python-mysqlHow can I use Python to update multiple rows in a MySQL database?

Using Python to update multiple rows in a MySQL database is very easy. First, you need to import the necessary modules, such as MySQLdb and sys.

import MySQLdb
import sys

Then, you need to connect to the database and create a cursor object.

db = MySQLdb.connect(host="localhost", user="user", passwd="pass", db="database")
cursor = db.cursor()

Next, you need to create an SQL query that will update the data in the database.

sql = "UPDATE table SET field1 = %s, field2 = %s WHERE condition"

Finally, you need to execute the query.

try:
   # Execute the SQL command
   cursor.execute(sql, (value1, value2))
   # Commit your changes in the database
   db.commit()
except:
   # Rollback in case there is any error
   db.rollback()

Once the query has been executed, you can close the database connection.

db.close()
