加载 RedisGraph 后，您可以使用 redis-cli 与之交互。

在这里，我们将快速创建一个小图表，表示摩托车骑手和车队的子集 参加 MotoGP 联赛。创建后，我们将开始查询数据。

跟redis-cli

连接到 redis。

$ redis-cli -p 12543
127.0.0.1:12543>

Run these commands:

127.0.0.1:12543> GRAPH.QUERY MotoGP "CREATE (:Rider {name:'Valentino Rossi'})-[:rides]->(:Team {name:'Yamaha'}), (:Rider {name:'Dani Pedrosa'})-[:rides]->(:Team {name:'Honda'}), (:Rider {name:'Andrea Dovizioso'})-[:rides]->(:Team {name:'Ducati'})"
1) (empty list or set)
2) 1) Labels added: 2
   2) Nodes created: 6
   3) Properties set: 6
   4) Relationships created: 3
   5) "Query internal execution time: 0.399000 milliseconds"

Now that our MotoGP graph is created, we can start asking questions. For example: Who's riding for team Yamaha?

127.0.0.1:12543> GRAPH.QUERY MotoGP "MATCH (r:Rider)-[:rides]->(t:Team) WHERE t.name = 'Yamaha' RETURN r,t"
1) 1) 1) "r.name"
      2) "t.name"
   2) 1) "Valentino Rossi"
      2) "Yamaha"
2) 1) "Query internal execution time: 0.122000 milliseconds"

How many riders represent team Ducati?

127.0.0.1:12543> GRAPH.QUERY MotoGP "MATCH (r:Rider)-[:rides]->(t:Team {name:'Ducati'}) RETURN count(r)"
1) 1) 1) "count(r)"
   2) 1) "1.000000"
2) 1) "Query internal execution time: 0.129000 milliseconds"
