             Summary: Materialized recognition failed when query contains cast 
type conversion
                 Key: CALCITE-4194
                 URL: https://issues.apache.org/jira/browse/CALCITE-4194
             Project: Calcite
          Issue Type: Wish
            Reporter: xzh_dz


There is a semantic equivalent case, which should be able to materialize and 
identify successfully, but failed. This case can be reproduced as below.
{code:java}
// MaterializedViewSubstitutionVisitorTest
@Test void testCastMvMatch() {
  sql(
      "select \"empid\", count(\"deptno\") from \"emps\" where \"empid\" > 10 
group by \"empid\"",
      "select \"empid\", count(cast(\"deptno\" as bigint)) from \"emps\" where 
\"empid\" > 10 group by \"empid\"")
      .ok();
}
{code}
Here is the error message:
