      Description

      when i run those code as below, i got some error messages.

      //MaterializationTest
      @Test public void testJoinToJoin0() {
          String mv = ""
              + "select \"deptno\" from\n"
              + "\"emps\" intersect select \"deptno\"  from \"depts\"";
          String query = ""
              + "select \"deptno\" from\n"
              + "\"depts\" intersect select \"deptno\" from \"emps\"";
          checkMaterialize(mv, query, true);
        }
      

      java.lang.AssertionError:
      Expected: a string containing "EnumerableTableScan(table=[[hr, m0]])"
      but: was "PLAN=EnumerableCalc(expr#0..1=[

      {inputs}

      ], expr#2=[2:BIGINT], expr#3=[=($t1, $t2)], deptno=[$t0], $condition=[$t3])\n EnumerableAggregate(group=[

      {0}], agg#0=[COUNT()])\n EnumerableUnion(all=[true])\n EnumerableAggregate(group=[{0}

      ], agg#0=[COUNT()])\n EnumerableTableScan(table=[[hr, depts]])\n EnumerableAggregate(group=[

      {1}

      ], agg#0=[COUNT()])\n EnumerableTableScan(table=[[hr, emps]])\n\n"
