1. Objective

We have learned how to insert and query a document in a collection in MongoDB. In this MongoDB Tutorial, we are going to see what is MongoDB limit and how to limit record in MongoDB. Moreover, we will discuss MongoDB Skip() Method with example. At last, we discuss some MongoDB Limit examples.

So, let’s start with MongoDB Limit Records.

2. MongoDB Limit Records

When we query a collection, it shows all the documents contained in it. The limit cursor is used for retrieving only numbers of documents that we need. We can use MongoDB limit() method to specify the number of documents we want it to return.

When we query a document using the db.collection_name.find() method, we can append this method to specify the limit.

Let’s understand this with an example.

First, run a query without specifying the limit.

3. MongoDB Skip() Method

When we use the MongoDB limit() method, it shows from the beginning of the collection to the specified limit. If we want it to start not from the beginning and skipping some documents, we can use the Skip() method for this task.

To do this, we need to add the skip() in the cursor and specify the number of documents that we want to skip.

Let’s query the same collection after adding MongoDb skip().

This shows that MongoDB skip can be used with any query without using MongoDB limit.

So, this was all about MongoDB Limit Tutorial. Hope you like our explanation.

4. Conclusion

Hence, we saw that how limiting helps us to see the documents easy. MongoDB Limit is a very useful function. We can use MongoDB limit when the number of documents is so many. This will help us to search the specific documents easily. In conclusion, we discuss MongoDB Skip Method. In the fore coming articles, we will discuss indexing and advanced indexing and it’s limitation. Furthermore, if you have any query, feel free to ask in a comment section.
