查询哪里关联在续集？

where子句在内部连接中使用。我的查询是查询哪里关联在续集？

SELECT Cou.country_id,cou.country_name, Sta.state_id, Sta.state_name 
FROM hp_country Cou 
INNER JOIN hp_state Sta ON Cou.country_id = Sta.hp_country_id 
WHERE (Cou.country_status=1 AND Sta.state_status=1 AND Cou.country_id=1) 
AND (Sta.state_name LIKE '%ta%');

我sequelize代码写的是

hp_country.findAll({ 
    where: { 
     '$hp_state.state_status$': 1 
    }, 
    include: [ 
     {model: hp_state} 
    ] 
})

它产生的错误是：

SELECT `hp_country`.`country_id`, `hp_country`.`country_name`, `hp_country`.`country_status`, `hp_country`.`created_date`, `hp_country`.`update_date` FROM `hp_country` AS `hp_country` WHERE `hp_state`.`state_status` = 1; 
Unhandled rejection SequelizeDatabaseError: ER_BAD_FIELD_ERROR: Unknown column 'hp_state.state_status' in 'where clause'

你Sequelize代码应该是这样的：

hp_country.findAll({ 
    attributes: ['country_id', 'country_name'], 
    where: { 
     country_status: 1, 
     country_id: 1 
    }, 
    include: [{ 
     model: hp_state, 
     attributes: ['state_id', 'state_name'], 
     where: { 
      state_status: 1, 
      state_name: { 
       $like: '%ta%' 
      } 
     } 
    }] 
});

要选择例如只有一些属性，您可以使用attributes选项。 where子句应该在include声明中移动，因为您使用的条件与hp_state模型相关。

，感谢您的答复，我知道你都贴什么，但我想在状态COUNTRY_ID的列名包括框，因为我要检查这种情况下，看这里[ （Cou.country_status = 1 AND Sta.state_status = 1 AND Cou.country_id = 1） AND（Sta.state_name LIKE'％ta％'）;] –

@SimhaChalam看来我还没有正确理解你，已经更新了上面的代码以满足您的所有条件。 –
