Neo4j密码查询-如何获取特定标签数据？

Question

I want to get only customer and supplier name and ID using cypher query.

"Match (n: customer:supplier) where has (n.ID) return n.ID,n.nme";

How to combine 2 labels to get the data?

Above query is getting syntax error. Please advise.

Answer 1

This for OR label matching:

MATCH (n) 
WHERE (n:customer OR n:supplier) AND exists(n.ID)
RETURN n.ID, n.nme

This for AND label matching:

MATCH (n:customer:supplier) 
WHERE exists(n.ID)
RETURN n.ID, n.nme

Answer 2

The has() function has long since been deprecated and removed. Use exists() instead.

Also I'm not sure what you mean by combine 2 labels to get the data. The query as it is now will only match to nodes with both the :customer and :supplier label. Is that what you want?
