在报告中显示 Cube 的最后处理时间

Question

有什么方法可以显示上次在报表中处理多维数据集或维度的时间（我正在使用报表生成器）？

我尝试通过开始创建一个名为 LastProcessTime 的表，其中包含“Type”和“DateTimeProcessed”字段，并且我可以插入到该表中，但我不知道如何启动插入。也许有一种完全不同的方法。谢谢。

Answer 1

不确定您是否可以将其添加到报告生成器中，但尝试标准 MDX 报告，并使用 SSAS DMV（动态管理视图）：

在 MDX 查询窗口中针对多维数据集运行此命令（我知道，它看起来确实像 TSQL）：

SELECT * FROM $system.mdschema_cubes

应该为您提供所需的内容吗？

Answer 2

我知道有点晚了 - 但您可以在 SSAS 中使用自定义存储过程通过普通成员公开此信息

with 
     member [Measures].[LastProcessed] as ASSP.GetCubeLastProcessedDate()
select 
     [Measures].[LastProcessed] on 0
from [Your Cube]

这些信息可从 CodePex：分析服务存储过程项目，
