Python Interface With MySQL 5

Creating a Database in Python MySQL Connection

Step:1
import required packages

import mysql.connector
from mysql.connector import Error

import mysql.connector
from mysql.connector import Error

Step:2
set up connection

con = mysql.connector.connect
(host=’localhost’,
user=’root’,
password=’ct’)

con = mysql.connector.connect
(host='localhost',
user='root',
password='ct')

Step:3
To check if connection is established or not

if(con.is_connected()==True):
      print(“connected to MYSQL Database”)

if connection is established then message “connected to MYSQL Database” is displayed. Otherwise error message is displayed.

In case of ay error except: part of the program gets executed and error gets displayed.

except Error as e:
       print(e)

if(con.is_connected()==True):
        print("connected to MYSQL Database")

statements
statements

except Error as e:
        print(e)

Step:4
Create a cursor

mycursor=con.cursor()

mycursor=con.cursor()

Step:5
Give SQL command and execute it.

We give SQL command to create DataBase and execute the SQL command using execute function of created cursor.

q1=”create database employee;”
mycursor.execute(q1)
print(“Employee database created”)

q1="create database employee;"
mycursor.execute(q1)
print("Employee database created")

Step:4
Finally the database connection is closed.

finally:
        if con is not None and con.is_connected():
            con.close()
            print("Connection closed")

Full Code:

#to create a database
import mysql.connector
from mysql.connector import Error
con=None
try:
    con = mysql.connector.connect
(host='localhost',user='root',password='ct')
    if(con.is_connected()==True):
        print("connected to MYSQL Database")
        mycursor=con.cursor()
        q1="create database employee;"
        mycursor.execute(q1)
        print("Employee database created")
except Error as e:
        print(e)

finally:
        if con is not None and con.is_connected():
            con.close()
            print("Connection closed")
