我有以下查询
MATCH (category:Category {id:'qwe'} )
MATCH (category)-[:CHILD_OF*0..50]->(subcats:Category)<-[:PHOTO_OF]-(photo:Photo)
return (subcats.name), count(photo)
此查询仅返回照片所属的确切类别的照片计数,我想要分类照片的聚合计数,包括子类别的照片,我想这曾经工作但在2.3.x更新后损坏。
答案 0 :(得分:0)
尝试此查询:
MATCH (category:Category {id:'qwe'} )
MATCH (category)-[:CHILD_OF*0..50]->(subcats:Category)<-[:PHOTO_OF]-(photo:Photo)
WITH category.name AS cat, collect(subcats.name) AS subcats, count(photo) AS num
RETURN cat, subcats, num
这是你想要实现的行为吗?
我不确定您的查询在2.2.x和2.3之间可能发生了什么变化。您愿意分享您的数据,以便我们可以尝试重现吗?
