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

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


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()

#Doping 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:
[(''information_schema'',), (''dbbug61332'',), (''details'',), (''exampledatabase'',), (''mydatabase'',), (''mydb'',), (''mysql'',), (''performance_schema'',)]
