SQL Server 2012将数据从一列拆分为多列

我有三列很长的数据，如下所示。

数据以214行块的形式添加到数据库中，每行都是该时间戳处不同变量的值。每个数据块214行中的每一行的时间戳都相同。我试图将这些块分解成单独的列/行（如果可能的话，我希望这是动态的，而不是输入列或行的每个名称）

下面的任何一种解决方案都有效

我曾研究过使用PIVOT，但这似乎需要对数据进行算术组合，而不仅仅是将其拆分为单独的列/行

这将用于生成一个SQL报告，该报告大约每月查看一次，因此性能并不是什么大问题

上面代码的问题是，我在一些标记名中使用了特殊字符“[”和“]”，这导致sql出错。删除这些字符会使代码正常工作

A将完成这项工作，以防您还不知道所有可能的

TagItemIDs

。如果你这样做了，一个简单的枢轴也会起作用

示例代码：

declare @cols_tagItems as nvarchar(max)
     ,  @cols_tagItems_max as nvarchar(max)
     ,  @query  as nvarchar(max)

select @cols_tagItems = stuff((select distinct ', ' + TagItemID from #table for xml path(''), type ).value('.', 'nvarchar(max)') ,1,1,'')
 select @cols_tagItems

set @query = 'select TagTimestamp, ' + @cols_tagItems + '
                  from 
                    (
                        select TagTimestamp, TagItemID, TagValue
                        from #table

                  pivot ( max(TagValue) for TagItemID in (' + @cols_tagItems + ') )p  
              order by TagTimestamp'
