Project: Calcite
Issue Type: Bug
Components: core
Reporter: Xurenhe

SubstitutionVisitor don't support pull up filter under query's aggregate, for
example:
{code:java}
// test case
@Test void testNoEqualFilterInAgg() {
final String mv = ""
+ "select \"name\", \"deptno\", count(distinct \"commission\") as cnt\n"
+ "from \"emps\"\n"
+ " group by \"name\", \"deptno\"";
final String query = ""
+ "select \"deptno\", count(distinct \"commission\") as cnt\n"
+ "from \"emps\" where \"name\" <> 'jack'\n"
+ "group by \"deptno\"";
sql(mv, query).ok();
}{code}
{code:java}
// exec mv match fail
+Materialized view failed to be matched by optimized
results:+java.lang.AssertionError: Materialized view failed to be matched by
