-----------------------------------
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.
