python--如何操作表

>>> import MySQLdb

>>> conn=MySQLdb.connect(user='admin',passwd='',host='192.168.31.212')

>>> cur=conn.cursor() #创建游标

>>> conn.select_db('zsw')

第一种方法插入数据>>> cur.execute("insert into person(number,name,birthday) value(1,'zhaosunwei','1984-11-28')")

1L

第二种方法插入数据（推荐）>>> sqli="insert into person(number,name,birthday) value(%s,%s,%s)"

>>> cur.execute(sqli,(3,'liujilei','1982.05.06'))

1L

插入多条数据>> sqli="insert into person(number,name,birthday) values(%s,%s,%s)"

>>> cur.executemany(sqli,[(4,'sunjingbo','1964.08.01'),(5,'cuizhongjun','1964,11,29')])

2L

删除数据>>> cur.execute('delete from person where number=4')

1L

更新数据>>> cur.execute("update person set name='sunbo' where number=3")

1L

选择数据>>> cur.execute("select * from person")

4L

一条一条的取数据>>> cur.fetchone()

(1L, 'zhaosunwei', datetime.date(1984, 11, 28))

>>> cur.fetchone()

(2L, 'cuixiuxiu', datetime.date(1987, 8, 13))

>>> cur.fetchone()

(3L, 'sunbo', datetime.date(1982, 5, 6))

>>> cur.fetchone()

(5L, 'cuizhongjun', datetime.date(1964, 11, 29))

>>> cur.fetchone()

游标移到最开始位置>>> cur.scroll(0,'absolute')

>>> cur.fetchone()

(1L, 'zhaosunwei', datetime.date(1984, 11, 28))

多条数据同时取>>> cur.fetchmany(cur.execute("select * from person"))

((1L, 'zhaosunwei', datetime.date(1984, 11, 28)), (2L, 'cuixiuxiu', datetime.date(1987, 8, 13)), (3L, 'sunbo', datetime.date(1982, 5, 6)), (5L, 'cuizhongjun', datetime.date(1964, 11, 29)))

游标关掉>>> cur.close()

链接关掉>>> conn.close()
