xzh_dz updated CALCITE-3626:
----------------------------
    Description: 
when i run those codes as below, i get some error messages.it seems like 
materialized view can not be matched correctly.

code:

{code:java}
@Test public void testSort0() {
    String mv = "select \"deptno\", \"commission\" from \"emps\" order by 
\"deptno\"";
    String query = "select \"deptno\" , \"commission\" from \"emps\" order by 
\"commission\"";
    checkMaterialize(mv, query, true);
  }
{code}

{code:java}
@Test public void testSort1() {
    String mv = "select \"deptno\", \"commission\" from \"emps\" order by 
\"deptno\"";
    String query = "select \"commission\", \"deptno\"  from \"emps\" order by 
\"commission\"";
    checkMaterialize(mv, query, true);
  }
{code}

exception:
java.lang.AssertionError: 
Expected: a string containing "EnumerableTableScan(table=[[hr, m0]])"
     but: was "PLAN=EnumerableSort(sort0=[$0], dir0=[ASC])\n  
EnumerableCalc(expr#0..4=[{inputs}], commission=[$t4], deptno=[$t1])\n    
EnumerableTableScan(table=[[hr, emps]])\n\n"
