Hi,
I am using orinetdb 1.7-rc2 and need some information about cleanup of
edges. I have a user and group vertex and using an edge to link users with
the group.
I am creating user as
insert into user set name = 'test'
and similarly group as
insert into group set name = 'test_group'
Now if a user wants be a part of group, I am using an edge to link them
create edge userIngroup from user to group;
My edge has following properties as, I dont't want multiple edges between
same vertexes
'CREATE PROPERTY UserInGroup.in LINK Group',
'CREATE PROPERTY UserInGroup.out LINK User',
'ALTER property UserInGroup.out MANDATORY=true',
'ALTER property UserInGroup.in MANDATORY=true',
'CREATE INDEX UniqueUserInGroup on UserInGroup(out, in) UNIQUE',
Now if I delete a vertex either by using "delete from" or "delete vertex",
it does not remove the edge.
Lets say I executed
delete vertex user where name = 'test'
The edge still remains but if I execute
select expand(in('UserIngroup')) from group
It gives an error.
SEVE Internal server error:
java.lang.NullPointerException [ONetworkProtocolHttpDb]
How can I remove all the edges when a vertex is deleted. Can this be
handled through orinentdb
P.S: I am using Orientdb REST API to execute these sql
Regards,
Munish
