如何在部門級別顯示月度參與率並比較每個部門？

我正在開發一個comapny的web應用程序。此應用程序爲用戶提供測驗。現在，我需要爲管理層開發一個功能強大且有意義的儀表板。儀表板必須顯示許多統計信息。他們希望我以這樣的方式設計儀表盤：show％參與度=在部門級別每月進行的測驗次數除以總測驗次數並比較每個部門。如何在部門級別顯示月度參與率並比較每個部門？

的問題是：我有以下的數據庫設計：

Employee表：用戶名，姓名，工作，DivisionID

司表：DivisionID，DivisionName

測驗表：QuizID，標題，說明

UserQuiz Table：UserQuizID，Score，DateTimeComplete，QuizID，用戶名

注意：每個表中的第一個屬性是主鍵。

的SQL查詢我試圖使用顯示過去三個月的結果是：

SELECT COUNT(DISTINCT dbo.UserQuiz.QuizID) AS [Total Number of Quizzes], 
     dbo.Divisions.DivisionName, 
     DATENAME(Month, dbo.UserQuiz.DateTimeComplete) AS Month 
FROM dbo.UserQuiz INNER JOIN 
     dbo.Quiz ON dbo.UserQuiz.QuizID = dbo.Quiz.QuizID 
     INNER JOIN dbo.employee ON dbo.UserQuiz.Username = dbo.employee.Username 
     RIGHT OUTER JOIN dbo.Divisions ON dbo.employee.DivisionCode = dbo.Divisions.SapCode 
GROUP BY dbo.Divisions.DivisionName, 
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete)

另外，我嘗試了許多疑問，每次得到的東西從我想要的東西不同。坦率地說，我不知道如何達到上述要求。

編輯：下面是一些數據的模式：

*「...％的參與=做部級按月通過測驗的總數除以測驗的數量......」 * - 一個費力的員工可能完成所有的測驗，結果爲100％參與了/她的部門。這是否與管理層期望看到的結果相一致？或者我錯過了什麼？ – 2012-01-15 10:13:36

試試這個：

SELECT 
    COUNT(DISTINCT dbo.employee.UserName) UserCount, 
    (SELECT COUNT(*) FROM dbo.Quiz) AS [Total Number of Quizzes], 
    (SELECT COUNT(*) FROM dbo.Quiz)*COUNT(DISTINCT dbo.employee.UserName) AS [Total Number of Quizzes for All users], 
    dbo.Divisions.DivisionName, 
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete) AS MONTH, 
    COUNT(DISTINCT dbo.UserQuiz.QuizId)*COUNT(DISTINCT dbo.employee.UserName) AS [Completed This Month], 
    COUNT(DISTINCT dbo.UserQuiz.QuizId)*100/(SELECT COUNT(*) FROM dbo.Quiz) AS [Percent Completion] 
FROM dbo.employee 
JOIN dbo.Divisions ON dbo.employee.DivisionCode = dbo.Divisions.SapCode 
LEFT JOIN dbo.UserQuiz ON dbo.UserQuiz.Username = dbo.employee.Username 
WHERE dbo.UserQuiz.DateTimeComplete IS NOT NULL 
GROUP BY 
    dbo.Divisions.DivisionName, 
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete)

剛剛完成百分比爲僅在上個月各部門？

SELECT 
    dbo.Divisions.DivisionName, 
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete) AS MONTH, 
    COUNT(DISTINCT dbo.UserQuiz.QuizId)*COUNT(DISTINCT dbo.employee.UserName)*100/((SELECT COUNT(*) FROM dbo.Quiz)*COUNT(DISTINCT dbo.employee.UserName)) AS [Percent Completion] 
FROM dbo.employee 
JOIN dbo.Divisions ON dbo.employee.DivisionCode = dbo.Divisions.SapCode 
LEFT JOIN dbo.UserQuiz ON dbo.UserQuiz.Username = dbo.employee.Username 
WHERE 
    dbo.UserQuiz.DateTimeComplete IS NOT NULL 
AND DATEPART(MONTH, dbo.UserQuiz.DateTimeComplete) = 12 
GROUP BY 
    dbo.Divisions.DivisionName, 
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete)

顯然，COUNT（DISTINCT dbo.UserQuiz）'應該是別的。 – 2012-01-15 09:08:54

@AndriyM好的，更正了。謝謝 – 2012-01-15 09:12:01

謝謝。我非常感謝你的幫助。您的查詢很好，但它給了我奇怪的結果，我不知道爲什麼。請使用一些數據查看數據庫模式的一小部分。 – user1093651 2012-01-15 09:27:02
