Update Multiple Documents
Note
If you specify a callback method, updateMany() returns nothing. If you
do not specify one, this method returns a Promise that resolves to the
result object when it completes. See our guide on Promises and
Callbacks for more information, or see the
API documentation for
information on the result object.
You can update multiple documents using the
collection.updateMany() method.
The updateMany() method accepts a filter document and an update document. If the query matches documents in the
collection, the method applies the updates from the update document to fields
and values of the matching documents. The update document requires an update operator to modify a field in a document.
You can specify additional options in the options object passed in
the third parameter of the updateMany() method. For more detailed
information, see
the updateMany() API documentation.
