Django游标初始化

Question

使用以下两个游标会有什么不同 - 也就是说，django如何'初始化'它的游标和连接？

（1）Django默认

from django.db import connection
conn = connection
cursor = conn.cursor()

（2）自定义初始化

import MySQLdb
self.conn = MySQLdb.connect (
                         host = settings.DATABASES['default']['HOST'],
                         port = 3306,
                         user = settings.DATABASES['default']['USER'],
                         passwd = settings.DATABASES['default']['PASSWORD'],
                         db = settings.DATABASES['default']['NAME'])

self.conn.set_character_set('utf8')
self.cursor = self.conn.cursor()
self.cursor.execute("SET NAMES utf8")
self.cursor.execute('SET CHARACTER SET utf8;')
self.cursor.execute('SET character_set_connection=utf8;')
