Neo4j Cypher布爾條件和IN

Question

在繼續我的上一個問題Neo4j Cypher查詢為null或IN時，我已將isPublic屬性添加到Tenant節點。

現在我需要延長善意所創建的查詢frant.hartm與額外的檢查parentD和childD租戶isPublic條件。

我的發言擴展到以下內容：

t.isPublic OR t in tenants WHERE (parentD)-[:BELONGS_TO]-(t)

但失敗，但以下異常：

org.neo4j.ogm.exception.CypherException: Error executing Cypher; Code: Neo.ClientError.Statement.SyntaxError; Description: Invalid input 'W': expected whitespace, comment, '{', node labels, MapLiteral, a parameter, a relationship pattern, '(', '.', '[', "=~", IN, STARTS, ENDS, CONTAINS, IS, '^', '*', '/', '%', '+', '-', '=', "<>", "!=", '<', '>', "<=", ">=", AND, XOR, OR, ',' or ')' (line 1, column 254 (offset: 253))
"MATCH (t:Tenant) WHERE ID(t) in {tenantIds} WITH COLLECT(t) as tenants MATCH (parentD)-[:CONTAINS]->(childD:Decision)-[ru:CREATED_BY]->(u:User) WHERE id(parentD) = {decisionId} AND (not(parentD)-[:BELONGS_TO]-(:Tenant) OR any(t.isPublic OR t in tenants WHERE (parentD)-[:BELONGS_TO]-(t))) AND (not (childD)-[:BELONGS_TO]-(:Tenant) OR any(t.isPublic OR t in tenants WHERE (childD)-[:BELONGS_TO]-(t)))  RETURN ru, u, childD ORDER BY childD.createDate ASC SKIP 0 LIMIT 100"
                                                                                                                                                                                                                                                              ^

現在的完整查詢如下所示：

MATCH (t:Tenant) WHERE ID(t) in {tenantIds} 
WITH COLLECT(t) as tenants 
MATCH (parentD)-[:CONTAINS]->(childD:Decision)-[ru:CREATED_BY]->(u:User) 
WHERE 
id(parentD) = {decisionId} 
AND
 (not(parentD)-[:BELONGS_TO]-(:Tenant) OR any(t.isPublic OR t in tenants WHERE (parentD)-[:BELONGS_TO]-(t))) 
AND
 (not (childD)-[:BELONGS_TO]-(:Tenant) OR any(t.isPublic OR t in tenants WHERE (childD)-[:BELONGS_TO]-(t)))  
RETURN ru, u, childD 
ORDER BY childD.createDate ASC 
SKIP 0 LIMIT 100

如何修復此查詢以支持t.isPublic ？

Answer 1

任何運算符的語法如下：

any(variable IN list WHERE predicate)

參見： https : //neo4j.com/docs/developer-manual/current/cypher/functions/predicates/#functions-any

您將t.isPublic放到錯誤的位置，在該上下文中未定義t，需要將其放在內部WHERE子句之后：

any(t in tenants WHERE t.isPublic OR (parentD)-[:BELONGS_TO]-(t))
