azure - 如何在 MS Azure CosmosDB 中使用 SQL 查询嵌套列表和数组？

Question

我有以下(Azure)CosmosDB(子)结构，它有 2 个嵌套数组:

{
    "id": "documentTypes",
    "SomeThing": "SomeThing",
    "configuration": [
        {
            "language": "en",
            "list": [
                {
                    "id": 1,
                    "name": "Supporting Documents"
                },
                {
                    "id": 2,
                    "name": "Summary PDF"
                },
            ]
        }
    ],
}

我尝试了以下查询，但结果不佳。

SELECT * FROM c WHERE c.documentTypes.configuration[0].list[0].id FROM c

和

SELECT
    p.id,       
    p.name
FROM f
    JOIN c IN f.configuration
    JOIN p IN c.list
WHERE c.id == 'documentTypes'

Q:如何才能只获取name和id的列表？

Answer 1

你需要这个吗？

SELECT ARRAY(SELECT VALUE e FROM c JOIN d IN c["configuration"] JOIN e IN d["list"]) AS Result FROM c

输出:

[ { "Result": [ { "id": 1, "name": "Supporting Documents" }, { "id": 2, "name": "Summary PDF" } ] } ]
