MANDATORY MATCH

[jacobfriedman]

Taking this from examples:

MANDATORY MATCH (u:User {id: $user})
MANDATORY MATCH (c:City {name: $city})
MANDATORY MATCH (old:Product {id: $product})<-[:BOUGHT]-(u)
MATCH (store)-[:IN]->(c),
   (store)-[:SELLS]->(new:Product),
   (new)-[:MADE_BY]->(brand)<-[:MADE_BY]-(old)
WHERE new.availability > 0 AND new.category = old.category
RETURN store, count(DISTINCT new) AS offers
ORDER BY offers

See here

I can't find any rules in the EBNF for MANDATORY MATCH, even though MANDATORY is a reserved word. Please advise...

Hi Jacob

Thank you for raising this issue.

Although MANDATORY MATCH was accepted into Cypher, it is not at this current time included in the TCK and grammar.

I have added a note to this effect at the top of the article -- apologies for the confusion.

Thanks Petra — On that note; is there anything else that could be missing?
