python访问mysql数据库的实现方法(2则示例)

import MySQLdb
conn=MySQLdb.connect(user='root',passwd='123',db='example')
cur=conn.cursor()
cur.execute("select id,lastname,firstname, date_format(dob,'%Y-%m-%d %H-%i-%s'),phone from employee")
##select username,password, date_format(reg_date,'%Y-%m-%d %H-%i-%s') as date from reg_user
for data in cur.fetchall():
 print data
cur.close()
conn.commit()
conn.close()

import MySQLdb
conn = MySQLdb.connect(host='localhost',user='root',passwd='')
cursor = conn.cursor()
cursor.execute("create database python")
cursor.execute('use python')
cursor.execute("create table test(id int, content varchar(100))")
#插入一条100条数据
for i in range(1,100):
 cursor.execute("insert into test values(%s,%s)",[i,'haha'])
#获取数据
cursor.execute('select * from test')
results = cursor.fetchall()
for r in results
 print r
conn.close()
