在我的办公室中，我们许多人使用SSRS安排定期报告。我想查看接下来几天或一周内即将运行的报告的时间表，以便我们可以查看是否有20个报告都将尝试同时运行。我该怎么做？我创建了显示订阅信息的t-sql报告，但它们仅显示“上次运行”的日期和时间。这对于预测明天的瓶颈没有帮助。该解决方案也应包括数据驱动的订阅。
最佳答案
SSRS将其所有数据存储在ReportServer数据库中，因此您将需要一个对该数据库具有读取访问权限的帐户。这与以纯模式运行的SSRS有关。我也不确定共享时间表或数据驱动的订阅是否将由此代码处理，但我很确定它们会得到处理。我只是没有测试他们。
请注意: Microsoft does not recommend or support directly querying the ReportServer database.他们可能会在下一版本或更新的SSRS中更改结构，并且您可能不会收到任何警告。 Microsoft建议在需要询问有关报告服务的信息时始终使用SSRS web service。
这些是与拉出订阅信息相关的表:
下面的SQL提取所有报告的计划间隔信息。它不会计算下一个运行日期，但可以通过计算出计划运行的时间间隔，可以编写另一个查询来生成实际日期。
该SQL最初是为报表编写的，该报表仅显示描述间隔的字符串，因此最终输出可能不是您想要的。尽管它确实可以找出所有间隔细节，但它应该为您提供一个良好的起点。
