Delete Multiple Documents
You can delete multiple documents in a collection at once using the
collection.deleteMany() method.
Pass a query document to the deleteMany() method to specify a subset
of documents in the collection to delete. If you do not provide a query
document (or if you provide an empty document), MongoDB matches all documents
in the collection and deletes them. While you can use deleteMany()
to delete all documents in a collection, consider using
drop() instead for better performance
and clearer code.
You can specify more options in the options object passed in
the second parameter of the deleteMany() method. For more detailed
information, see the
deleteMany() API documentation.
Example
The following snippet deletes multiple documents from the movies
collection. It uses a query document that configures the query to
match and delete movies with the title "Santa Claus".
Note
You can use this example to connect to an instance of MongoDB and interact with a database that contains sample data. To learn more about connecting to your MongoDB instance and loading a sample dataset, see the Usage Examples guide.
Running the preceding example for the first time, you see the following output:
Deleted 19 documents
If you run the example more than once, you see the following output because you deleted the matching documents in the first run:
Deleted 0 documents
