Cypher:在WHERE in中传递多个参数

Question

如何为WHERE条件传递参数？

事实上，这很好：

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

但是，如何传递多个guid作为此查询的参数：

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

我使用neo4jphp客户端，我的代码如下：

$client = new EverymanNeo4jClient( "neo4j server address", "7474" );
$result = new EverymanNeo4jCypherQuery( $client, "match (b:Book) where b.guid={guid} return b", array('guid'=>$guid1) );
$res = $result->getResultSet();

Answer 1

您应该传递一个数组作为参数，查询如下所示：

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

$client = new EverymanNeo4jClient( "neo4j server address", "7474" );
$result = new EverymanNeo4jCypherQuery( $client, "match (b:Book) where b.guid in {MyMap} return b", array('myMap'=> array($guid1, $guid2, $guid3)) );
$res = $result->getResultSet();
