python 链接MySQL数据库

Python的DB-API 使用流程：
1、引入ＡＰＩ模块
２、获取与数据库的链接
３、执行ＳＱＬ语句和存储过程
４、关闭数据库

数据库查询操作

# encoding:utf-8
import MySQLdb
db = MySQLdb.connect("localhost","用户名","密码","数据库名")
cursor = sb.cursor()
# 使用execute方法执行SQL语句
sql = "select * from 表 where id > '%d" % (1000)
try:
    cursor.execute(sql)
    # 获取所有记录列表
    results = cursor.fetchall()
    for row in results :
        firstname = row[0]
        lastname = row[1]
        age = row[2]
        sex = row[3]
        income = row[4]
        city = row[4]
        print "firstname=%s,lastname=%s,age=%d,sex=%s,income=%d,city=%d" % (firstname,lastname,age,sex,income,city)
except:
    print "error: unable to fecth data"
# close db
db.close()
