Creating a database in MySQL using python

After establishing connection with MySQL, to manipulate data in it you need to connect to a database. You can connect to an existing database or, create your own.

You would need special privileges to create or to delete a MySQL database. So if you have access to the root user, you can create any database.

Example - Creating a Database

Following example establishes connection with MYSQL and creates a database in it.

main.py

import mysql.connector

#establishing the connection
conn = mysql.connector.connect(user='root', password='password', host='127.0.0.1')

#Creating a cursor object using the cursor() method
cursor = conn.cursor()

#Dropping database MYDATABASE if already exists.
cursor.execute("DROP database IF EXISTS MyDatabase")

#Preparing query to create a database
sql = "CREATE database MYDATABASE";

#Creating a database
cursor.execute(sql)

#Retrieving the list of databases
print("List of databases: ")
cursor.execute("SHOW DATABASES")
print(cursor.fetchall())

#Closing the connection
conn.close()

Output

List of databases:
[('details',), ('information_schema',), ('jpadb',), ('mydatabase',), ('mydb',), ('mysql',), ('performance_schema',), ('sys',), ('test',), ('tutorials',), ('tutorialspoint',)]
