python访问mysql数据库的实现方法(2则示例)

本文实例讲述了python访问mysql数据库的实现方法。分享给大家供大家参考，具体如下：

首先安装与Python版本匹配的MySQLdb

示例一

    import MySQLdb
    conn=MySQLdb.connect(user='root',passwd='123',db='example')
    cur=conn.cursor()
    cur.execute("select id,lastname,firstname, date_format(dob,'%Y-%m-%d %H-%i-%s'),phone from employee")
    ##select username,password, date_format(reg_date,'%Y-%m-%d %H-%i-%s') as date from reg_user
    for data in cur.fetchall():
      print data
    cur.close()
    conn.commit()
    conn.close()

示例二

    import MySQLdb
    conn = MySQLdb.connect(host='localhost',user='root',passwd='')
    cursor = conn.cursor()
    cursor.execute("create database python")
    cursor.execute('use python')
    cursor.execute("create table test(id int, content varchar(100))")
    #插入一条100条数据
    for i in range(1,100):
       cursor.execute("insert into test values(%s,%s)",[i,'haha'])
    #获取数据
    cursor.execute('select * from test')
    results = cursor.fetchall()
    for r in results
       print r
    conn.close()

希望本文所述对大家Python程序设计有所帮助。
