[jira] [Created] (CALCITE-2626) RelBuilder generates wrong field list for join

Pavel Gubin created CALCITE-2626:
------------------------------------

             Summary: RelBuilder generates wrong field list for join
                 Key: CALCITE-2626
                 URL: https://issues.apache.org/jira/browse/CALCITE-2626
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.17.0
            Reporter: Pavel Gubin
            Assignee: Julian Hyde


When building OUTER JOIN RelBuilder doesn't change nullability of underlying fields just copying them as is. But with outer join fields shall become nullable at appropriate sides of join.

The error is at these lines:
https://github.com/apache/calcite/blob/fb7914ec61fc57c8348d9da144e2fbd608c00c61/core/src/main/java/org/apache/calcite/tools/RelBuilder.java#L1546
