Sample graph: (to be used for the following examples)
Run below UQLs one by one in an empty graphset to create graph data:create().node_schema("professor").node_schema("student")
create().node_property(@*, "age", int32).node_property(@*, "email", string)
insert().into(@professor).nodes([{_id:"P001",_uuid:1,age:53,email:"[email protected]"},{_id:"P002",_uuid:2,age:27,email:"[email protected]"}])
insert().into(@student).nodes([{_id:"S001",_uuid:3,age:27,email:"[email protected]"},{_id:"S002",_uuid:4,age:20,email:"[email protected]"},{_id:"S003",_uuid:5,age:25,email:"[email protected]"}])
Property
Example: Find nodes whose age is in the open interval [25, 35]
find().nodes({age <> [25, 35]}) as n
return n{*}
