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

             Summary: Wrong result/plan for NOT IN subqueries with disjunction
                 Key: CALCITE-1546
                 URL: https://issues.apache.org/jira/browse/CALCITE-1546
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Vineet Garg
            Assignee: Julian Hyde


Query:
{code}
select * from emp where sal = 4 OR empno NOT IN (select deptno from dept){code}

Plan:
{code}
LogicalProject(EMPNO=[$0], ENAME=[$1], JOB=[$2], MGR=[$3], HIREDATE=[$4], SAL=[$5], COMM=[$6], DEPTNO=[$7], SLACKER=[$8])
  LogicalProject(EMPNO=[$0], ENAME=[$1], JOB=[$2], MGR=[$3], HIREDATE=[$4], SAL=[$5], COMM=[$6], DEPTNO=[$7], SLACKER=[$8])
    LogicalFilter(condition=[OR(=($5, 4), NOT(CASE(IS NOT NULL($10), true, false)))])
      LogicalJoin(condition=[=($0, $9)], joinType=[left])
        LogicalTableScan(table=[[CATALOG, SALES, EMP]])
        LogicalAggregate(group=[{0, 1}])
          LogicalProject(DEPTNO=[$0], i=[true])
            LogicalProject(DEPTNO=[$0])
              LogicalTableScan(table=[[CATALOG, SALES, DEPT]])
{code}

There is no null check branch i.e. with count(\*), count(c) in the plan. This produces wrong results if deptno is null in dept.
