python 使用 mysqldb 批量插入数据

转自 longriver.me

下面来大致演示一下插入数据，批量插入数据，更新数据的例子吧：

import MySQLdb
 
try:
    conn=MySQLdb.connect(host='localhost',user='root',passwd='root',port=3306)
    cur=conn.cursor()
     
    cur.execute('create database if not exists python')
    conn.select_db('python')
    cur.execute('create table test(id int,info varchar(20))')
     
    value=[1,'hi rollen']
    cur.execute('insert into test values(%s,%s)',value)
     
    values=[]
    for i in range(20):
        values.append((i,'hi rollen'+str(i)))
         
    cur.executemany('insert into test values(%s,%s)',values)
 
    cur.execute('update test set info="I am rollen" where id=3')
 
    conn.commit()
    cur.close()
    conn.close()
 
except MySQLdb.Error,e:
     print "Mysql Error %d: %s" % (e.args[0], e.args[1])

def test_insertDB():
    conn = database.Connection(host=options.mysql_host, database=options.mysql_database,
                user=options.mysql_user, password=options.mysql_password)
    sql = "insert into person(name, age, telephone) values(%s, %s, %s)"
    tmp = (('ninini', 89, '888999'), ('koko', 900, '999999'))
    conn.executemany(sql, tmp)

　　

请注意一定要有conn.commit()这句来提交事务，要不然不能真正的插入数据。
