[jira] [Created] (CALCITE-7043) Type inferred for SqlItemOperator has incorrect nullability

Mihai Budiu created CALCITE-7043:
------------------------------------

             Summary: Type inferred for SqlItemOperator has incorrect nullability
                 Key: CALCITE-7043
                 URL: https://issues.apache.org/jira/browse/CALCITE-7043
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.39.0
            Reporter: Mihai Budiu
            Assignee: Mihai Budiu


This issue is related to CALCITE-6764

Accessing a field within a nullable ROW should always produce a nullable result, even if the field itself is not nullable. The previous issue fixed this bug in the Validator, but the same problem persists in SqlItemOperator.inferReturnType.
