Hello and welcome back to my new blog. In this blog, I am going to share with you the code of the video insert, update, delete, and retrieve so to access the code please do read the full blog.
Insert Code with Explanation in Detail👇
In this Python MongoDB tutorial, you'll learn how to use the PyMongo library to connect to a MongoDB database and insert employee data into it. We'll walk you through the process step by step, explaining each part of the code along the way.
from pymongo import MongoClient
# Connect to the MongoDB server running on localhost at port 27017
Client = MongoClient("localhost:27017")
# Access the 'EmployeeData' database
db = Client.EmployeeData
# Define a function to insert employee data into the 'Employees' collection
def insert():
try:
# Prompt the user for employee details
employeeID = input("Enter employee id: ")
employeeName = input("Enter name: ")
employeeAge = input("Enter age: ")
employeeCountry = input("Enter country: ")
# Insert the employee data into the 'Employees' collection
db.Employees.insert_one(
{
"id": employeeID,
"name": employeeName,
"age": employeeAge,
"country": employeeCountry
})
print("\nInserted successfully\n")
except Exception as e:
print(str(e))
# Call the insert function to insert employee data
insert()
Update Code with Explanation in Detail👇
In this Python MongoDB tutorial, we'll guide you through the process of updating employee data in a MongoDB database using the PyMongo library. Watch this video to learn how to connect to your MongoDB server, access a specific database, and update employee records with ease.
from pymongo import MongoClient
# Connect to the MongoDB server running on localhost at port 27017
Client = MongoClient("localhost:27017")
# Access the 'EmployeeData' database
db = Client.EmployeeData
# Define a function to update employee data in the 'Employees' collection
def update():
try:
# Prompt the user for the employee name and new age
name = input("Enter employee name that you want to update: ")
age = input("Enter employee age that you want to update: ")
# Use the update_many method to update matching records
db.Employees.update_many({"name": name}, {"$set": {"age": age}})
print("Updated successfully")
except Exception as e:
print(str(e))
# Call the update function to update employee data
update()
Delete Code with Explanation in Detail👇
In this Python MongoDB tutorial, we'll show you how to use the PyMongo library to connect to a MongoDB database and delete employee data from it. Join us as we guide you through the process step by step, making it easy for you to manage your MongoDB collections.
from pymongo import MongoClient
# Connect to the MongoDB server running on localhost at port 27017
Client = MongoClient("localhost:27017")
# Access the 'EmployeeData' database
db = Client.EmployeeData
# Define a function to delete employee data from the 'Employees' collection
def delete():
try:
# Prompt the user for the employee name to be deleted
criteria = input("Enter name that you want to delete from the database: ")
# Use the delete_many method to remove matching records
db.Employees.delete_many({"name": criteria})
print("Deleted successfully")
except Exception as e:
print(str(e))
# Call the delete function to remove employee data
delete()
Retrieve Code with Explanation in Detail👇
In this Python MongoDB tutorial, we'll explore how to use the PyMongo library to connect to a MongoDB database and retrieve employee data from it. Join us as we walk you through the code step by step, demonstrating how to access and display data stored in your MongoDB collections
from pymongo import MongoClient
# Connect to the MongoDB server running on localhost at port 27017
Client = MongoClient("localhost:27017")
# Access the 'EmployeeData' database
db = Client.EmployeeData
# Retrieve all data from the 'Employees' collection
empcol = db.Employees.find()
# Display all employee data from the database
print("All data from the database:")
for emp in empcol:
print(emp)
