Re: [clojure-neo4j] How to Match by Label with {_variable}? re:necons tquery:

[Rohit Aggarwal]

Stefan's answer on SO is the correct one. You can't parameterize on the label. More about it here:

http://neo4j.com/docs/2.2.6/cypher-parameters.html

For matching by a label and a variable, you'll have to create something like this:

(cy/tquery conn "MATCH (n:Folder) WHERE n._nodeid = {_nodeid} RETURN n;" {:_nodeid _nodeid})

Hope this helps.

I am trying to use clojure neocons to perform a cypher query where I need to use a variable placeholder for the label:

(def node-query "MATCH (n:{_nodetype})
                 RETURN n;")

I am getting an error when I add {_nodetype} but no error when I remove {_nodetype}

"Invalid input '{': expected whitespace or a label name (line 1, column 10 (offset: 9))\\n\\\"MATCH (n:{_nodetype})\\\"\\n ^\",\n \"exception\"...

Here is my call to tquery:

(cy/tquery conn node-query {:_nodeid _nodeid :_nodetype "Folder"})

What is the cypher / neocons syntax to MATCH by label with a variable?

I am very grateful for help you could suggest.

But of course can replace it in clojure
