Cursor In Mongodb

In this article, we will discuss cursor in MongoDB.

What Is A Cursor?

The cursor is an object returned by the find method.

In this example, we have executed the find method.

The method returns 20 records followed by the message – Type "it" for more.

When you type the word it and press enter, the next 20 records will appear.

You can assign the cursor to the variable and then further iterate through the variable.

The next method is used to retrieve the next document from the result set of a query executed using a cursor.

The hasNext() function is used to check if there are more documents available in the result set of a cursor before retrieving the next document.

To loop through the cursor, use the following command: -

cursor.forEach(doc=>{printjson(doc)})
