非常感谢您的帮助我不完全确定您想要什么，但每个“id”是否有一行？如果是的话
谢谢你宝贵的回复。在上面的查询中，我希望对获取SystemName和ObjectType做一点小小的更改。您发布的查询工作正常。但正如您所看到的，有些字段（SystemName和ObjectType）生成为NULL。例如。第一个DataObjectElement包含2个CollectionItem（604008604008A），但CollectionItem中没有“SystemName”，因此我希望主DataObjectElement标记中有SystemName。。这就是“会计关系”。ObjectType也是一样，有人能帮我回答上面的问题吗please@Arkesh没问题。如果这一切都完成了，请接受答案
