Cypher：在 WHERE IN 中传递多个参数

Question

WHERE条件如何传递参数？

确实如此，这很好用：

match (b:Book) where b.guid={guid} return b;

但是，如何将多个 guid 作为此查询的参数传递：

match (b:Book) where b.guid in [guid1,guid2,gid3] return b;

我使用的是neo4jphp客户端，我的代码是这样的：

$client = new Everyman\Neo4j\Client( "neo4j server address", "7474" );
$result = new Everyman\Neo4j\Cypher\Query( $client, "match (b:Book) where b.guid={guid} return b", array('guid'=>$guid1) );
$res = $result->getResultSet();

Answer 1

你应该传递一个数组作为参数，查询应该是这样的：

match (b:Book) where b.guid in {myMap} return b;


$client = new Everyman\Neo4j\Client( "neo4j server address", "7474" );
$result = new Everyman\Neo4j\Cypher\Query( $client, "match (b:Book) where b.guid in {MyMap} return b", array('myMap'=> array($guid1, $guid2, $guid3)) );
$res = $result->getResultSet();
