このようなテーブルが1つあります...

+---------+------------+------+-------+
|  City   | NamePeople | Age  | Money |
+---------+------------+------+-------+
| Paris   | John       |  10  |  200  |
| London  |  Marie     |  21  |  300  |
| Paris   |  Kevin     |  50  |  250  |
| Paris   |  Julia     |  45  |  150  |
+---------+------------+------+-------+

このような範囲の結果が必要です

+---------------+------------+-----------------------+-------------------------+
|      City     | Sum(Money) | CountPeopleWithAge<30 | CountPeopleWithAge>30   |
+---------------+------------+-----------------------+-------------------------+
|   Paris       |       600  |                    1  |                      2  |
|   London      |       300  |                    1  |                      0  |
+---------------+------------+-----------------------+-------------------------+

これを sql select で行うにはどうすればよいですか?

ありがとう。

このクエリを使用できます。

SELECT City, 
    SUM(Money), 
   SUM(case when Age < 30 then 1 else 0 end),
   SUM(case when Age > 30 then 1 else 0 end)
FROM tableA
GROUP BY City
