MySQL Insert

In this article, we will dive deep into the topic of Python MySQL insertions, covering everything from the basics to advanced techniques. By the end of this article, you will have a comprehensive understanding of how to use Python to insert data into a MySQL database.

Introduction

Python and MySQL are two of the most popular tools used in the tech industry. Python is a high-level programming language that is easy to learn and has a vast library of modules. On the other hand, MySQL is a widely-used relational database management system that is used to store and manage data.

Inserting data into a MySQL database using Python is a fundamental task that any programmer must learn. In this article, we will go through the steps to insert data into a MySQL database using Python, and we will also cover some best practices to ensure that your code is efficient and scalable.

Setting Up

Before we dive into the code, we need to make sure that we have the necessary tools installed. We will need to install the following packages:

• Python
• MySQL Connector/Python

Once you have installed these packages, we can move on to the next step, which is establishing a connection to the MySQL database.

Establishing a Connection to the MySQL Database

In order to insert data into a MySQL database using Python, we first need to establish a connection to the database. We can do this by using the MySQL Connector/Python module.

To establish a connection, we need to provide the following information:

• Host name
• User name
• Password
• Database name

Once we have established a connection, we can then create a cursor object to execute SQL statements.

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  password="yourpassword",
  database="mydatabase"
)

mycursor = mydb.cursor()

Inserting Data

Now that we have established a connection to the database, we can move on to inserting data into the database. There are two ways to insert data into a MySQL database using Python:

1. Inserting a Single Row
2. Inserting Multiple Rows

Inserting a Single Row

To insert a single row into a MySQL database, we can use the INSERT INTO statement.

sql = "INSERT INTO customers (name, address) VALUES (%s, %s)"
val = ("John", "Highway 21")

mycursor.execute(sql, val)

mydb.commit()

print(mycursor.rowcount, "record inserted.")

Inserting Multiple Rows

To insert multiple rows into a MySQL database, we can use the executemany() method.

sql = "INSERT INTO customers (name, address) VALUES (%s, %s)"
val = [
  ('Peter', 'Lowstreet 4'),
  ('Amy', 'Apple st 652'),
  ('Hannah', 'Mountain 21'),
  ('Michael', 'Valley 345'),
  ('Sandy', 'Ocean blvd 2'),
  ('Betty', 'Green Grass 1'),
  ('Richard', 'Sky st 331'),
  ('Susan', 'One way 98'),
  ('Vicky', 'Yellow Garden 2'),
  ('Ben', 'Park Lane 38'),
  ('William', 'Central st 954'),
  ('Chuck', 'Main Road 989'),
  ('Viola', 'Sideway 1633')
]

mycursor.executemany(sql, val)

mydb.commit()

print(mycursor.rowcount, "records inserted.")

Conclusion

In this article, we have covered the basics of inserting data into a MySQL database using Python. We have discussed how to establish a connection to the database and how to use the INSERT INTO statement to insert data. We have also covered how to insert multiple rows using the executemany() method.

By following the techniques discussed in this article, you can insert data into a MySQL database using Python with ease. This will allow you to store and manage data in an efficient and scalable way.
