Question

我写的以下查询正在努力。我发现的问题是每个泵，电缆等都可以在每个零件列中列出。例如：

我想得到的是每个泵，电缆等都列好的，而不是我目前得到的，这只是第一个泵，电缆等。

这是我正在运行的查询：

Pull Date| Well_Name | BODH1 | BODH1_PN | BODH1_SN | BODH2 | BODH2_PN | BODH2_SN

以下是我目前收到的一个例子：

我对SQL Server PIVOT不是很熟悉，或者在这种情况下甚至需要它。

我感谢您提供的任何帮助，并提前感谢您。

编辑：

不幸的是我无法添加我想要的图片，所以我会尝试解释它。

我想将它全部放在一行，所以看起来有点像这样：

@objc

泵，电缆，MLE等也会重复。我有20个部分的列，我想拉它们，所以我可以轻松地将pump1排序通过泵5（有些井有5个更少）。最终，这些数据将被插入到另一个表中以进行更新。

我将调查Dynamic Pivot以供日后使用，但这解决了我的问题（是的，它非常无聊和丑陋）：

Select Pull_Date, Well_Name,
          MIN(CASE WHEN Part1 ='BODH' THEN 'BODH' ELSE NULL END) [BODH1],
          MIN(CASE WHEN Part1 ='BODH' THEN Part1_PN Else NULL END) BODH1_PN,

 GROUP BY Pull_Date, Well_Name

我是否需要创建一个数据透镜，或者我可以更改此查询/添加了测试数据的链接
