#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)

#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])

二、示例：
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()
