> Example:
> {code:java}
> @Test void testAggregateSort() {
> final String query = "select max(\"product_class_id\") "
> + "from (select * from \"product\" order by \"brand_name\" limit 10) t";
> final String expected = "SELECT MAX(\"product_class_id\")\n"
> + "FROM \"foodmart\".\"product\"\n"
> + "ORDER BY \"brand_name\"\n"
> + "FETCH NEXT 10 ROWS ONLY";
> sql(query).ok(expected);
> } {code}
> In the above example, the order of aggregation and sorting is reversed, and
> such a query will return an error in some query sources
