この統計クエリを動的にするにはどうすればよいですか？

Question

私は、このユーザーテーブルを持っている：

id(int) | created (datetime) 

私は、次のないサーバの統計を表示しています： - あなたは日付 を選択 - あなたが毎日表示したい場合は、（参照、毎週または毎月の統計を選択クエリ）

私はちょうどこのようにそれをすることによって、クエリは非常に静的行った：

WEEK(DATE_ADD(" + date + ", INTERVAL -2 WEEK) // Shows how many users that has been created from two weeks before current date to current date 

は、今私は統計を見てみなければならない管理者がどこまでBAを選択することができるようにしたいです彼は統計を表示したいと考えています。 私はクエリを動的にする必要があります。

String sQuery = "SELECT " + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created) as totalNumberOfCreatedUsers, " + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE DAYOFYEAR(" + date + ") = DAYOFYEAR(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisDaysNumberOfCreatedUsers, " + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE DAYOFYEAR(DATE_ADD(" + date + ", INTERVAL -1 DAY)) = DAYOFYEAR(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisDaysMinusOneNumberOfCreatedUsers," + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE DAYOFYEAR(DATE_ADD(" + date + ", INTERVAL -2 DAY)) = DAYOFYEAR(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisDaysMinusTwoNumberOfCreatedUsers," + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE DAYOFYEAR(DATE_ADD(" + date + ", INTERVAL -3 DAY)) = DAYOFYEAR(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisDaysMinusThreeNumberOfCreatedUsers," + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE DAYOFYEAR(DATE_ADD(" + date + ", INTERVAL -4 DAY)) = DAYOFYEAR(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisDaysMinusFourNumberOfCreatedUsers," +

       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE WEEK(" + date + ") = WEEK(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisWeeksNumberOfCreatedUsers," +

       ""; 

は、例えば：私は行うことができ 一つの解決方法（Javaの）：ここで

は私が作ったオリジナルの静的なクエリである（しかし、これは大規模なクエリを作成し、そして私は、より効率的にしたいですそれを行う方法）（ところで、この例では、私はあなたと解決策は何ができるかのアイデアを与えることを考えるだけで何か）

を、コードを動作していない管理者は、20日/週/月を参照することを選択しました

String addToQuery = ""; 
int daysWeeksMonthsToLookBack = inputFromUser // inputFromUser = 20 in this example 
for(int i=0; i<daysWeeksMonthsToLookBack; i++){ 
    addToQuery += "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE DAYOFYEAR(DATE_ADD(" + date + ", INTERVAL -" + i + " DAY)) = DAYOFYEAR(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisDaysMinusFiveNumberOfCreatedUsers," + 

} 

どのように私はこれをより効率的に行うことができますか？ おかげで、事前

Answer 1

に私はあなたが1および2日前の間に作成されたすべてのそれらを得ることができますこれらの日付の差をとることにより

SELECT count(s.id) 
FROM statistic_customer_created s 
WHERE s.created >= {date calculated in Java} 

などの範囲を使用しているだろう。

過去7日間に作成されたものと先週作成されたものの数は同じでなければなりません。
