i have created a new node labeled User
CREATE (n:User)
i want to add a name property to my User node i tried it by
MATCH (n { label: 'User' })
SET n.surname = 'Taylor'
RETURN n
but seems it is not affecting .
how can i add properties to a already created node .
Thank you very much.
Your matching by label is incorrect, the query should be:
MATCH (n:User)
SET n.surname = 'Taylor'
RETURN n
What you wrote is: "match a user whose label property is User". Label isn't a property, this is a notion apart.
As Michael mentioned, if you want to match a node with a specific property, you've got two alternatives:
MATCH (n:User {surname: 'Some Surname'})
or:
MATCH (n:User)
WHERE n.surname = 'Some Surname'
Now the combo:
MATCH (n:User {surname: 'Some Surname'})
SET n.surname = 'Taylor'
RETURN n
