我正在通过 SQL Server 迁移助手 (SSMA) 将 Access 数据库中的表迁移到 SQL Server。我遇到了一个奇怪的查询，它在数据库的原始版本中成功运行，使用本地表，但不在迁移的数据库中，链接表链接到 SQL Server 后端数据库。
在迁移的数据库中，当我尝试运行查询时，我收到一条错误消息：“定义的字段太多”。
我的问题是：为什么这个查询应该使用本地表运行，但由于链接表的字段太多而失败？
该查询明确列出了字段，它不使用 SELECT *。根据我的统计，查询中有 69 个字段，尽管其中有几个是计算字段，每个基础表中总计有 14 个字段。
我在这里读到的一篇论坛帖子建议 Access 计算表中的基础字段或连接以进行查询的查询。那是对的吗？如果是这样，这可能是问题的原因，因为迁移过程会将 SSMA_TimeStamp 列添加到迁移的表中。如果这是问题所在，有人知道解决方法吗？将一些计算字段拆分到另一个查询中并从该新查询中读取？
这是查询：

我将是第一个承认查询是野兽的人，但我正在尝试迁移数据库而不从头开始重写所有内容，因为几个月后 Access 前端将被基于 Web 的应用程序取代。
