查詢哪裏關聯在續集？

where子句在內部連接中使用。我的查詢是查詢哪裏關聯在續集？

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代碼寫的是

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

它產生的錯誤是：

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代碼應該是這樣的：

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%' 
      } 
     } 
    }] 
});

要選擇例如只有一些屬性，您可以使用attributes選項。 where子句應該在include聲明中移動，因爲您使用的條件與hp_state模型相關。

，感謝您的答覆，我知道你都貼什麼，但我想在狀態COUNTRY_ID的列名包括框，因爲我要檢查這種情況下，看這裏[ （Cou.country_status = 1 AND Sta.state_status = 1 AND Cou.country_id = 1） AND（Sta.state_name LIKE'％ta％'）;] –

@SimhaChalam看來我還沒有正確理解你，已經更新了上面的代碼以滿足您的所有條件。 –

ok .. thanq .. so much alex M –

hp_country.findAll({
