I am participating in a course by the University of MongoDB. When I input the command as above into mongo shell, an Error occurs: TypeError: Property 'insertMany' of object test.col is not a function how to solve it? I have read the docs but still failed.

db.col.insertMany(

I had a similar problem. You need to have version 3.2

> New in version 3.2.

You need to update your version of mongodb to use insertMany.

It's not so hard. I did it a couple weeks ago to use insertMany

I am newbie in MongoDB , I got similar error in another scenario. I am adding that also an answer here, any future reader may find useful!

db.users.insertMany ([{name:"Ajith",status:"pending",age:25}, {name:"Kumar",status:"withheld",age:40}, {name:"Lal",status:"passed",age:34}, {name:"Tishil Joppen",status:"high",age:28}])

I forgot to include the square brackets , and got the same error!!

since your Mongo version is MongoDB: db version v2.6.12 (< 3.2) you need to run

db.col.insert(
[
    {
    "_id" : "tt0084726",
    "title" : "Star Trek II: The Wrath of Khan",
    "year" : 1982,
    "type" : "movie"
    },
    {
    "_id" : "tt0796366",
    "title" : "Star Trek",
    "year" : 2009,
    "type" : "movie"
    },
    {
    "_id" : "tt0084726",
    "title" : "Star Trek II: The Wrath of Khan",
    "year" : 1982,
    "type" : "movie"
    }
]);

Ensure your table name is plural:

db.cols.insertMany
