連線資料庫

from django.db import connection
    sql = "SELECT id,record_time,lose_time from old_user where lose_time>= \'" + str(today) + "\'"
    cursor = connection.cursor()

查詢資料庫

cursor.execute(sql)
results = cursor.fetchall()#查詢所有
results = cursor.fetchone()#查詢一條

更新資料庫

sql = "UPDATE old_user set lose_time=\'" + str(lose_time) + "\' where id = " + str(id)
cursor.execute(sql)
connection.connection.commit()#這裡提交用法特殊，注意
