我有一个表，其中包含表中的 2 个 cr 记录。我正在尝试根据月份和年份进行分区。

我尝试创建此表的文件组，但在我的场景中，该表在预编码部分的许多地方都使用。有什么办法可以让我对这个表进行分区并在 BI 报告中使用它，这样预编程就不会产生影响。

对于版本： - 我有以下非常基本的查询，但需要 10 分钟才能运行。

这是执行计划 - https://www.brentozar.com/pastetheplan/?id=B1dy0ZQ6d

任何人都可以看到改进它的方法吗？让我知道一些示例数据/表结构是否有用。

您可以在没有多个文件组的情况下进行分区。理想情况下（出于性能原因）每个分区应该位于不同驱动器上的不同文件组上。但是分区可以正常工作（如果分区很大，则通常会更慢_在单个文件组上。以后在文件组之间移动分区很容易。
