MongoDB 3.2.6无法运行updateMany（）

Question

我是MongoDB的新手。我试图更新MongoDB中的很多记录。但它给我带来了这个错误。任何人都可以帮忙吗？

的样本数据：

{ 
    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",

样品查询：

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

updateMany需要你指定你的操作正在申请。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 
    } 
})
