how to insert mutiple rows using mysql connector python code example

Example 1: python mysql insert multiple rows

import mysql.connector
from mysql.connector import Error

try:
    connection = mysql.connector.connect(host='localhost',
                                         database='Electronics',
                                         user='pynative',
                                         password='pynative@#29')

    mySql_insert_query = """INSERT INTO Laptop (Id, Name, Price, Purchase_date) 
                           VALUES (%s, %s, %s, %s) """

    records_to_insert = [(4, 'HP Pavilion Power', 1999, '2019-01-11'),
                         (5, 'MSI WS75 9TL-496', 5799, '2019-02-27'),
                         (6, 'Microsoft Surface', 2330, '2019-07-23')]

    cursor = connection.cursor()
    cursor.executemany(mySql_insert_query, records_to_insert)
    connection.commit()
    print(cursor.rowcount, "Record inserted successfully into Laptop table")

except mysql.connector.Error as error:
    print("Failed to insert record into MySQL table {}".format(error))

finally:
    if (connection.is_connected()):
        cursor.close()
        connection.close()
        print("MySQL connection is closed")

Example 2: bulk insert mysql from list of tuples

#function to transform your list into a string
def stringify(v): 
    return "('%s', '%s', %s, %s)" % (v[0], v[1], v[2], v[3])

#transform all to string
v = map(stringify, row)

#glue them together
batchData = ", ".join(e for e in v)

#complete the SQL
sql = "INSERT INTO `table_name`(`column`, `column_1`, `column_2`, `column_3`) \
VALUES %s" % batchData

#execute it
cursor.execute(sql)
db.commit()
