在 Cypher 查询中结束 UNWIND 语句 [英] End UNWIND statement in a Cypher Query

问题描述

如果我有一个展开参数的密码查询，那么查询的该部分之后的所有内容都被称为展开的 x 次.我想想办法结束放松并继续做其他事情.

If I have a cypher query that unwinds a parameter, everything after that portion of the query is called x number of times of the unwind. I'd like to figure out a way to end the unwind and continue with other things.

MATCH (thing:Thing)
UNWIND { names } AS name
CREATE thing-[:HAS_NAME]-(n:Name {name: name})
//done with the unwind
WITH (thing)
CREATE thing[:HAS_AGE]-(a:Age {age: 20})

在上面的例子中，由于展开，我最终会得到两个东西-[:HAS_AGE]->() 关系.我是否必须将其拆分为单独的语句?

In the above example, I will end up with two thing-[:HAS_AGE]->() relationships because of the unwind. Do I have to split this into separate statements?

推荐答案

展开后你有两行.如果您在继续之前重新折叠 thing，那么您将再次拥有一个.

After the unwind you have two rows. If you re-collapse thing before moving on you will then have a single again.

MATCH (thing:Thing)
UNWIND { names } AS name
CREATE thing-[:HAS_NAME]-(n:Name {name: name})
//done with the unwind
WITH distinct thing
CREATE thing[:HAS_AGE]-(a:Age {age: 20})
