SQL Server 2005如何透视或跨标签数据来获得我的结果集？

Question

我正在寻找生成一个存储过程，将采取projectIds的CSV字符串并返回以下结果集。

sample data

的专案编号和名称字段来自工作表中，而其余字段是里程碑的枢轴为每个项目的日期。 （37,39,41,45,47,50,53,72,73,75,77）中，里程碑字段是CID的某些里程碑，我希望每个相应的里程碑都显示为excel文件中的名称（I猜对使用别名为每个每个里程碑名称转换什么，我想让它显示为）

另外要注意的第一个里程碑场是BRS（CID = 37）的开始日期和里程碑其余字段是所有结束日期，包括里程碑cid 37和上面提到的其余部分。

的日期应该代表那里获得的数据有projectMilestone日期，如果有特定CID没有projectMilestone然后我需要使用ReleaseSchedule日期。我要去COALESCE（projectmilestone日期，发布日期）来完成这个任务。

里程碑名的字段标题是这样的：如果

CID   NAME in result set (as field headers) 
37   BRS 
39   SRS 
41   SAD 
45   Product Profile Review 
47   SE Integration 
50   IDE 
53   UAT 
72   PE Testing 
73   Code Freeze 
75   Dark Pod 
77   Production

@beth我有这方面的工作（那种）现在个人projecttId与下面的代码。但不是使用主键我有手动的case语句来结束数据的枢轴转换：

ALTER PROCEDURE [dbo].[rpt_ReportingMilestones]

BEGIN 
    SELECT sco.CID, 
      sco.CodeName, 
      t1.EndDate as rsEndDate, 
      t2.EndDate as pmEndDate, 
    t2.CodeName as RAGStatus 
     INTO #TTT 
     FROM StatusCode sco 
     LEFT OUTER JOIN 
      (SELECT sc.CID, 
        rs.EndDate 
       FROM StatusCode sc 
      INNER JOIN ReleaseSchedule rs 
       ON sc.CID = rs.MilestoneCID 
      INNER JOIN Project p

     ON sco.CID = t2.CID

Answer 2

不知道你可以完全自动化你想要的一切。

重：我希望每个相应的里程碑显示为Excel文件名（我猜使用别名为每个每个里程碑名称转换什么，我希望它作为显示）

你可以使用查找表吗？

重：另外要注意的第一个里程碑场是BRS（CID = 37）的开始日期和全部结束日期

枢轴之前的里程碑其余字段，这些字段将必须在一个等效的输出列。在数据透视期间，您必须将聚合函数应用于值，如first（），min（）或max（）。

re：日期应该代表可用数据所在的projectMilestone日期，如果没有特定CID的projectMilestone，那么我需要使用ReleaseSchedule日期。

再次，您需要在数据透视之前完成此项工作。

您可以通过projectMilestone和releaseSchedule（仅适用于projectMilestone中的间隙）并查找要显示的列标题名称来获取未转换的结果集吗？
