Delete a Column in Table in Python MySQL
Python MySQL - Delete a column in table
To delete a column in MySQL table from a Python program,
- Create a connection to the MySQL database with user credentials and database name, using connect() function.
- Get cursor object to the database using cursor() function.
- Call execute() function on the cursor object, and pass the ALTER table query with the specific column name. The ALTER query removes the specified column in the table.
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 the following program, we remove the country
column in fruits
table using ALTER query.
Python Program
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="root",
password="admin1234",
database="mydatabase"
)
mycursor = mydb.cursor()
try:
mycursor.execute("ALTER TABLE fruits DROP COLUMN country")
print('Column deleted successfully.')
except:
print('An exception occurred during column delete operation.')
mydb.commit()
Output
Column deleted successfully.
Table data after ALTER operation
