我如何使這個統計查詢動態？

我有這樣的用戶表：我如何使這個統計查詢動態？

id(int) | created (datetime)

我展示這不下面的服務器上統計： - 您選擇的日期 - 如果你願意，就每天給你看選擇，每週或每月的統計數據（見查詢）

我已經只是做這樣進行的查詢非常靜：

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

現在我想應該看一下統計，該管理員可以選擇多遠BA他希望能夠顯示統計數據。所以我需要使查詢動態。

原來這裏是靜態查詢我已經做：

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 DAYOFYEAR(DATE_ADD(" + date + ", INTERVAL -5 DAY)) = DAYOFYEAR(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisDaysMinusFiveNumberOfCreatedUsers," + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE DAYOFYEAR(DATE_ADD(" + date + ", INTERVAL -6 DAY)) = DAYOFYEAR(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisDaysMinusSixNumberOfCreatedUsers," + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE DAYOFYEAR(DATE_ADD(" + date + ", INTERVAL -7 DAY)) = DAYOFYEAR(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisDaysMinusSevenNumberOfCreatedUsers," + 
       "  (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," + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE WEEK(DATE_ADD(" + date + ", INTERVAL -1 WEEK)) = WEEK(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisWeeksMinusOneNumberOfCreatedUsers," + 
       "  (SELECT count(statistic_customer_created.id) FROM statistic_customer_created WHERE WEEK(DATE_ADD(" + date + ", INTERVAL -2 WEEK)) = WEEK(statistic_customer_created.created) AND YEAR(" + date + ") = YEAR(statistic_customer_created.created)) as thisWeeksMinusTwoNumberOfCreatedUsers," +

       "";

如：一個解決方案，我可以做（JAVA）：（但是這將創造大量的查詢，我希望有一個更有效辦法做到這一點）（順便說一句，這個例子是不工作的代碼，只是我想到了給你一個什麼樣的解決方案可能是想法）

管理選擇請參閱第20天/周/月

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," + 

}

任何人都有一個建議，我怎麼能更有效地做到這一點？在此先感謝

難道你不能只按一天分組，並在事情的java一側添加單日？ – 2011-12-23 09:48:51

我無法真正看到這將如何幫助我使查詢動態。你是否建議我使用java的for循環，並在查詢中每天分組？ – Ikky 2011-12-23 09:54:51

我會用一系列類似

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

通過採取這些日期，你可以得到1和2之間天前創建的所有的人的區別。

過去7天內創建的人數和上週創建的人數應該相同。

嗯，但因爲我需要從日期 - 1，日期-2等等得到統計...它仍然是一個大型查詢。即使我用java計算日期.... – Ikky 2011-12-23 10:01:56

如果你一次做完所有事情，它就會很大。我會在循環中執行上述查詢，但這可能會變慢。你可以在一個循環中的StringBuilder中建立查詢。 – 2011-12-23 10:28:09

是的，那也是我的想法，我只是想看看是否有其他人有更好的提示，如何在SQL中動態地做到這一點 – Ikky 2011-12-23 10:45:28
