Database Activities :

Creating a Table :

import mysql.connector 
mydb = mysql.connector.connect(

  host="localhost",

  user="yourusername",

  passwd="yourpassword",

  database: "mydatabase"

)

mycursor = mydb.cursor()

mycursor.execute("CREATE TABLE customers (name VARCHAR(255), address VARCHAR(255))")

Insert Into Table:

import mysql.connector 
mydb = mysql.connector.connect(

  host="localhost",

  user="yourusername",

  passwd="yourpassword",

  database="mydatabase"

)

mycursor = mydb.cursor()

sql = "INSERT INTO customers (name, address) VALUES (%s, %s)"

val = ("mindstick", "Allahabad")

mycursor.execute(sql, val)

mydb.commit()

print(mycursor.rowsaffected, "record inserted.")

Python MySQL Select From:

import mysql.connector 
mydb = mysql.connector.connect(

  host="localhost",

  user="yourusername",

  passwd="yourpassword",

  database="mydatabase"

)

mycursor = mydb.cursor()

mycursor.execute("SELECT * FROM customers")

myresult = mycursor.fetchall()

for x in myresult:

  print(x)

Python MySQL Order By:

import mysql.connector 
mydb = mysql.connector.connect(

  host="localhost",

  user="yourusername",

  passwd="yourpassword",

  database="mydatabase"

)

mycursor = mydb.cursor()

sql = "SELECT * FROM customers ORDER BY name"

mycursor.execute(sql)

myresult = mycursor.fetchall()

for x in myresult:

  print(x)

Delete Record:

import mysql.connector 
mydb = mysql.connector.connect(

  host="localhost",

  user="yourusername",

  passwd="yourpassword",

  database="mydatabase"

)

mycursor = mydb.cursor()

sql = "DELETE FROM customers WHERE address = 'Tashkhand marg'"

mycursor.execute(sql)

mydb.commit()

print(mycursor.rowcount, "record(s) deleted")
