比较价格变化

Question

我正在尝试创建一个视图来报告过去24小时内哪些商店的价格发生了变化。在本报告中，我需要计算并显示商店，州，城市，地址和变更金额。

这是我到目前为止所尝试过的，但它没有正确比较商店及其价格。它比较了输出中另一家商店的价格。这是一个sqlite数据库，但最终会转移到MySql。

select
   p_today.`url`,
   p_today.`company`,   
   p_today.`state`,   
   p_today.`city`,   
   p_today.`location`,   
   p_today.`address`,
   p_today.`timerecorded`,
   p_yest.price as `yesterday`,
   p_today.price as `today`,   
   p_yest.address,   
   p_yest.`timerecorded`,
   (p_today.price - p_yest.price) as `change`
from
   prices p_today
   inner join prices p_yest on
       p_today.address = p_yest.address
       and date(p_today.`timerecorded`) > date(p_yest.`timerecorded`) + datetime('now')
       and p_yest.price > 0
where p_today.price > 0
    and date(p_today.`timerecorded`) = CURRENT_DATE    
    and change > 0.1    
group by p_today.`address`
order by `change` desc
