TropicalPenguin opened a new issue, #343:
URL: https://github.com/apache/age/issues/343

   **Is your feature request related to a problem? Please describe.**
   Currently, the AGE implementation of the Cypher SET clause expects a 
variable name.
   
   If a variable name isn't provided, the following error is currently noted:
   `ERROR:  SET clause expects a variable name`
   
   This means that if I want to copy all properties from one entity to another, 
I would need to know all possible properties by name before creating a given 
query. An example of where this can be useful is renaming a relation in a 
single query.
   
   **Describe the solution you'd like**
   The same SET syntax [used by 
Neo4J](https://neo4j.com/docs/cypher-manual/current/clauses/set/#set-copying-properties-between-nodes-and-relationships)
 and [RedisGraph](https://github.com/RedisGraph/RedisGraph/pull/2051) 
   
   **Describe alternatives you've considered**
   Querying all properties in first query, using results from first query to 
create a second query containing the SET clause.
   
   **Additional context**
   I created a similar request [for 
RedisGraph](https://github.com/RedisGraph/RedisGraph/issues/2045) last year, 
and they found it pretty trivial to support.
