Python操作MySQL简单实现方法
本文实例讲述了Python操作MySQL简单实现方法。分享给大家供大家参考。具体分析如下：
一、安装：
安装MySQL
安装MySQL不用多说了，下载下来安装就是，没有特别需要注意的地方。

二、示例：
复制代码 代码如下:
# coding=utf-8
import MySQLdb
#查询数量
def Count(cur):
count=cur.execute('select * from Student')
print 'there has %s rows record' % count
#插入
def Insert(cur):
sql = "insert into Student(ID,Name,Age,Sex)values(%s,%s,%s,%s)"
param = (2,'xiaoming',24,'boy')
cur.execute(sql,param)
#查询
def Select(cur):
n = cur.execute("select * from Student")
print "------"
for row in cur.fetchall():
for r in row:
print r
print "------"
#更新
def Update(cur):
sql = "update Student set Name = %s where ID = 2"
param = ("xiaoxue")
count = cur.execute(sql,param)
#删除
def Delete(cur):
sql = "delete from Student where Name = %s"
param =("xiaoxue")
n = cur.execute(sql,param)
try:
conn=MySQLdb.connect(host='localhost',user='root',passwd='123456',db='python',port=3306)
cur=conn.cursor()
#数量
Count(cur)
#查询
Select(cur)
#插入
Insert(cur)
print "插入之后"
#查询
Select(cur)
#更新
Update(cur)
print "更新之后"
#查询
Select(cur)
#删除
Delete(cur)
print "删除之后"
#查询
Select(cur)
cur.close()
conn.close()
except MySQLdb.Error,e:
print "Mysql Error %d: %s" % (e.args[0], e.args[1])
import MySQLdb
#查询数量
def Count(cur):
count=cur.execute('select * from Student')
print 'there has %s rows record' % count
#插入
def Insert(cur):
sql = "insert into Student(ID,Name,Age,Sex)values(%s,%s,%s,%s)"
param = (2,'xiaoming',24,'boy')
cur.execute(sql,param)
#查询
def Select(cur):
n = cur.execute("select * from Student")
print "------"
for row in cur.fetchall():
for r in row:
print r
print "------"
#更新
def Update(cur):
sql = "update Student set Name = %s where ID = 2"
param = ("xiaoxue")
count = cur.execute(sql,param)
#删除
def Delete(cur):
sql = "delete from Student where Name = %s"
param =("xiaoxue")
n = cur.execute(sql,param)
try:
conn=MySQLdb.connect(host='localhost',user='root',passwd='123456',db='python',port=3306)
cur=conn.cursor()
#数量
Count(cur)
#查询
Select(cur)
#插入
Insert(cur)
print "插入之后"
#查询
Select(cur)
#更新
Update(cur)
print "更新之后"
#查询
Select(cur)
#删除
Delete(cur)
print "删除之后"
#查询
Select(cur)
cur.close()
conn.close()
except MySQLdb.Error,e:
print "Mysql Error %d: %s" % (e.args[0], e.args[1])
