description of the issue and a unit test.
