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

             Summary: Extra column in Schema of Recordbatch from scanning Values 
                 Key: DRILL-3019
                 URL: https://issues.apache.org/jira/browse/DRILL-3019
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Other
            Reporter: Sean Hsuan-Yi Chu
            Assignee: Sean Hsuan-Yi Chu


A query which has a pattern:
column IN (1, 1 + 1, 1 + 2)

For the tuple, Calcite makes a plan like
{code}
UnionAll(all=[true])
  UnionAll(all=[true])
    Project(EXPR$0=[+(1, 1)])
      Values
    Project(EXPR$0=[+(1, 2)])
      Values
  Values
{/code}

At execution, the schema of the recordbatch from scanning Values is [`ZERO`(BIGINT: OPTIONAL),
 `*`(BIGINT: OPTIONAL)].

The second column (i.e., `*`) is not supposed to be there.
