一、安装MySQL-python

# yum install -y MySQL-python

二、打开数据库连接

#!/usr/bin/pythonimport MySQLdbconn = MySQLdb.connect(user='root',passwd='admin',host='127.0.0.1')conn.select_db('test')cur = conn.cursor()

三、操作数据库

 

def insertdb():    sql = 'insert into test(name,`sort`) values ("%s","%s")'    exsql = sql % ('hello','python')    cur.execute(exsql)    conn.commit()    return 'insert success'def selectdb():    sql = 'select `name` from test where `sort` = "%s"'    exsql = sql % ('python')    count = cur.execute(exsql)    for row in cur:        print row    print 'cursor move to top:'    cur.scroll(0,'absolute')    row = cur.fetchone()    while row is not None:        print row        row = cur.fetchone()    print 'cursor move to top:'    cur.scroll(0,'absolute')    many = cur.fetchmany(count)    print manydef deletedb():    sql = 'delete from test where `sort` = "%s"'    exsql = sql % ('python')    cur.execute(exsql)    conn.commit()    return 'delete success'print insertdb()print insertdb()selectdb()print deletedb()

 

四、关闭连接

cur.close()conn.close()

注意顺序。
