我有一个表作为 MarketOutput 有 20 列
[Region] [LOB] [GWP 2013] [GWP 2014] [LR 2013] [LR 2014]
-------------------------------------------------------------
North Workers 38902.50 37,972,404 89 82
我想将列动态更改为行。Region 和 LOB 是固定列，[GWP 2013], [GWP 2014], [LR 2013], [LR 2014] 是动态列。
明年他们将是[GWP 2015]，[LR 2015]
我想取消旋转列并将 [GWP 2014] 拆分为两列 [GWP], [2014]。
输出应该是这样的
Region [LOB] [Metrics] [Year] [Value]
--------------------------------------------------
North Workers GWP 2013 38902.50
North Workers GWP 2014 37,972,404
North Workers LR 2013 89
North Workers LR 2014 82
你能建议如何做到吗？
我是在 SQL Server 中进行透视的新手
我还想每次使用动态列表将输出插入到新表中
