These files hold the info about the terminals..Every day I sift through these same 60 files and look to make sure #2 in the TermName field is set to Backup in the Role field, and also that no other Terms have the Role backup in the field.I would really love some direction to take on how to make a query output a "REDFLAG" if you will, pointing out that a sertain table is not how it should be.I hope this makes sense. Ill explain anything better that anyone wants me to.Thanks a ton in advance!推荐答案 heyy我愿意做任何必要的事情，数据库只用于此功能。 有时这些位置有两个终端设置为备份，有时它们没有备份。 我需要它能够运行它并让它返回任何不是应该如何，所以我可以给他们发电子邮件，告诉他们解决它。是否他们备份了两个终端或备份没有终端。 如果有帮助，我甚至会在互联网上发布这个数据库... 请回复我！ 谢谢！heyy I would be willing to whatever is necessary, the database is only being used for this function.Sometimes these locations have two terminals set as backup, and sometimes they dont have a backup.what I need it to be able to run it and have it return anything that is not how it should be so I can email them and tell them to fix it. whether that be they have two terminals on back up or none on backup.Ill even post this database on the internet if that helps...Please get back to me!thank you! 展开 | 选择 | Wrap | 行号 这篇关于帮助编写多表查询的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
