有人可以就如何将分配表格转换为目标表格提供一些帮助：

我只能在同一年的1月2月到12月。从去年11月开始，不知道如何连续两年制作它们。

关键问题是如何将当前表转换为目标表。在目标表中，例如2008年11月12月和2009年1月2月3月4月5月6月7月8月9月应显示在同一行中。此外，还要添加每列的总和以及每行的总和。
欢迎任何建议。
如果有人可以帮助我实现这一目标，我将非常感激。

这是完整的解决方案，您可以检查代码并在SQLFiddle Demo上进行检查，我将在代码下面做一个简短的解释。

首先，CTE将转移您的数据并创建11月，12月等列。此处的数据仍未分组。每个原始行都有一个单独的行，其值仅在一个月内，而在其他行中为零。使用简单的CASE声明（月份+ 1，月份＆lt; 11），可以实现明年1月至10月的月份。
第二个CTE正在对数据进行分组，并使用WITH ROLLUP提示创建小计。它只返回你想要的东西，只需要几个额外的行（每个SA的小计，项目组合，每个SA和总计）。
最终查询只是消除那些行并格式化几行和列以匹配您的目标表。
请注意，我手边没有SQL Server 2005来测试它，但我几乎肯定它应该可以正常工作
