:param node_id : 'id'

with $node_id as par

match (u:User) where u[par] is not null with u,par

with apoc.map.fromLists(

[par],

[u[par]]

) AS output

CALL apoc.merge.node(

["child"],

output

) yield node return node

You can use 'unwind' with a list of parameters to execute your script for each parameter in the list. The following is an example, although this script is not making sense as it is written. Can you provide a description of what you are trying to do?

unwind $node_id_list as par
match (u:User) where u[par] is not null 
with apoc.map.fromLists([par],[u[par]]) AS output
CALL apoc.merge.node(["child"],output) yield node 
return node
