[转]how to inserting multiple rows in one step

To insert multiple rows in the table use executemany() method of cursor object.

Syntax:

cursor_object.executemany(statement, arguments)

• statement: string containing the query to execute.
• arguments: a sequence containing values to use within insert statement.

Let’s take an example.

from __future__ import print_function

import MySQLdb as my

db = my.connect(host="127.0.0.1",
user="root",
passwd="",
db="world"
)

cursor = db.cursor()
name = "Some new city"

country_code = 'SNC'

district = 'Someyork'

population = 10008

data = [
('city 1', 'MAC', 'distrct 1', 16822),
('city 2', 'PSE', 'distrct 2', 15642),
('city 3', 'ZWE', 'distrct 3', 11642),
('city 4', 'USA', 'distrct 4', 14612),
('city 5', 'USA', 'distrct 5', 17672),
]

sql = "insert into city(name, countrycode, district, population)
VALUES(%s, %s, %s, %s)"

number_of_rows = cursor.executemany(sql, data)
db.commit()

db.close()
