MongoDB limit() Method

In MongoDB, limit() method is used to limit the fields of document that you want to show. Sometimes, you have a lot of fields in collection of your database and have to retrieve only 1 or 2. In such case, limit() method is used.

The MongoDB limit() method is used with find() method.

Scenario:

Consider an example which has a collection name javatpoint.

This collection has following fields within it.

Here, you have to display only one field by using limit() method.

Example

After the execution, you will get the following result

Output:

{ "_id" : ObjectId("564dbced8e2c097d15fbb601"), "Course" : "Java", "details" : {
 "Duration" : "6 months", "Trainer" : "Sonoo Jaiswal" }, "Batch" : [ { "size" :
"Medium", "qty" : 25 } ], "category" : "Programming Language" } 

MongoDB skip() method

In MongoDB, skip() method is used to skip the document. It is used with find() and limit() methods.

Syntax

Scenario:

Consider here also the above discussed example. The collection javatpoint has three documents.

Execute the following query to retrieve only one document and skip 2 documents.

Example

After the execution, you will get the following result

Output:

{ "_id" : ObjectId("564dbced8e2c097d15fbb603"), "Course" : "Web Designing", "det
ails" : { "Duration" : "3 months", "Trainer" : "Rashmi Desai" }, "Batch" : [ { "
size" : "Small", "qty" : 5 }, { "size" : "Large", "qty" : 10 } ], "category" : "
