次の方法でSQLクエリを実装したいと思います。
_INNER JOIN
`Product_has_ProductFeature` t ON `Product`.`id` = t.`productId` AND t.`productFeatureValueId` = 1
INNER JOIN
`Product_has_ProductFeature` t1 ON `Product`.`id` = t1.`productId` AND t1.`productFeatureValueId` = 5
_
innerJoin()
または上記のようなものを使用してこれを行うにはどうすればよいですか?
以下のコードを使用できます。
$model = Product::find()
->innerJoinWith('t', 'Product.id = T.productId')
->andWhere(['T.productFeatureValueId' => ''])
->innerJoinWith('t1', 'Product.id = T1.productId')
->andWhere(['T1.productFeatureValueId' => '5'])
->all();
$query = new \yii\db\Query();
$query->from(['u' => 'usr_user'])
->select(['u.id','p.first_name','p.last_name'])
->innerJoin(['i' => 'pdl_inspector'],'`u`.`id` = `inspector_id`')
->innerJoin(['p'=>'usr_profile'],'`p`.`user_id` = `u`.`id`')
->all();
テーブルvote_results、vote_answers、vote_questions
関係
1。投票結果> vote_answers(answer_id)
2。投票_回答> vote_questions(question_id)
$matches = Results::find()
->select(['vote_results.id', 'COUNT(vote_results.answer_id) as MatchCount'])
->innerJoin('vote_answers', 'vote_results.answer_id = vote_answers.id')
->innerJoin('vote_questions', 'vote_answers.question_id = vote_questions.id')
->andWhere(['in', 'vote_results.answer_id', 31])
->having('COUNT(vote_results.id)>=1')
->orderBy('MatchCount DESC')
->asArray()
->one();
var_dump($matches['MatchCount']);
