1.import MySQLdb;

2.與mysql資料庫建立連線：con=MySQLdb.connect(user='root',db='mysql',passwd='dingjia',host='localhost')

3.當沒有遊標cursor物件時候，連線物件可以使用query()方法，執行sql查詢

 con.query('create database test')

4.使用遊標物件和execute()方法來執行sql

cur=con.cursor()  返回遊標物件

cur.execute('create table users(login varchar(8),uid INT)')

cur.execute('insert into users values('hzhida',1000)')

cur.execute('select *from users')

for data in cur.fetchall(): 輸出查詢結果得到的資料

　　print '%s\t%s' % data

cur.close()  關閉遊標

con.commit()  提交事務

con.close()     關閉連線

python cookbook 的例子:

#-*-coding:utf-8-*-
import MySQLdb,cPickle

#連線到資料庫，並獲得圖示
connection = MySQLdb.connect(user = '
 
root',db='zm',passwd = '36039975',host='localhost')
cursor = connection.cursor()

#建立一個新表以用於試驗
cursor.execute('create table test(name TEXT, ablob BLOB)')

try:
    #準備一些BLOB用於測試
    names = 'aramis', 'athos','porthos'
    data = { }
    for name in names:
        datum = list(name)
        datum.sort()
        data[name] 
 
= cPickle.dumps(datum,2)
    #execute insert
    sql = "insert into test values(%s, %s)"
    for name in names:
        cursor.execute(sql,(name,MySQLdb.escape_string(data[name])))
    #check in the database
    sql = "select name, ablob from test order by name"
    cursor.execute(sql)
    for name , blob in cursor.fetchall():
        print name, cPickle.loads(blob), cPickle.loads(data[name])

finally:
    #finish,delete table and close connection
    cursor.execute("drop table test")
    cursor.close()
    connection.close()
輸出：

aramis ['a', 'a', 'i', 'm', 'r', 's'] ['a', 'a', 'i', 'm', 'r', 's']
athos ['a', 'h', 'o', 's', 't'] ['a', 'h', 'o', 's', 't']
porthos ['h', 'o', 'o', 'p', 'r', 's', 't'] ['h', 'o', 'o', 'p', 'r', 's', 't']
