我正在尝试优化我构建的 SQL 查询，我将其用作 Access 中的直通查询。目前，此查询最多可能需要 10 分钟才能完成，我真的很想缩短这个时间。我意识到问题的很大一部分是我在其他内部查询中有很多内部查询。这是因为我的公司不会授予我创建任何永久表的权限。
我有一个此查询的版本，其中我将大量“混乱”的内部查询转移到临时表并调用它，但这不能作为 Access 的直通查询。除非它在访问数据库打开时的每个会话期间运行。
我真的很想尝试找到一种方法，让这项工作就像 SQL 中的直接查询一样，我可以将其用作 Access 中的直通。
这是 SQL：

下面应该稍微整理一下代码。
此外，所有日期的数据类型和格式是什么。迄今为止的所有转换和日期时间都没有帮助。
