有没有办法查询未来的SSRS订阅时间表？

Question

在我的办公室,我们许多人使用SSRS来安排重复报告.我想查看即将到来的报告运行的时间表,在接下来的几天或一周内,以便我们可以看到20个报告是否都将尝试同时运行.我怎么能做到这一点？我创建了显示订阅信息的t-sql报告,但它们只显示"上次运行"的日期和时间.这对预测明天的瓶颈没有帮助.解决方案也应该包括数据驱动的订阅.

Answer 1

SSRS将其所有数据存储在ReportServer数据库中,因此您需要一个对此数据库具有读访问权限的帐户.这与以纯模式运行的SSRS相关.我也不确定此代码是否会处理共享计划或数据驱动订阅,但我很确定它们会是.我只是没有测试过它们.

请注意: Microsoft不建议或支持直接查询ReportServer数据库.他们可以在下一个版本中更改结构或更新SSRS,您可能不会收到任何警告.Microsoft建议在需要查询有关报告服务的信息时始终使用SSRS Web服务.

这些是与提取订阅信息相关的表格:

• dbo.Catalog - 有关已部署报告的信息
• dbo.ReportSchedule - 与时间表和时间表相关的报告信息
• dbo.Subscriptions - 有关订阅的信息
• dbo.Schedule - 有关时间表的信息

下面的SQL提取所有报告的计划间隔信息.它不计算下一个运行日期,但通过计算运行计划的间隔,您可以编写另一个查询来生成实际日期.

此SQL最初是为报表编写的,该报表只显示描述间隔的字符串,因此最终输出可能不是您所追求的.它应该给你一个很好的起点,因为它确实找出了所有的间隔细节.
