Hello, I've looked for some info but I couldn't find anything clearly explained. My question is
*How do I make a Edge unique in Orientdb ? version 1.7* The solution that I came up with: - delete the edge - create it again but it's not nice. Edge is without any properties. *Example:* create edge is_friend from #12:0 to #12:3 and if I call it again, there should be an error like when you make a unique index. Lvca said Create a constraint on Edge out and in fields. But how exactly to do it ? I have a simple database with users and edges "is_friend" from user to user without any additional properties on the edge. http://www.orientechnologies.com/docs/last/orientdb.wiki/Graph-Schema.html#constraints Thank you very much -- --- You received this message because you are subscribed to the Google Groups "OrientDB" group.
