Question

我对MongoChef中的以下查询没有任何乐趣 - 它不返回任何结果。如果我在mLab中运行相同的查询，那么它可以工作。我想知道它可能出现什么问题。

$match : {
"account_balances_date": {
    "$gte": {
        "$date": "2016-04-01T00:00:00.000Z"
    },
    "$lte": {
        "$date": "2016-08-01T00:00:00.000Z"
    }
}
}

这是一个示例文档，其中account_balances_date位于查询范围内。感谢

如[{3}}所述，运算符$date将JSON格式扩展为存储date对象。运行查询时，可能无法在所有GUI工具中识别它。相反，您可能希望改为使用ISODate("2016-04-01T00:00:00.000Z")：

$match: {
    "account_balances_date": {
        "$gte": ISODate("2016-04-01T00:00:00.000Z"),
        "$lte": ISODate("2016-08-01T00:00:00.000Z")
    }
}

Mongodb日期范围查询不返回任何结果
