Question

我尝试过使用CTE，但一直无法弄明白。我想将多行更改为一行，其中包含多个列。任何方式去做...

当前结果

ern CostPool
111 NULL
111 5

期望的结果

ern CostPool1   CostPool2
111 NULL        5

, [RMTS, Support, or Partial Quarter], SUM(CAST([Staff Employment Status] AS INT)) sumEmpStatus, SUM(CAST(countisMHy AS INT)) sumcountisMHy, SUM(CAST(sumisMHy AS INT)) sumisMHy1

您可以尝试使用 Pivot 运算符将行转换为列。

https://technet.microsoft.com/en-us/library/ms177410(v=sql.105).aspx

该方法可行，尽管您的示例数据和预期结果与您发布的大量查询不完全匹配，因此在您提供更多测试数据/预期输出（和表模式）之前，我无法提供更具体的示例。 p>

如何将这些更改为列？
