As mentioned in #514, in
clauses seem to expect the postgres jsonb type. This breaks queries of the form
WHERE ALL(
r in relationships(p) WHERE ((type(r) = 'Contributes') OR (type(r) = 'Produces'))
)
You can cast the result of relationships()
function with the postgres function to_jsonb
but this then means the wrong type argument is being passed to type()
. The required query also requires a mix of postgres SQL and cypher rather than pure cypher.
For context, this was discovered in an attempt to work around the lack of support for (a)-[r:TYPE1|TYPE2]->(b)
.
I'm becoming increasingly frustrated at the lack of support for even basic opencypher syntax. I'd appreciate a reply to this issue.
Is there any documentation for what parts of openCypher Agensgraph does/doesn't support? The README and other docs state it supports openCypher but as far as I can see, it doesn't support the following (possibly incomplete) list of features:
CALL
syntax (EXECUTE...INTO...USING
seems similar but not identical and uses different keywords)(a)-[r:TYPE1|TYPE2]->(b)
)Agensgraph seems to implement neither a superset nor a subset of openCypher but more a derivative of it. Is that correct?
