Django之复杂SQL语句处理方式

extra

models.userinfo.objects.extra(select={'n1': "select count(1) from tb1 where id>%s",'id':'id','name':'name'},select_params=(11,))

等同于

select
id,
name,
(select count(1) from tb1 where id>11) as n1
from
table

原生SQL

from django.db import connection, connections

cursor = connections['default1'].cursor()
####cursor = connection.cursor()

cursor.execute("""SELECT * from auth_user where id = %s""", [1])
row = cursor.fetchone()

不懂得可以参考：

PS:根据Django源码写的快速增删改查的组件，希望对各位有点帮助！
