Python Mongodb – Delete_many()
MongoDB is a general-purpose, document-based, distributed database built for modern application developers and the cloud. It is a document database, which means it stores data in JSON-like documents. This is an efficient way to think about data and is more expressive and powerful than the traditional table model.
Delete_many()
Delete_many() is used when one needs to delete more than one document. A query object containing which document to be deleted is created and is passed as the first parameter to the delete_many().
Sample Database:
Example 1: Deleting all the documents where the name starts with ‘A’.
import pymongo # Connecting to the databasemydb = client["GFG"] # Connecting the to collectioncol = mydb["Geeks"] query = {"Name": {"$regex": "^A"}}d = col.delete_many(query) print(d.deleted_count, " documents deleted !!") |
Output:
2 documents deleted !!
MongoDB Shell:
Example 2:
import pymongo # Connecting to the databasemydb = client["GFG"] # Connecting the to collectioncol = mydb["Geeks"] query = {"Class": '3'}d = col.delete_many(query) print(d.deleted_count, " documents deleted !!") |
Output:
1 documents deleted !!
