startNode() returns the end node of a relationship.
Syntax: startNode(relationship)
Returns: A Node.
Arguments
| Name | Description |
| relationship | A numeric expression. |
Example
CREATE (:Person {name:"Elon Musk"})-[b:FATHER_OF]->(:Person {name:"X Æ A-12 Musk"})
RETURN startNode(b)
The value returned will be start-node of the relationship b. Which in this case will be-
{
"name": "Elon Musk"
}
Considerations
startNode(null)returnsnull.
Example
CREATE (:Person {name:"Elon Musk"})-[b:OWNS]->(:Company {name:"SpaceX"})
RETURN startNode(b)
Returns the following Result
startNode(b) |
{"name": "Elon Musk"} |
Example
CREATE (:Person {name:"Elon Musk", birthplace:"South Africa", profession:"Entrepreneur"})-[b:OWNS]->(:Company {name:"SpaceX"})
RETURN startNode(b)
Returns the following Result
startNode(b) |
{"name": "Elon Musk","birthplace": "South Africa","venue": "Entrepreneur"} |
Example
CREATE (:Person)-[b:OWNS]->(:Company {name:"SpaceX"})
RETURN startNode(b)
Returns the following Result
startNode(b) |
{} |
Note– The end-node for the relationship b does not have any properties, and for that reason an empty map(representing a node) is returned.
Example
MATCH(:Person)-[b:OWNS]->(:Company {name:"SpaceX"})
RETURN startNode(b)
This query is similar to the query above it, just that it searches for existing patterns in the databases instead of creating them. This query returns the following result, similar to the above query.
startNode(b) |
{} |
Example
RETURN startNode(null)
Returns the following Result
startNode(null) |
null |
