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"
