我有一些数据,我需要支点(我相信),并阅读了许多关于如何做到这一点的文章。我甚至实现了一个有助于处理动态列(这是我需要的)的方法,但是,我只能得到一个字段来填充最终结果。
这是我当前的结果集,在旋转之前:

这是期望的结果(在pivot或其他什么之后):

我的基本查询是:

SELECT
   (SELECT Value FROM dbo.ParseDelimetedString(st.CMA_CODE, 1, default)) + '-' + (SELECT Value FROM dbo.ParseDelimetedString(st.CMA_CODE, 2, default)) AS ACCNumber,
   (SELECT Value FROM dbo.ParseDelimetedString(st.CMA_CODE, 3, default)) AS Modification,
   OS_NUMBER,
   VIS_GRADE
FROM
   SupportingEngineTest AS st
WHERE
   FINAL_FORMULA_ID = 9477

我现在的动态轴心是:

DECLARE @Columns AS VARCHAR(MAX)

SELECT @Columns = COALESCE(@Columns + ', ', '') + QUOTENAME(ACCNumber)
FROM (
   -- Distinct ACC Numbers
   SELECT DISTINCT
          (SELECT Value FROM dbo.ParseDelimetedString(st.CMA_CODE, 1, default)) + '-' + (SELECT Value FROM dbo.ParseDelimetedString(st.CMA_CODE, 2, default)) AS ACCNumber
   FROM
          SupportingEngineTest AS st
   WHERE
          FINAL_FORMULA_ID = 9477
) AS Distincts
ORDER BY
   Distincts.ACCNumber

DECLARE @SQL AS VARCHAR(MAX)

SET @SQL = 'SELECT Modification, ' + @Columns + '
FROM (
   SELECT
          ROW_NUMBER() OVER(ORDER BY st.CMA_CODE ASC) AS RowNumber,
          st.CMA_CODE,
          (SELECT Value FROM dbo.ParseDelimetedString(st.CMA_CODE, 1, default)) + ''-'' + (SELECT Value FROM dbo.ParseDelimetedString(st.CMA_CODE, 2, default)) AS ACCNumber,
          (SELECT Value FROM dbo.ParseDelimetedString(st.CMA_CODE, 3, default)) AS Modification,
          OS_NUMBER,
          VIS_GRADE
   FROM
          SupportingEngineTest AS st
   WHERE
          FINAL_FORMULA_ID = 9477
) AS PivotData
PIVOT (
   MIN(RowNumber)
   FOR ACCNumber IN (' + @Columns + ')
) AS PivotRessult
ORDER BY
   Modification'

EXEC(@SQL)

输出为:

我添加了 RowNumber 以及 CMA_CODE 我可以集中精力,但都没用。我用过 ACCNumber 在聚合中,并确保它向我显示该值,但我不确定如何让其他每个字段都显示在结果中。
