Sample graph: (to be used for the following examples)
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]"}])
Common Usage
Example: Find nodes of @professor, whose age is greater than 27
find().nodes({@professor && age > 27}) as n
return n{*}
|--------------- @professor --------------|
| _id | _uuid | age | email |
|-------|-------|-------|-----------------|
| P001 | 1 | 53 | [email protected] |
Analysis: This filter is equivalent to {@professor && age > 27}.
