Neo4j Query Not Returning Desired Output-CodePudding

Hi I am learning Neo4j Database, I had an issue with one of the query as it seems to be not returning a valid output. Here is my complete dataset

Query that giving issue is MATCH (usr:USER)-[:KNOWS]->(lang:SKILL) where lang.name="Python" AND lang.name="FastAPI" return usr, Expected Output is Vibhav Node. But instead its not returning any value Please help me to understand this. Thanks in Advance!!

CodePudding user response：

You are setting two predicates on the same node, which will not work as a single node cannot have two names. What you need to do is:

MATCH (lang2:SKILL)<-[:KNOWS]-(usr:USER)-[:KNOWS]->(lang:SKILL) 
where lang.name="Python" AND lang2.name="FastAPI" 
return usr
