python学习笔记十一:操作mysql

一、安装MySQL-python

# yum install -y MySQL-python

二、打开数据库连接

#!/usr/bin/python
import MySQLdb

conn = 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)
    return cur.execute(exsql)

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 many

def deletedb():
    sql = delete from test where `sort` = "%s"
    exsql = sql % (python)
    return cur.execute(exsql)


print insertdb()
print insertdb()
selectdb()
print deletedb()

四、关闭连接

cur.close()
conn.close()

注意顺序。
