To apply a workaround to the query and avoid using list comprehensions in
the MERGE clause, you can modify the query to precompute the list before using
it in the MERGE clause. Here's how you can rewrite the query:
WITH input_list AS (
SELECT [1,2,3] AS list
)
SELECT * FROM cypher('graph_name', $$
MERGE ({list: u.list})
ON CREATE SET ...
ON MATCH SET ...
$$) AS (a agtype);
In this modified query:
We first create a Common Table Expression (CTE) named input_list to compute
the list [1,2,3].
Then, we reference this computed list u.list within the MERGE clause.
You need to replace ON CREATE SET ... and ON MATCH SET ... with the
appropriate actions you want to perform when the MERGE clause creates or
matches a node.
By precomputing the list outside the MERGE clause, we avoid using list
comprehensions directly within it, potentially bypassing the error you
encountered.
