mongodb的'updateMany'函数是否已弃用？

Question

db.movieDetails.updateMany({
    "tomato.consensus": null,
    "imdb.votes":{$lt:10000},
    "year":{$gte:2010,$lte:2013}},
    {
       $unset:{"tomato.consensus":""
    }
})

When I typed the command above in the mongo shell, I received an error that stated that updateMany was not a valid function.

TypeError: Property 'updateMany' of object video.movieDetails is not a function at (shell):1:17

I checked the documentation and updateMany is listed a valid function. I would like to know why I received the error.

Answer 1

The updateMany command has not been deprecated. You'll find the documentation for the command here: db.collection.updateMany .

You were unable to use the command because it was introduced in the 3.2 version of MongoDB. You need to install the 3.2 version to use the updateMany command.
