Deleting a Document
At some stage you may want to delete a document from a collection. The format is:
db.collection.deleteOne(query_criteria) /* deletes the first document found that matches the query criteria */
db.collection.remove(query_criteria) /* deletes all documents found that matches the query criteria */
Delete Department 40
Department 40 has closed down:
db.deptCollection.deleteOne({"deptno":40})
Note, if the query_criteria only returns one document, remove() and deleteOne() will have the same effect.
