-------------------------------------

             Summary: Select literal query causes NPE
                 Key: TEIID-2134
                 URL: https://issues.jboss.org/browse/TEIID-2134
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.7, 7.4.1
         Environment: EDS 5.2.0 GA
            Reporter: Hisanobu Okuda
            Assignee: Steven Hawkins


I deployed the attached vdb and run the following query:-

SELECT
  base.category
FROM
  DF.V.BASE AS base
left outer JOIN
  (
    SELECT
      code,
      category
    FROM
      DF.V.TYPES) AS types
ON
  types.code = base.code;

Then, it caused NPE:-
