2005 SSRS/SQL Server PIVOT 结果需要反转

Question

序言：我已经阅读了三个问题/答案here,here, 和here，对@cade-roux 大加赞赏。这一切都源于试图在 2005 年 SSRS 矩阵中使用以下数据，我相信这不起作用，因为我想展示一个必须多次参加测试的成员，而 SSRS 似乎需要我想要的聚合显示所有日期。

我在表格中得到以下结果，似乎正确显示了所有数据：

如何更改下面的代码以显示 a) 每列顶部的“测试”以及 b) 如果需要，显示测试的多个日期？

这是我必须在上面生成表格的代码。大部分内容都被注释掉了，因为我只是想让枢轴工作，但您可能会注意到我也在尝试指定哪个测试列先出现。

    CREATE TABLE #tmp (     ---THIS WORKS BUT TESTS ARE VERTICAL
    [TEST] [varchar](30) NOT NULL,
    [ED] [datetime] NOT NULL
)

--WHERE THE TEST AND ED COME FROM
INSERT #TMP

编辑： 目标是让 SSRS 中的报告如下所示：

Answer 1

我能够通过在 PIVOT 运算符下方的查询中添加一个数字 (RowNum) 来生成您正在寻找的结果。它不必在最终查询中（尽管您可能希望它用于客户端排序），但是通过将它放在底层，PIVOT 操作将该数字视为 GROUP BY 子句的成员。

请查看下面我的示例 SQL，如果这符合您的条件，请告诉我。

CREATE TABLE #TMP
  (
    Name VARCHAR(10),
    Test VARCHAR(20),
    EffectiveDate DATETIME
  )
INSERT INTO #TMP (Name, Test, EffectiveDate)
SELECT 'Jane', 'NM_Course1', '01/17/2014' UNION
SELECT 'Jane', 'NMEP_Course1', '12/19/2013' UNION
SELECT 'Jane', 'NMEP_Course1', '12/20/2013' UNION
SELECT 'Jane', 'NMEP_Course2', '12/19/2013' UNION
SELECT 'Jane', 'NMEP_Course2', '12/22/2013' UNION
SELECT 'Jane', 'NMEP_Course2', '01/05/2014' UNION
SELECT 'John', 'NM_Course1', '01/17/2014' UNION
SELECT 'John', 'NMEP_Course1', '01/11/2014' 



DECLARE @sql AS varchar(max)
DECLARE @pivot_list AS varchar(max) -- Leave NULL for COALESCE technique
DECLARE @select_list AS varchar(max) -- Leave NULL for COALESCE technique

SELECT @pivot_list = COALESCE(@pivot_list + ', ', '') + '[' + CONVERT(varchar, PIVOT_CODE) + ']'
        ,@select_list = COALESCE(@select_list + ', ', '') + '[' + CONVERT(varchar, PIVOT_CODE) + '] AS [col_' + CONVERT(varchar, PIVOT_CODE) + ']'
FROM (
    SELECT DISTINCT PIVOT_CODE
    FROM (
        SELECT TEST AS PIVOT_CODE
        FROM #tmp
    ) AS rows
) AS PIVOT_CODES

SET @sql = '
SELECT Name, ' + @select_list + '
FROM 
  (
    SELECT b.Name, RowNum, b.EffectiveDate, b.TEST AS PIVOT_CODE
    FROM 
          (
            SELECT Name, Test, EffectiveDate, ROW_NUMBER() OVER (PARTITION BY NAME, TEST ORDER BY EffectiveDate) RowNum 
            FROM #Tmp
          ) b
  ) p
PIVOT (
    MIN(EffectiveDate)
    FOR PIVOT_CODE IN (
        ' + @pivot_list + '
