Neo4j Cypher query to find node IDs for array of nodes

Question

I have a collection/array of nodes for which I want to find the nodeID for every node in the array. Something like this -

Foreach node in [Nodes] return ID(node)

To do what you asked you'd do:

UNWIND ["abc", "def"] as val
MATCH (n:<yourlabel> {Value: val}) //Where 'Value' is your property
RETURN ID(n)

This gets you the Neo4j ID of your nodes, but you should not use this to do anything with unless you really have good cause to.
