reporting-services - SSRS 2008 R2 从 ReportServer DB 获取人类可读的计划信息

Question

我希望使用 t-sql 从 ReportServer.dbo.Schedule 表中提取“人类可读”的计划信息。

以下是“人类可读”的示例。

At 6:02 AM every Sun, Mon, Tue, Wed, Thu, Fri, Sat of every week, starting 2/28/2011

表中有一堆数字字段用于存储时间表，但我想将它们转换为单词，如我的示例所示。

有没有人用报告服务做过这个？

Answer 1

SQL 不太适合字符串操作或按位操作，解析此表需要两者兼而有之。我确信 SSRS 在 SQL 中不会这样做:我可能用 C# 一半的时间和一半的行来编写它。
