python mysql操作

引入数据库的包

import MySQLdb

连接数据库
conn=MySQLdb.connect(host='localhost',user='root',passwd='123456',db='test',port=3303,charset='utf8')
#创建游标
cur=conn.cursor()

sql1="insert into user (title,name,content) values (%s,%s,%s)"

#cur.executemany("insert into user (title,name,content) values (%s,%s,%s)",[('test05','z05','test content05'),('test06','zz06','test content06'),])
#cur.execute("insert into user (title,name,content) values ('test05','z05','test content05'),('test06','zz06','test content06')")
#conn.commit()
#返回有影响的行数
print cur.execute("select * from user")
#返回全部
print cur.fetchall()
print cur.fetchall()
#返回size条
print cur.fetchmany(size)
#返回一条
print cur.fetchone()
#从当前行移动到value
cur.scroll(value,mode='relative')

#从结果集移到value行
cur.scroll(value,mode='absolute')

踩过的坑：

连接的时候端口号不能加引号，不然会报错：TypeError: an integer is required

execute 和executemany 用法区别：

cur.execute("insert into user (title,name,content) values ('test05','z05','test content05'),('test06','zz06','test content06')")

cur.executemany("insert into user (title,name,content) values (%s,%s,%s)",[('test05','z05','test content05'),('test06','zz06','test content06'),])
