寻求退出循环的帮助
Looking for help exiting out of loop
我一直在努力复制 AutoSys 的 Box 功能。我遇到了此处显示的解决方案 (https://dba.stackexchange.com/a/161658)，它非常非常有效。我开始添加它，检查结果，并添加我们使用的另一个 ETL 解决方案的处理。
我 运行 遇到麻烦的地方是，当我意识到没有检查工作是否有效时。我想检查一下，以防工作名称拼写错误，或者有人删除了工作。如果没有，我不想假设正在执行一项工作。我添加了对有效 SQL 代理作业名称的检查。如果作业名称有效，则此方法有效。但是，如果作业名称无效，该过程将陷入循环并显示错误消息 'NO JOB'，直到我停止该过程。

我想要发生的是：当它检查有效的作业名称时，打印 NO JOB 并结束，它应该转到第 378 行，将 1 添加到 @JobNumber，结束该轮，转到下一个作业。
我不明白为什么它会卡在循环中。
感谢您的帮助。
由于您的循环很长且包含嵌套块且难以调试，我将执行以下操作：
- 在进入循环之前，验证缺少哪些作业
- 创建一个 table 来保存丢失的工作，例如@MissingJobs，在你处理现有工作之前用它们做你的事情
- 基于@MissingJobs 从@JobList table 中删除缺失的作业，然后循环遍历这些作业，因此在这种情况下无需调试长循环块。或者创建一个新的 table 如果您需要原始文件并在循环中使用它 - 但在这种情况下，需要做更多的工作才能从 @JobList 更改为新文件。如果将所有减少的@JobList 与@MissingJobs 联合，您可以取回原始列表。无论如何，您需要删除 --VALID JOB 之后的块？ （直到 PRINT 'YES WE FOUND THE JOB';）因为你可以根据这个逻辑打印出来 - 在这种情况下你还必须在 SET @JobNumber = @JobNumber + 1; 之后删除一个 END;因为你删除了一个未关闭的 ELSE BEGIN。
