Question

我希望，你可以帮助我对于更大的SQL查询，我不是很熟练，所以我无法在大约5到6个小时内解决问题：/

在SQL Server 2008上，我收到此错误：

列'pvtMonth.1'是   在选择列表中无效，因为它不包含在任何一个中   聚合函数或GROUP BY子句。

列名称'j_sumzeit'无效。

列名称'j_sumzeit'无效。

我的查询：

包含一些示例数据的表格

表结构非常糟糕，但我无法更改它们，因为它们来自外部公司。

|-----------------------------------------------|

| 7               | 450             | KstTst1           |

结果应如下所示（数字可能与上述示例数据不同）

Answer 1

如果没有看到初始表结构，很难说。尝试在SELECT中插入“j_sumzeit”列（刚好在第一个FROM之后）。

PIVOT和联接的问题
