以下查詢有什麼問題？ [Neo4j的1.8.2，嵌入式]Cypher：ThisShouldNotHappenError：此執行計劃不應存在
start merchant = node:merchants('id:10')
match (merchant)<-[:VALID_AT]-(offer)-[:TARGET_PINCODE]->(pincode)<-[:RESIDES_IN]-(customer) where (offer)-[:VALID_OFFER]->() and offer.endDate > 1
return count(offer)
網站管理返回undefined

注意：提供回報，而不是返回計數（報價）的作品
我希望我能夠更多地讚揚這個 – Tyrsius 2013-04-22 20:21:52
99％肯定這固定在1.9。 :( – 2013-04-22 22:08:21
