Tsql 如何在不分组行数据的情况下将总计/小计添加到一组结果中？

我正在为业务报表构造一个SQL查询。我需要在报告中按文件号和总计对小计进行分组

我正在进入未知的SQL领域，所以这是第一次尝试。我提出的问题几乎奏效了。唯一的问题是条目正在分组-我需要在报告中将它们分开

以下是我的示例数据：

FileNumber Date Cost Charge 3 Dec 22/09 5 10 3 Jan 13/10 6 15 3B Mar 28/10 1 3 3B Mar 28/10 5 10 我得到以下信息：

FileNumber Date Cost Charge 3 Dec 22/09 5 10 3 Jan 13/10 6 15 3 NULL 11 25 3B Mar 28/10 6 13 <-- 3B NULL 6 13 NULL NULL 17 38 我想要的是：

我可以清楚地看到为什么要对条目进行分组，但我不知道如何将它们分开，同时仍然返回小计和总计

在做这样的高级SQL查询时，我有点生疏，因此如果我使用WITH ROLLUP解决问题的方法错误，请建议一些首选的替代方法-您不必为我编写整个查询，我只需要一些指导。谢谢

愚蠢的我。我只是通过在源表上使用UNIONALL和SELECT来尝试这一点。。。SUMCost…-你的解决方案比这更有效吗？@JonS:UNION需要两次通过，所以是的，这个解决方案更有效。
