[Python] MongoDB Delete Document 본문
Delete Document
- 하나의 document를 삭제하려면 delete_one() 메서드를 사용합니다.
- delete_one() 메서드의 첫 번째 매개변수는 삭제할 document를 정의하는 객체입니다.
- query에서 두 개이상의 documents를 찾으면 첫 번째 항목만 삭제됩니다.
# Delete the document with the address "Mountain 21":
myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb['custmers"]
myquery = { "address":"Mountain 21" }
mycol.delete_one(myquery)
Delete Many Documents
- 하나 이상의 문서를 삭제하려면 delete_many() 메서드를 사용하십시오.
- delete_many() 메서드의 첫 번째 매개변수는 삭제할 문서를 정의하는 쿼리 객체입니다.
# Delete all documents were the address start with the letter S:
import pymongo
myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]
myquery = {"address":{"$regex":"^S"} }
x = mycol.delete_many(myquery)
print(x.deleted_count, " docunments deleted.")
Delete All Documents in a Collection
collection의 모든 documents를 삭제하려면 빈 쿼리 객체를 delete_many() 메서드에 전달합니다.
# Delete all documents in the "customers" collection:
import pymongo
myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]
x = mycol.delete_many({})
print(x.deleted_count, " documents deleted.")
