Question

[更新]问题：
Leigh提供的查询有效，但出于某种原因，当我替换行和列的名称以将查询从每次点击成本更改为每个注册的成本和每个许可的成本时，我会得到与预期不同的值。

注意：我在下面列出的结果仅适用于每次注册费用，而不是每个许可证的费用。两者都来自同一张桌子，所以如果一个是固定的，很可能第二个会跟风。我还更新了AdReport表以包含Licenses列等。

我的期望

Date    CPR  
1      $31.35   
2      $61.42   
3      $77.85   
4      $78.48   
5      $55.11

我得到了什么

Date    CPR  
1       971.9412  
2       1781.2939  
3       2421.733  
4       2355.4679  
5       1598.164

查询：

 <cfquery name="costPerRegistration" datasource="#dsn#">
SELECT ab.AdMonth AS Date, 
    CASE WHEN SUM(ar.Conversions) > 0 THEN SUM(ab.AdBudget) / SUM(ar.Conversions)
            ELSE 0
            END AS CPR
FROM AdBudget AS ab INNER JOIN AdReport AS ar
      ON  DATEPART(MONTH, ar.ReportDate) = ab.AdMonth
      AND DATEPART(YEAR, ar.ReportDate)  =  ab.AdYear
      AND ar.AdSourceID = ab.AdSourceID
    WHERE ab.AdYear = '2016' 
    AND ar.AdSourceID != 4
    GROUP BY ab.AdMonth
    ORDER BY ab.AdMonth
</cfquery>

<cfquery name="costPerLic" datasource="#dsn#">
SELECT  ab.AdMonth AS Date,

对于表配置感到抱歉，不知道如何使它整洁。此外，我们还有更多的转换（注册）和许可证未在示例数据中显示，只是前10行的数字很少。

如何设置图表以正确绘制图表

我实际上是从问题开始，而不是查询。从一个易于调整的小型硬编码图表开始，以便准确确定应如何构建标签以生成所需的图表。最终分组将确定如何聚合查询数据。

假设您要将2016年1月至5月的“每次点击费用”和“每次注册费用”列为单独的系列。创建一个这样的硬编码示例：

<cfchart> 
    <cfchartseries type="curve" serieslabel="Cost per Clicks">
       <cfchartdata item="1" value="15">
       <cfchartdata item="2" value="50">
       <cfchartdata item="3" value="47">
       <cfchartdata item="4" value="32">
       <cfchartdata item="5" value="65">
    </cfchartseries>
    <cfchartseries type="curve" serieslabel="Cost per Registration">
       <cfchartdata item="1" value="45.52">
       <cfchartdata item="2" value="17.68">
       <cfchartdata item="3" value="28.50">
       <cfchartdata item="4" value="78.62">
       <cfchartdata item="5" value="42.50">
    </cfchartseries>
</cfchart>

制作此图表：

查看cfchartdata标记，表示需要两个查询：一个按月包含“每次点击费用”，另一个按月包含“每次注册费用”。

要计算每次点击费用，请在月份，年份和源ID列上加入AdBudget和AdClick。按月对结果进行分组，并将总预算除以总点击次数：

SQLFiddle Example:

<cfquery name="costPerClick" ....>
SELECT   ab.AdMonth
         , CASE WHEN SUM(ac.AdClicks) > 0 THEN SUM(ab.AdBudget) / SUM(ac.AdClicks)
                ELSE 0
           END AS CostPerClick
FROM    AdBudget ab LEFT JOIN AdClick ac 
          ON  ac.AdMonth = ab.AdMonth 
          AND ac.AdYear = ab.AdYear  
          AND ac.AdSourceID = ab.AdSourceID
WHERE   ab.AdYear = 2016 
AND     ab.AdSourceID <> 4
GROUP BY ab.AdMonth
ORDER BY ab.AdMonth
</cfquery>

然后只需遍历查询即可生成cfchartseries：

<cfchart> 
    <cfchartseries type="curve" serieslabel="Cost per Clicks">
       <cfoutput query="costPerClick">
          <cfchartdata item="#costPerClick.AdMonth#" 
               value="#DecimalFormat(costPerClick.Amount)#">
       </cfoutput>
    </cfchartseries>
</cfchart>

使用上面的提示，您应该能够按照相同的过程生成其他两个查询和系列。

<强>更新

原来我误解了AdReport的结构。由于它包含每月/每年/来源ID组合的多个记录，因此您需要先按月计算总转化次数。然后将结果加入AdBudget。因此，“每次注册成本”查询需要是这样的：

SELECT  ab.AdMonth 
        , CASE WHEN SUM(ar.Conversions) > 0 THEN SUM(ab.AdBudget) / SUM(ar.Conversions)
               ELSE 0
          END AS CPR
FROM    AdBudget ab LEFT JOIN 
        (
            /* Calculate total conversions per month */
            SELECT AdSourceID
                    , DATEPART(MONTH, ReportDate) AS AdMonth
                    , DATEPART(YEAR, ReportDate) AS AdYear
                    , SUM(Conversions) AS Conversions
            FROM   AdReport
            --- first of desired year (2016) to first of next year (exclusive)
            WHERE  ReportDate >= '2016-01-01'
            AND    ReportDate < '2017-01-01'
            AND    AdSourceID <> 4
            GROUP BY AdSourceID
                     , DATEPART(MONTH, ReportDate)
                     ,  DATEPART(YEAR, ReportDate)
        ) 
        ar  ON  ar.AdMonth = ab.AdMonth 
            AND ar.AdYear = ab.AdYear  
            AND ar.AdSourceID = ab.AdSourceID           
GROUP BY ab.AdMonth
ORDER BY ab.AdMonth
