The examples on this page use the inventory collection. To populate the inventory collection, run the following:

db.inventory.insertMany( [
   { item: "journal", qty: 25, size: { h: 14, w: 21, uom: "cm" }, status: "A" },
   { item: "notebook", qty: 50, size: { h: 8.5, w: 11, uom: "in" }, status: "P" },
   { item: "paper", qty: 100, size: { h: 8.5, w: 11, uom: "in" }, status: "D" },
   { item: "planner", qty: 75, size: { h: 22.85, w: 30, uom: "cm" }, status: "D" },
   { item: "postcard", qty: 45, size: { h: 10, w: 15.25, uom: "cm" }, status: "A" },
]);

You can run the operation in the web shell below:

db.inventory.insert_many([

The delete_many() method returns an instance of pymongo.results.DeleteResult with the status of the operation.

The com.mongodb.client.MongoCollection.deleteMany method returns an instance of com.mongodb.client.result.DeleteResult with the status of the operation.

deleteMany() returns a promise that provides a result. The result.deletedCount property contains the number of documents that matched the filter.

Upon successful execution, the deleteMany() method returns an instance of MongoDB\DeleteResult whose getDeletedCount() method returns the number of documents that matched the filter.

Upon successful execution, the IMongoCollection.DeleteMany() method returns an instance of DeleteResult whose DeletedCount property contains the number of documents that matched the filter.

Delete All Documents that Match a Condition

You can specify criteria, or filters, that identify the documents to delete. The filters use the same syntax as read operations.

To specify equality conditions, use <field>:<value> expressions in the query filter document:

{ <field1>: <value1>, ... }

To specify equality conditions, use <field>:<value> expressions in the query filter document:

{ <field1>: <value1>, ... }

To specify equality conditions, use the com.mongodb.client.model.Filters.eq_ method to create the query filter document:

and(eq( <field1>, <value1>), eq( <field2>, <value2>) ...)

To specify equality conditions, use <field>:<value> expressions in the query filter document:

{ <field1>: <value1>, ... }

To specify equality conditions, use <field> => <value> expressions in the query filter document:

[ <field1> => <value1>, ... ]

To specify equality conditions, construct a filter using the Eq method:

Builders<BsonDocument>.Filter.Eq(<field>, <value>);

To specify equality conditions, use <field> => <value> expressions in the query filter document:

{ <field1> => <value1>, ... }

To specify equality conditions, use <field> => <value> expressions in the query filter document:

{ <field1> => <value1>, ... }

To specify equality conditions, use the com.mongodb.client.model.Filters.eq_ method to create the query filter document:

and(equal(<field1>, <value1>), equal(<field2>, <value2>) ...)

A query filter document can use the query operators to specify conditions in the following form:

{ <field1>: { <operator1>: <value1> }, ... }

A query filter document can use the query operators to specify conditions in the following form:

{ <field1>: { <operator1>: <value1> }, ... }

In addition to the equality condition, MongoDB provides various query operators to specify filter conditions. Use the com.mongodb.client.model.Filters helper methods to facilitate the creation of filter documents. For example:

and(gte(<field1>, <value1>), lt(<field2>, <value2>), eq(<field3>, <value3>))

A query filter document can use the query operators to specify conditions in the following form:

{ <field1>: { <operator1>: <value1> }, ... }

A query filter document can use the query operators to specify conditions in the following form:

[ <field1> => [ <operator1> => <value1> ], ... ]

In addition to the equality filter, MongoDB provides various query operators to specify filter conditions. Use the FilterDefinitionBuilder methods to create a filter document. For example:

var builder = Builders<BsonDocument>.Filter;
builder.And(builder.Eq(<field1>, <value1>), builder.Lt(<field2>, <value2>));

A query filter document can use the query operators to specify conditions in the following form:

{ <field1> => { <operator1> => <value1> }, ... }

A query filter document can use the query operators to specify conditions in the following form:

{ <field1> => { <operator1> => <value1> }, ... }

In addition to the equality condition, MongoDB provides various query operators to specify filter conditions. Use the com.mongodb.client.model.Filters_ helper methods to facilitate the creation of filter documents. For example:

and(gte(<field1>, <value1>), lt(<field2>, <value2>), equal(<field3>, <value3>))

To delete all documents that match a deletion criteria, pass a filter parameter to the deleteMany() method.

To delete all documents that match a deletion criteria, pass a filter parameter to the delete_many() method.

