MongoDB Limit

The Limit() Method

To limit the records in MongoDB, you need to use limit() method. limit()method accepts one number type argument, which is the number of documents that you want to display. The limit() function in MongoDB is used to specify the maximum number of results to be returned. Only one parameter is required for this function.to return the number of the desired result. Sometimes it is required to return a certain number of results after a certain number of documents. The skip() can do this job.

Syntax:

Basic syntax of limit() method is as follows

>db.COLLECTION_NAME.find().limit(NUMBER)

Example

Consider the collection myycol has the following data

{ "_id" : ObjectId(5983548781331adf45ec5), "title":"MongoDB Overview"}
{ "_id" : ObjectId(5983548781331adf45ec6), "title":"NoSQL Overview"}
{ "_id" : ObjectId(5983548781331adf45ec7), "title":"Tutorials Point Overview"}

Following example will display only 2 documents while quering the document.

>db.mycol.find({},{"title":1,_id:0}).limit(2)
{"title":"MongoDB Overview"}
{"title":"NoSQL Overview"}
>

If you don't specify the number argument in the limit() method then it will display all documents from the collection.
