如果不想定义model,直接执行自定义SQL,可如下操作:
1. 通过 connections获取db连接,如果是多个数据库,connections[‘dbName‘] 来选择
2. 获取游标 cursor
3. 执行sql: cursor.execute(sql)
4.获取返回结果:fetchone,fetchall (fetchall返回的是元祖,非字典)
from django.db import connections
cursor = connections[‘test_db‘].cursor() cursor.execute(‘SELECT * FROM ...‘) # fetchall返回的是元祖... users = cursor.fetchall()
