查询以查看类属性

[英]query to see class attribute

Is there a SQL syntax to see the value of an class attribute using WebUI of OrientDB ? 是否存在SQL语法,才能使用OrientDB的WebUI查看类属性的值?

I can use the following to edit the value : ALTER CLASS Employee CUSTOM minAge=16 ( doc ) But I can't find a way to check out the value set. 我可以使用以下内容来编辑值: ALTER CLASS Employee CUSTOM minAge=16doc )但是我找不到方法来检查值集。

I can do that using Java API : graph.getVertexType("Employee").getCustom("minAge") I need this as a SQL query. 我可以使用Java API来做到这一点: graph.getVertexType("Employee").getCustom("minAge")我需要将此作为SQL查询。

my orientdb version : 2.1.19 我的orientdb版本:2.1.19

Try this: 尝试这个:

SELECT FROM (
   SELECT expand(classes) from metadata:schema
) WHERE name = 'theClassName'

OrientDB v 2.1.x is not supported anymore, I strongly suggest you to upgrade to v 3.0 OrientDB v 2.1.x不再受支持,强烈建议您升级到v 3.0
