Question

我是MongoDB的新手。我试图更新MongoDB中的许多记录。但它把这个错误扔给了我。任何人都可以帮助离开这里吗？

2017-04-13T11：23：07.572-0700 E QUERY [thread1]错误：更新操作文档必须包含原子操作符： DBCollection.prototype.updateMany@src/mongo/shell/crud_api.js：568：1 @（壳）：1：1

示例数据：

function back()
{
    var i = 0;
    var jsArray = @Html.Raw(Json.Serialize(Model));
    console.log(jsArray[i].Id;)

}

示例查询：

{
    userId: "id#1",
    username: "abc",
    firstName: "ABC",
    lastName: "DEF",
    age: 19
}
{
    userId: "id#1",
    username: "abc",
    firstName: "ABC",
    lastName: "DEF",
    age: 19
}
{
    userId: "id#1",
    username: "abc",
    firstName: "ABC",
    lastName: "DEF",
    age: 19
}
{
    userId: "id#1",
    username: "abc",
    firstName: "ABC",
    lastName: "DEF",
    age: 19
}

Answer 1

updateMany要求您指定要应用的操作。您的示例查询将如下所示：

db.users.updateMany(
{
    userId: {
        $in: ["id#1","id#2","id#3"]
    }
},
{
  $set: {
    userId: "id#12345",
    username: "abc",
    firstName: "ABC",
    lastName: "DEF",
    age: 19
  }
})

MongoDB 3.2.6无法运行updateMany（）
