在Actor / Movie演示图上,cypher在单独的数组中返回列名。
MATCH (n:Person) RETURN n.name as Name, n.born as Born ORDER BY n.born LIMIT 5
结果:
{ "columns" : [ "Name", "Born" ], "data" : [ [ "Max von Sydow", 1929 ], [ "Gene Hackman", 1930 ], [ "Richard Harris", 1930 ], [ "Clint Eastwood", 1930 ], [ "Mike Nichols", 1931 ] ]}
是否可以改为标记每个节点属性?
{ "nodes" : [ ["Name": "Max von Sydow", "Born": 1929 ], ...] }
如果我返回节点而不是选定的属性,我会得到太多属性。
MATCH (n:Person) RETURN n LIMIT 5
结果:
{ "columns" : [ "n" ], "data" : [ [ { "outgoing_relationships" : "http://localhost:7474/db/data/node/58/relationships/out", "labels" : "http://localhost:7474/db/data/node/58/labels", "data" : { "born" : 1929, "name" : "Max von Sydow" }, "all_typed_relationships" : "http://localhost:7474/db/data/node/58/relationships/all/{-list|&|types}", "traverse" : "http://localhost:7474/db/data/node/58/traverse/{returnType}", "self" : "http://localhost:7474/db/data/node/58", "property" : "http://localhost:7474/db/data/node/58/properties/{key}", "outgoing_typed_relationships" : "http://localhost:7474/db/data/node/58/relationships/out/{-list|&|types}", "properties" : "http://localhost:7474/db/data/node/58/properties", "incoming_relationships" : "http://localhost:7474/db/data/node/58/relationships/in", "extensions" : { }, "create_relationship" : "http://localhost:7474/db/data/node/58/relationships", "paged_traverse" : "http://localhost:7474/db/data/node/58/paged/traverse/{returnType}{?pageSize,leaseTime}", "all_relationships" : "http://localhost:7474/db/data/node/58/relationships/all", "incoming_typed_relationships" : "http://localhost:7474/db/data/node/58/relationships/in/{-list|&|types}" } ], ... ]}

您可以在Neo4j 2.0中使用新的文字地图语法,并执行以下操作:
MATCH (n:Person)
RETURN { Name: n.name , Born: n.born } as Person
ORDER BY n.born
LIMIT 5
