可以通过动态旋转表在SSRS中制作Tablix报告吗？

Question

我的查询结果是pivoted表，显示从当前月份开始的12个月和总金额。几个月是动态的，所以在十月份，表中的第一列将是十一月，最后一列将是十月（当前一列）。

我如何可以创建简单的表矩阵或使用该结果矩阵集？我主要关心的是如何在Tablix中创建动态的月份名称？

这可能吗？

UPDATE：

我重命名的列值从1到12，但是，当我尝试写来回十月像一个表达式：=Month(Today()) - CInt(Fields!ID10.Value)它只是给了我一个当前月份数。 我错过了什么？

UPDATE： 数据表日历的结构是这样的：

所以我修改查询：

DECLARE @CurrentMonth DATE = DATEADD(MONTH, DATEDIFF(MONTH, '19000101', GETDATE()), '19000101'); 
--print @CurrentMonth 

SELECT 
    M_00 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 0 THEN 1 END), 
    M_01 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 1 THEN 1 END), 
    M_02 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 2 THEN 1 END), 
    M_03 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 3 THEN 1 END), 
    M_04 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 4 THEN 1 END), 
    M_05 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 5 THEN 1 END), 
    M_06 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 6 THEN 1 END), 
    M_07 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 7 THEN 1 END), 
    M_08 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 8 THEN 1 END), 
    M_09 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 9 THEN 1 END), 
    M_10 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 10 THEN 1 END), 
    M_11 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 11 THEN 1 END) 
FROM 
    dbo.tblCalendar c 
     /* changed "YearNum, MonthNum" instead of "(YEAR(c.dt), MONTH(c.dt)" */ 
    CROSS APPLY (VALUES (DATEFROMPARTS(YearNum, MonthNum, 1))) fom (FirstOfMonth) 
WHERE 
    /* changed c.MonthNum instead of c.dt */ 
    c.MonthNum >= MONTH(DATEADD(MONTH, -11, @CurrentMonth)) 
    /* changed c.MonthNum instead of c.dt */ 
    AND c.MonthNum < MONTH(DATEADD(MONTH, 1, @CurrentMonth)); 

是正确的吗？

对不起，我在这里感到困惑。这个想法不是使用动态sql吗？ 只是用我的查询，这就是：

;WITH cte_TopClasses 
AS ( 
SELECT 
     c.YearNum, 
     c.MonthNum, 
     DD.ClassCode, 
     ISNULL(SUM(prm.Premium),0) as NetWrittenPremium 
FROM tblCalendar c 
LEFT JOIN ProductionReportMetrics prm ON c.YearNum = YEAR(prm.EffectiveDate) and c.MonthNum = MONTH(prm.EffectiveDate) 
      AND CompanyGUID = '18E04C99-D796-4CFA-B1E7-28328321C8AD'  
LEFT JOIN [dbo].[Dynamic_Data_GLUnitedSpecialty] DD on prm.QuoteGUID = DD.QuoteGuid 
WHERE (c.YearNum = YEAR(GETDATE())-1 and c.MonthNum >= MONTH(GETDATE())+1) OR 
     (c.YearNum = YEAR(GETDATE()) and c.MonthNum <= MONTH(GETDATE())) 
GROUP BY c.YearNum, 
      c.MonthNum, 
      DD.ClassCode   
    ) 

select * from cte_TopClasses 

OUTPUT：

Answer 1

相信在数据源表名必须和模式被保存为静态。据说，你可以根据当前月份的函数来命名SSRS中的列。因此，您可以让数据集始终将列返回为11到0，并使SSRS动态地将Tablix列命名为当前月份减列名称。

Answer 2

SSRS需要一组固定的输入列，这使得动态交换查询完全不兼容。将数据带入未知的SSRS，并让SSRS在矩阵上进行转换。

编辑...使用非动态SQL ...

做沿着这些路线的东西...

DECLARE @CurrentMonth DATE = DATEADD(MONTH, DATEDIFF(MONTH, '19000101', GETDATE()), '19000101'); 

SELECT 
    M_00 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 0 THEN 1 END), 
    M_01 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 1 THEN 1 END), 
    M_02 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 2 THEN 1 END), 
    M_03 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 3 THEN 1 END), 
    M_04 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 4 THEN 1 END), 
    M_05 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 5 THEN 1 END), 
    M_06 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 6 THEN 1 END), 
    M_07 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 7 THEN 1 END), 
    M_08 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 8 THEN 1 END), 
    M_09 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 9 THEN 1 END), 
    M_10 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 10 THEN 1 END), 
    M_11 = COUNT(CASE WHEN DATEDIFF(MONTH, fom.FirstOfMonth, @CurrentMonth) = 11 THEN 1 END) 
FROM 
    dbo.Calendar c 
    CROSS APPLY (VALUES (DATEFROMPARTS(YEAR(c.dt), MONTH(c.dt), 1))) fom (FirstOfMonth) 
WHERE 
    c.dt >= DATEADD(MONTH, -11, @CurrentMonth) 
    AND c.dt < DATEADD(MONTH, 1, @CurrentMonth); 

查询输出...

M_00  M_01  M_02  M_03  M_04  M_05  M_06  M_07  M_08  M_09  M_10  M_11 
----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- 
30   31   31   30   31   30   31   28   31   31   30   31 

的想法是列中的数据随着月份的进展而循环列，但列名始终保持不变......因此，它始终与SSRS一起玩得很好。

然后，回到SSRS中，而不是显示查询中的标题，使用公式表达式。就像

=MonthName(month(Now())) 
=MonthName(month(Now()) + 1) 
=MonthName(month(Now()) + 2) 
=MonthName(month(Now()) + 3) 
...
