我希望使用t-sql从ReportServer.dbo.Schedule表中提取“人类可读”的日程安排信息。
以下是“人类可读”的一个例子。
At 6:02 AM every Sun, Mon, Tue, Wed, Thu, Fri, Sat of every week, starting 2/28/2011
表格中有很多数字字段用于存储日程安排，但我想将这些字段转换为单词，如我的例子所示。
有没有人用报告服务做过这个？

SQL不适合字符串操作或按位操作，解析此表需要两者兼得。我确信SSRS不会在SQL中执行此操作：我可能在一半的时间内编写了这个，在C＃中编写了一半。

这篇文章可能很老了，但今天帮了我！ 我在Jamie F的CTE上发现了两篇我想补充的文章。
第31天缺少一个需要作为EnhancedSched CTE的一部分添加的条目，下面需要添加到'DaysOfMonthString'的末尾
+ CASE WHEN DaysOfMonth & 1073741824 <> 0 THEN '31,' ELSE '' END
此外，带有模12的'StartTime'列定义使任何时间从12开始为零，因此普通英语结果显示下午12:30的开始时间为下午12:30。 替换
CONVERT(VARCHAR, DATEPART(hour, StartDate) % 12)
与
CASE CONVERT(VARCHAR, DATEPART(hour, StartDate) % 12) WHEN 0 THEN '12' ELSE CONVERT(VARCHAR, DATEPART(hour, StartDate) % 12) END
让英文简单的开始时间正确阅读。
Mega感谢上面的Jamie F的帖子，保存了我的培根。先生为您提供+1互联网。
