Question

我正在编写一个脚本，该脚本连接两个要素图层并基于另一个表中的字段更新一个表中的字段，以在ArcMap的Python shell中运行。每个图层的表包含约60,000个条目。

第一个要素层称为评估者表，我将其与第二个要素层称为宗地表结合在一起。我的脚本使用Update Cursor根据评估器中的字段来计算可包裹中的字段。 UpdateCursor脚本来自于本指南：https://community.esri.com/blogs/richard_fairhurst/2014/11/08/turbo-charging-data-manipulation-with-python-cursors-and-dictionaries

但是，当我运行脚本时，出现以下错误。

错误：

运行时错误追溯（最近一次通话）：在第78行的文件“”中 TypeError：无法更新联接表

我不知道如何解决此问题，并且在学习使用ArcMap中的Python编码时还很陌生。任何帮助将不胜感激！
