In this article, we are going to see how we can rename or alter the name of a column table using Python. Python allows the integration of a wide range of database servers with applications. A database interface is required to access a database from Python. MySQL Connector-Python module is an API in python for communicating with a MySQL database.
Approach:
- Import module.
- Make a connection request with the database.
- Create an object for the database cursor.
- Execute the following MySQL query:
ALTER TABLE your_table_name RENAME COLUMN original_column_name TO new_column_name;
Example:
In this example we are using this database table with the following query;
Below is the implementation:
Python3
# Establish connection to MySQL database import mysql.connector db = mysql.connector.connect( host="localhost", user="root", password="root123", database = "Lazyroar" ) #getting the cursor by cursor() method mycursor = db.cursor() query = "ALTER TABLE persons RENAME COLUMN PersonID TO Emp_Id;"mycursor.execute(query) # close the Connection db.close() |
After running this script, let’s check our tables:
