Untuk membatasi hasil di MongoDB, kita dapat menggunakan metode limit().
Metode limit() mengambil satu parameter, angka yang menentukan berapa banyak dokumen yang akan dikembalikan.
Anggap saja kita memiliki koleksi “customers”:
| {‘_id’: 1, ‘name’: ‘John’, ‘address’: ‘Highway37’} {‘_id’: 2, ‘name’: ‘Peter’, ‘address’: ‘Lowstreet 27’} {‘_id’: 3, ‘name’: ‘Amy’, ‘address’: ‘Apple st 652’} {‘_id’: 4, ‘name’: ‘Hannah’, ‘address’: ‘Mountain 21’} {‘_id’: 5, ‘name’: ‘Michael’, ‘address’: ‘Valley 345’} {‘_id’: 6, ‘name’: ‘Sandy’, ‘address’: ‘Ocean blvd 2’} {‘_id’: 7, ‘name’: ‘Betty’, ‘address’: ‘Green Grass 1’} {‘_id’: 8, ‘name’: ‘Richard’, ‘address’: ‘Sky st 331’} {‘_id’: 9, ‘name’: ‘Susan’, ‘address’: ‘One way 98’} {‘_id’: 10, ‘name’: ‘Vicky’, ‘address’: ‘Yellow Garden 2’} {‘_id’: 11, ‘name’: ‘Ben’, ‘address’: ‘Park Lane 38’} {‘_id’: 12, ‘name’: ‘William’, ‘address’: ‘Central st 954’} {‘_id’: 13, ‘name’: ‘Chuck’, ‘address’: ‘Main Road 989’} {‘_id’: 14, ‘name’: ‘Viola’, ‘address’: ‘Sideway 1633’} |
Contoh:
Batasi hasil hanya untuk mengembalikan 5 dokumen
import pymongo
myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]
myresult = mycol.find().limit(5)
#print the result:
for x in myresult:
print(x)
