> At the moment the following query throws exception:
> {code}
> @Test void testOrderByWithSubQuery() {
>     String sql = "SELECT empno\n"
>         + "FROM emp\n"
>         + "ORDER BY\n"
>         + "CASE WHEN empno IN (1,2) THEN 0 ELSE 1 END";
>     sql(sql).ok();
>   }
> {code}
> {code}
> while converting CASE WHEN `EMP`.`EMPNO` IN (1, 2) THEN 0 ELSE 1 END
> java.lang.RuntimeException: while converting CASE WHEN `EMP`.`EMPNO` IN (1, 2) THEN 0 ELSE 1 END
> 	at org.apache.calcite.sql2rel.ReflectiveConvertletTable.lambda$registerNodeTypeMethod$1(ReflectiveConvertletTable.java:98)
> {code}
> It happens because SqlToRelConverter does not register sub-query inside ORDER BY if query does not have aggregation
