一、安裝MySQL-python
# yum install -y MySQL-python
二、打開數(shù)據(jù)庫(kù)連接
#!/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、操作數(shù)據(jù)庫(kù)
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 many
def 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、關(guān)閉連接
cur.close()
conn.close()
注意順序。
