cypher查询，用于将字符串的键/属性与数组的键/属性连接起来

Question

我正在尝试构建一个cypher查询，我打算将其用作对http请求的json响应。我想在json对象中有两个键：一个是string类型的键/属性，另一个是类型为array的键/属性，如下所示：

> {
>     "id"                                : "9989898676876_all",
>     "inventory"                         : [
>         {
>             "id"                        : "a_aaa",
>             "isFavorite"                : false
>         }, {
>             "id"                        : "b_bbb",
>             "isFavorite"                : false
>         }, {    
>             "id"                        : "c_ccc",
>             "isFavorite"                : false
>         }, {
>             "id"                        : "d_ddd",
>             "isFavorite"                : false
>         }
>     ] }

我尝试使用此密码查询，但却出现错误：

MATCH n 
WHERE n.id='9989898676876'
RETURN n.id + '_all' AS `id`
UNION
MATCH n-[inventory:ALL_]->leaf
WHERE n.id='9989898676876'
RETURN (leaf.id AS `id`, inventory.isFavorite AS `isFavorite`) AS `inventory`

有人可以提供一个cypher响应的小提琴示例，它将字符串的键/属性与数组的键/属性连接起来吗？

通过升序leaf.id订购广告资源，您可以获得结果：

MATCH n-[inventory:ALL_]->leaf
WHERE n.id='9989898676876'
WITH *
ORDER BY leaf.id
RETURN (n.id + '_all') AS id, COLLECT({ id: leaf.id, isFavorite: inventory.isFavorite }) AS inventory;
