-from p of persons
-leftjoin c of cities
-on p.city.name == c.name
-select p.name, c.name
+from p in persons
+leftjoin c in cities on p.city.name == c.name
+where c.name == 'Shanghai'
+select p.name, c.name as cityName
-from p of persons
+from p in persons
 groupby p.gender
 having p.gender == 'Male'
 select p.gender, max(p.age)
-from p of persons
-orderby p.age desc
-thenby p.name asc
+from p in persons
+orderby p.age in desc, p.name
 select p.name
