It seems you're trying to execute Cypher queries within a PostgreSQL
environment using the cypher function. The error you're encountering is due to
the incorrect usage of the '|' symbol in the label definition within your MATCH
clause. In Cypher, '|' is not used to denote multiple labels for a node.
Instead, you should use the IN keyword.
Here's the corrected version of your first query:
sql
Copy code
SELECT * FROM cypher('playground', $$
MATCH (n)
WHERE n:Movie OR n:Person
RETURN n
$$) AS (v agtype);
This query will match nodes that have either the label 'Movie' or 'Person'.
Alternatively, you can use your second query as you provided:
sql
Copy code
SELECT * FROM cypher('playground', $$
MATCH (n)
WHERE label(n) = 'Movie' OR label(n) = 'Person'
RETURN n
$$) AS (v agtype);
Both queries should achieve the same result, with the second one explicitly
checking the labels of nodes. Choose whichever you find more readable or
preferable for your use case.
