我相信有很多与此错误相关的 StackOverflow 帖子，但似乎没有一个有我正在寻找的简单解决方案。如果你们中的任何人能调查一下，我将不胜感激。
问题：我正在使用一个动态 sql 存储过程，它在 cte 表达式中使用 FundTransfer 数据库表，然后与 WebbnkDb 数据库连接。
但是，我遇到了上面标题中提到的异常。如果我删除WITH EXECUTE AS SELF命令一切正常，但不幸的是我无法摆脱它，因为它用于某些安全原因。请用简单的话建议我解决方案。

I have to create new version of this store procedure since we continue making changes to resolve helpdesk tickets and
