變量值

Question

[增訂]問：
那利提供工作，但查詢出於某些原因，當我更換了行和列的名稱來查詢，從每點擊成本每登記成本變更和每個許可證的成本，我會得到不同於預期的值。

注意： 下面列出的結果僅用於每個註冊的成本，而不是每個許可的成本。都來自同一張桌子，所以如果一個人是固定的，最有可能的第二個會跟風。我也更新了AdReport表包括許可證柱等

我預計

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

我有什麼

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

查詢：

<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, 
    CASE WHEN SUM(al.Licenses) > 0 THEN CAST(SUM(ab.AdBudget)/SUM(al.Licenses) AS smallmoney) 
      ELSE 0 
      END AS CPL 
FROM AdBudget AS ab INNER JOIN AdReport AS al 
     ON DATEPART(MONTH,al.ReportDate) = ab.AdMonth 
     AND DATEPART(YEAR,al.ReportDate) = ab.AdYear 
     AND al.AdSourceID = ab.AdSourceID 
WHERE ab.AdYear = 2016 
AND  ab.AdSourceID != 4 
GROUP BY ab.AdMonth 
ORDER BY ab.AdMonth 
</cfquery> 

代碼：

<cfloop index = "i" from = "1" to = "#AdBudget.RecordCount#"> 
    <cfset Clicks.Click[i] = AdBudget.Budgeting/Clicks.Click[i]> 
    <cfset Registrations.Conver[i] = AdBudget.Budgeting/Registrations.Conver[i]> 
    <cfset Licenses.License[i] = AdBudget.Budgeting/Licenses.License[i]> 
</cfloop>

對不起關於表配置，不知道如何使它整潔。此外，我們還有更多的轉換（註冊）和許可證，這些數據在示例數據中沒有顯示，只是發生在前10行的數字較少。

如何設置圖表以確保其正常

圖表他們，我會實際上這個問題開始，而不是查詢。從一個小的硬編碼圖表開始，這個圖表很容易調整，以便準確找出應該如何構建標籤以生成所需的圖表。最終的分組將決定你應該如何聚合查詢數據。

假設您想要將2016年1月至5月的「每次點擊費用」和「每次註冊費用」列爲單獨系列。創建一個硬編碼的例子是這樣的：

<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> 

產生以下圖表：

望着cfchartdata標籤，表示需要兩個疑問：一個包含了「每次點擊費用」按月，以及另一個月的「每註冊成本」。

計算每次點擊的成本，上月加入AdBudget和AdClick，一年和源ID列。集團的結果通過一個月，由總點擊劃分總預算：

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> 

然後簡單地通過查詢循環來生成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，您應該能夠按照相同的流程生成其他兩個查詢和系列。

更新：

原來我誤會AdReport的結構。由於它包含每個月/年/源ID組合的多個記錄，因此您需要先計算每月的總轉化次數。然後將結果加入AdBudget。因此，「每個註冊成本」查詢需要如下所示：

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
