Get Rows from Table based on Condition in Python MySQL

Python MySQL – Get rows from Table based on condition

To get rows from MySQL table based on a condition in Python,

1. Create a connection to the MySQL database with user credentials and database name, using connect() function.
2. Get cursor object to the database using cursor() function.
3. Call execute() function on the cursor object, and pass the SELECT FROM table query with WHERE clause.
4. Call fetchall() function on the cursor object. The function returns an iterator to the records in the table. We can use a For loop on this iterator object.

Example

Consider that there is a schema named mydatabase in MySQL. The credentials to access this database are, user: root and password: admin1234, and there is a table named fruits in mydatabase.

In this example, we get the rows from fruits table where country is Mexico.

import mysql.connector

mydb = mysql.connector.connect(
  host="localhost",
  user="root",
  password="admin1234",
  database="mydatabase"
)

mycursor = mydb.cursor()

mycursor.execute("SELECT * FROM fruits WHERE country='Mexico'")

myresult = mycursor.fetchall()

for row in myresult:
  print(row)

Output

('Avocado', 37, 'Mexico')
('Banana', 40, 'Mexico')

Summary

In this tutorial of Python Examples, we learned how to get the records from a table based on a condition in MySQL database, from a Python program.
