Question

我正在为comapny开发一个Web应用程序。此应用程序为用户提供测验。现在，我需要为管理层开发一个功能强大且有意义的仪表板。仪表板必须显示许多统计信息。他们希望我以这样的方式设计此仪表板：show％participation =完成的测验数除以部门级月度测验的总数，并比较每个部门。

问题是：我有以下数据库设计：

员工表：用户名，姓名，职位，分部ID

分部表：DivisionID，DivisionName

测验表：QuizID，标题，描述

UserQuiz表：UserQuizID，得分，DateTimeComplete，QuizID，用户名

注意：每个表中的第一个属性是主键。

我试图用来显示过去三个月结果的SQL查询是：

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)

此外，我尝试了很多查询，每次都有不同于我想要的东西。坦率地说，我对如何达到上述要求一无所知。

编辑：这是包含一些数据的模式：

试试这个：

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)

只是上个月每个部门的完成百分比？

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)

如何在部门级别每月显示％参与率并比较每个部门？