To delete all documents that match a deletion criteria, pass a filter parameter to the com.mongodb.client.MongoCollection.deleteMany method.

To delete all documents that match a deletion criteria, pass a filter parameter to the deleteMany() method.

To delete all documents that match a deletion criteria, pass a filter parameter to the deleteMany() method.

To delete all documents that match a deletion criteria, pass a filter parameter to the IMongoCollection.DeleteMany() method.

To delete all documents that match a deletion criteria, pass a filter parameter to the delete_many() method.

To delete all documents that match a deletion criteria, pass a filter parameter to the delete_many() method.

To delete all documents that match a deletion criteria, pass a filter parameter to the deleteMany() method.

The following example removes all documents from the inventory collection where the status field equals "A":

db.inventory.deleteMany({ status : "A" })
db.inventory.delete_many({"status": "A"})
collection.deleteMany(eq("status", "A"));
db.collection('inventory').deleteMany({ 
  status: "A" 
})
.then(function(result) {
  // process result
})
$deleteResult = $db->inventory->deleteMany(['status' => 'A']);
var filter = Builders<BsonDocument>.Filter.Eq("status", "A");
var result = collection.DeleteMany(filter);
$db->coll("inventory")->delete_many( { status => "A" } );
client[:inventory].delete_many(status: 'A')
collection.deleteMany(equal("status", "A")).execute()

The method returns a document with the status of the operation. For more information and examples, see deleteMany().

The delete_many() method returns an instance of pymongo.results.DeleteResult with the status of the operation.

The com.mongodb.client.MongoCollection.deleteMany method returns an instance of com.mongodb.client.result.DeleteResult with the status of the operation.

deleteMany() returns a promise that provides a result. The result.deletedCount property contains the number of documents that matched the filter.

Upon successful execution, the deleteMany() method returns an instance of MongoDB\DeleteResult whose getDeletedCount() method returns the number of documents that matched the filter.

Upon successful execution, the IMongoCollection.DeleteMany() method returns an instance of DeleteResult whose DeletedCount property contains the number of documents that matched the filter.

Upon successful execution, the delete_many() method returns an instance of MongoDB::DeleteResult whose deleted_count attribute contains the number of documents that matched the filter.

Upon successful execution, the delete_many() method returns an instance of Mongo::Operation::Result, whose deleted_count attribute contains the number of documents that matched the filter.

Upon successful execution, the collection.deleteMany() method returns an Observable with a single element with a DeleteResult type parameter or with an com.mongodb.MongoException.

Remove Only One Document that Matches a Condition

To delete at most a single document that matches a specified filter (even though multiple documents may match the specified filter) use the db.collection.deleteOne() method.

To delete at most a single document that matches a specified filter (even though multiple documents may match the specified filter) use the pymongo.collection.Collection.delete_one() method.

To delete at most a single document that matches a specified filter (even though multiple documents may match the specified filter) use the com.mongodb.client.MongoCollection.deleteOne method.

To delete at most a single document that matches a specified filter (even though multiple documents may match the specified filter) use the Collection.deleteOne() method.

To delete at most a single document that matches a specified filter (even though multiple documents may match the specified filter) use the MongoDB\Collection::deleteOne() method.

To delete at most a single document that matches a specified filter (even though multiple documents may match the specified filter) use the IMongoCollection.DeleteOne()

To delete at most a single document that matches a specified filter (even though multiple documents may match the specified filter) use the MongoDB::Collection::delete_one() method.

To delete at most a single document that matches a specified filter (even though multiple documents may match the specified filter) use the Mongo::Collection#delete_one() method.

To delete at most a single document that matches a specified filter (even though multiple documents may match the specified filter) use the collection.deleteOne() method.

The following example deletes the first document where status is "D".

db.inventory.deleteOne( { status: "D" } )
db.inventory.delete_one({"status": "D"})
collection.deleteOne(eq("status", "D"));
db.collection('inventory').deleteOne({ 
  status: "D" 
})
.then(function(result) {
  // process result
})
$deleteResult = $db->inventory->deleteOne(['status' => 'D']);
var filter = Builders<BsonDocument>.Filter.Eq("status", "D");
var result = collection.DeleteOne(filter);
$db->coll("inventory")->delete_one( { status => "D" } );
client[:inventory].delete_one(status: 'D')
collection.deleteOne(equal("status", "D")).execute()
