19-May-2023A cursor is a pointer to a set of results returned by a query in MongoDB. A result set is the actual data returned by the query.
When you execute a query in MongoDB, the database returns a cursor. The cursor is a pointer to the data returned by the query. You can use the cursor to iterate through the data one row at a time.
The result set is the actual data returned by the query. The result set is a collection of rows, where each row is a document. A document is a JSON-like object that contains data.
The difference between a cursor and a result set is that a cursor is a pointer to the data, while a result set is the actual data.
Here is an example of how to use a cursor to iterate through the results of a query:
Code snippet
In this example, we create a cursor and then iterate through it one row at a time. We get the next document from the cursor and then do something with it.
