问题描述
看来，OrientDB 3.0.4中的控制台应用程序与OrientDB 3.0.2不能向后兼容，以创建具有EMBEDDEDLIST的顶点.
It appears that console application in OrientDB 3.0.4 is not backward compatible with OrientDB 3.0.2 for creating Vertex having EMBEDDEDLIST.
在OrientDB 3.0.4控制台中，以下查询失败:
Following Query fails in OrientDB 3.0.4 console:
CREATE VERTEX Profile SET name = "John", phone = [{ "@type":"d", "number" : "212" }]
如何解决该问题?v3.0.4做了哪些更改?在哪里可以找到更新的文档?
How can I resolve the issue?What are the changes for v3.0.4 and where can I find updated documentation?

推荐答案
问题是您已将属性声明为"电话"，然后尝试使用小写的名称"电话"，与架构不匹配.此外，也不需要使用方括号，因此请尝试使用以下命令代替最后一个查询:
The issue is that you've declared your property as "Phone" and then you're trying to create your vertex using the name "phone" in lowercase which doesn't match the schema.Also there's no need to use square brackets so instead of that last query, try using:
CREATE VERTEX Profile SET name = "John", Phone = { "@type":"d", "number" : "212"}
