CosmosDB UDF 到 return 5 天后的日期

Question

我正在尝试编写一个小的 UDF 用于测试目的，它将 return 今天的日期加上 5 天，我需要这个来测试一个比较日期范围的小查询以确保文档应该被收录

文档看起来像这样

{
    "id": "12345",
    "brand": "XXX",
    "PromotionName": "Test Promo 1",
    "PromotionType": "Deal",
    "PromotionSticker": "Sticker 1",
    "StartDate": "2020-05-15T00:00:00.1212122Z",
    "EndDate": "2020-05-30T00:00:00.1212122Z",
    "Variants": [
        "0628462008001",
        "0628462008002",
        "0644324003002"
    ],
    "Stores": [
        "SE0623"
    ],
    "Users": [
        "ALL"
    ],
    "DiscountInPercent": "30",
    "RedPriceStores": null,
    "CreatedDate": "20200515",
    "CreatedBy": "SLAPI Promotions API ClientId: 123",
    "UpdatedDate": null,
    "UpdatedBy": null,
    "Consumer": "Storelens_V2",
    "_rid": "HwVmAIFaOoEBAAAAAAAAAA==",
    "_self": "dbs/HwVmAA==/colls/HwVmAIFaOoE=/docs/HwVmAIFaOoEBAAAAAAAAAA==/",
    "_etag": "\"1100092f-0000-0c00-0000-5ebe07280000\"",
    "_attachments": "attachments/",
    "_ts": 1589511976
}

所以我写了一个像这样的小查询

SELECT * 
FROM c
WHERE ARRAYCONTAINS(c.Variants, '0628462008001')
AND ARRAYCONTAINS(c.Stores, 'SE0623')
AND c.StartDate <= (SELECT GetCurrentDateTime())
AND c.EndDate >= (SELECT udf.todaysDatePlus5())

我的想法是我可以使用 UDF 来测试我的查询的有效性，因为它将 return 将来的日期用于测试目的

我的UDF小如下

function todaysDatePlus5(){
    var date = new Date();
    var a = date.setDays(+5);
    return a;
}

但是当我运行这样做时，我收到这样的错误消息

如果我像这样自己尝试 UDF

select udf.todaysDatePlus5()

我收到同样的错误消息

我在这里做错了什么？它是如此简单的 UDF。

Answer 1

尝试如下操作：

function todaysDatePlus5(){
    var date = new Date();
    var a = date.setDate(date.getDate()+5);
    return new Date(a);
}
