title: Having an issue with Neo4j
body: <pre><code>MATCH (n:CALLS { compileunit:'Way-Duy_User-Task-Manager.2020-11-12.java', release:1})-[*]-&gt;(b)  
  set n.szDet_t = sum(b.szDet)
  return n, sum(b.szDet) as DET  
  </code></pre>
  <p>The above mentioned code is not working, although similar lines are functioning perfectly.</p>
  <p>This gets the right value but does NOT update det.</p>
  <pre><code>MATCH (n:CALLS { compileunit:'Way-Duy_User-Task-Manager.2020-11-12.java', release:1})-[*]-&gt;(b)  
  return n.Label, sum(b.szDet) as DET  
  </code></pre>
  <p>I would appreciate help in getting this to work. This is Neo4j cypher.</p>
