用于xml构建问题的SQL

Question

我在SQL中的FOR XML子句有问题。数据表中的数据以间隔为间隔（参见下面的示例），在截至目前的数据输出中，我获得了列中每个间隔的相同日期。

SQL表：

ID CTID dDate dtmInterval CO_Forecast AHT_Forecast 
1 2 2015-10-13 08:00:00 5.05004 457.67751 
2 2 2015-10-13 08:15:00 5.24004 457.67751 
3 2 2015-10-13 08:30:00 4.49004 457.67751 
4 2 2015-10-13 08:45:00 4.50004 457.67751 
5 2 2015-10-13 09:00:00 5.65004 457.67751 

我使用此代码在我的FOR XML子句：

SELECT TOP 1000 

[ctID] 
,[forecastData/date/day] = Day(dDate) 
,[forecastData/date/month] = month(dDate) 
,[forecastData/date/year] = year(dDate) 
,[co_forecast] AS [forecastData/dailyData/contactsReceived] 
,[AHT_Forecast] AS [forecastData/dailyData/averageAHT] 

FROM [ProductionForecast].[dbo].[Forecast] 

group by [co_forecast], [AHT_Forecast], [CTID], dDate 

FOR XML PATH ('ctForecast'), ROOT ('forecastImport') 

输出我得到的是以下几点：

<forecastImport> 
    <ctForecast> 
    <ctID>2</ctID> 
    <forecastData> 
     <date> 
     <day>13</day> 
     <month>10</month> 
     <year>2015</year> 
     </date> 
     <dailyData> 
     <contactsReceived>5.05004</contactsReceived> 
     <averageAHT>457.67751</averageAHT> 
     </dailyData> 
    </forecastData> 
    </ctForecast> 
    <ctForecast> 
    <ctID>2</ctID> 
    <forecastData> 
     <date> 
     <day>13</day> 
     <month>10</month> 
     <year>2015</year> 
     </date> 
     <dailyData> 
     <contactsReceived>5.24004</contactsReceived> 
     <averageAHT>457.67751</averageAHT> 
     </dailyData> 
    </forecastData> 
    </ctForecast> 

一切钳开关闭正确的地方，但我连续获得96次相同的日期，哪些服务器谁需要此数据不能读取。

我希望它输出什么是以下几点：

<forecastImport> 
<ctForecast> 
<ctID>95</ctID> 
<forecastData> 
<date><day>01</day><month>11</month><year>2015</year></date> 
<dailyData> 
<contactsReceived>0</contactsReceived> 
<averageAHT>0</averageAHT> 
</dailyData> 
</forecastData> 
</ctForecast> 
<ctForecast> 
<ctID>95</ctID> 
<forecastData> 
<date><day>02</day><month>11</month><year>2015</year></date> 
<dailyData> 
<contactsReceived>594.81653</contactsReceived> 
<averageAHT>387</averageAHT> 
</dailyData> 
</forecastData> 
</ctForecast> 

我已经尝试了很多不同的东西，现在我只看到一个答案，就是让一个存储过程运行起来，这将传输数据到没有dtminterval列的新表，但我想使用我已有的可用，这可能吗？

亲切的问候。

Answer 1

，我发现自己的答案，但要使用此代码：

SELECT 
[CTID] 
,[dDate] 
,[CO_Forecast] = Sum([CO_Forecast]) 
,AHT_Forecast = CASE WHEN Sum([CO_Forecast]) = 0 THEN 0 ELSE SUM(LOAD)/  Sum([CO_Forecast]) 
END 

FROM 
(
SELECT 
[ID] 
,[CTID] 
,[dDate] 
,[dtmInterval] 
,[CO_Forecast] 
,[AHT_Forecast] 
,LOAD = CO_Forecast * AHT_Forecast 

FROM    
[ProductionForecast].[dbo].[Forecast]) AS Sub 

GROUP BY 
[CTID] 
,[dDate]
