範囲でMySQLのクエリの場合に、通貨

Question

の場合、私はかなりの列は次のようになり、テーブル「注文」があります。

| order_id | shop_id | order_total | currency | created_at | 

今私は、クエリを作りたい、のように見えるテーブルを返します。この：間隔は、日付の間隔で

| interval | currency | sum | 

、通貨は通貨と合計がその通貨の間隔ですべての注文の合計で、です。 SAの例は次のようになります。

| 2012-08-12-2012-09-12 | EUR | 540922 | 

| 2012-08-12-2012-09-12 | DKK | 43215 | 

| 2012-09-12-2012-10-12 | EUR | 123643 | 

| 2012-09-12-2012-10-12 | DKK | 0  | 

私はすでに通貨をdiregardsクエリを持っていますが、私は任意のアイデア...それは考慮に通貨を取るようにする方法を知りませんか？

Heresは私が今使っているクエリの例です。もちろん、実際のクエリはコードによって生成されますが、これは単なる例です。

SELECT CASE 
     WHEN created_at BETWEEN '2012-08-12' AND '2012-09-12' THEN '2012-08-12-2012-09-12' 
     WHEN created_at BETWEEN '2012-09-12' AND '2012-10-12' THEN '2012-09-12-2012-10-12' 
     WHEN created_at BETWEEN '2012-10-12' AND '2012-10-14' THEN '2012-10-12-2012-10-14' 
     end AS intrvl, 
     Sum(order_total) 
FROM `order` o 
WHERE shop_id = 4 
     AND created_at BETWEEN '2012-08-12' AND '2012-11-17' 
GROUP BY CASE 
      WHEN created_at BETWEEN '2012-08-12' AND '2012-09-12' THEN '2012-08-12-2012-09-12' 
      WHEN created_at BETWEEN '2012-09-12' AND '2012-10-12' THEN '2012-09-12-2012-10-12' 
      WHEN created_at BETWEEN '2012-10-12' AND '2012-10-14' THEN '2012-10-12-2012-10-14' 
      end
