在SDE数据库Python中识别不活动/未使用的域

我一直在搜索工具/脚本论坛，以便能够识别sde数据库中正在使用的域和未使用的域。我遇到了一个py脚本工具，该工具非常适合.gdb，但在.sde上尝试时却不断出现错误。

del cursor, table, fields

在sde上尝试使用此工具时，我不断遇到的错误如下：

Failed script exportDomainProperties...

Traceback (most recent call last):
 File "D:\Downloads\exportDomainProperties\exportDomainProperties.py", line 55, in <module>
  arcpy.CreateTable_management(output_workspace,"cv_" + d.name + _details","#","#")

正如我所说的，它可以在.gdb上完美运行，并且domainProperties输出表正是我要用来标识正在使用和未使用的域的内容。我对PY一无所知，因此该脚本非常适合作为工具添加。请PYTHON脚本编写者帮我解决这个问题。

谢谢

答案 0 :(得分：0)

我知道了，这与SDE无关。 SDE数据库具有一个名为No / Yes的域，并且由于字符/而引发错误，一旦将其删除，脚本将按预期运行。
