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

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

  • MATCH (n:User) WHERE n.firstname = 'Andres' SET n.surname = 'Taylor' RETURN n – Michael Hunger Jun 25 '14 at 11:52

    or MATCH (n:User {firstname:'Andres'}) SET n.surname = 'Taylor' RETURN n – Michael Hunger Jun 25 '14 at 11:52
