phpのLaravelフレームワークで100行ぐらいのSELECT文を書いてみようと思い投稿させていただきました。
また私は、MySQL、php、Laravel初心者です。よろしくお願いいたします。
バージョン
- MySQL 8.0.13
- php 7.2
- Laravel 5.7
データはsakilaを使用させていただきましたm(_ _)m
参考：
注意
本来LaravelのEloquentを使うとhasOne hasMany belongsToなどのリレーションの機能(Eloquent: Relationships - Laravel - The PHP Framework For Web Artisans)がものすごく便利なのですが、あえてこの機能は使わずにSQLで頑張ろうと思いました。
また、100行ぐらいとタイトルに書いてしまったのであえて長くなるような書き方にしたり、viewを使わないという冗長な書き方をしています。
また、LaravelのORMで初心者から職人へ - Qiitaでメンテしにくいコードに進むパターンと紹介されていることをそのまま行いますので、実務では決して今回の内容と同じようなコードは書いてはいけません。
よろしくお願いいたします。
全ての顧客とそれに関連する情報を色々
抽出単位
- customer_id単位で一意になるように抽出
抽出項目
- 顧客名
- 国名
- レンタルしたfilmの直近3つをカンマ区切り
- 最後にレンタルした日
- 今までレンタルした総数
- 全顧客の平均レンタル数
- country単位の平均レンタル数
- city単位の平均レンタル数
- 顧客のレンタル合計数が平均数より大きい場合は1、平均数以下の場合は0、それを
全ての顧客の平均とcountry単位の平均とcity単位の平均をカンマ区切りで表示する
例：顧客Aのレンタル合計数は全体の平均以上、country単位の平均以下、city単位の平均以上だった場合は「1,0,1」
-
↑の条件で一つでも平均以上があれば1、一つもなければ0
-
rental_rateが1以上のfilmの今までの合計rate
-
rental_rateが1より小さいfilmの今までの合計rate
-
rental_rateが1以上のfilmの直近で借りたfilmのcategory
- ↑ただしcustomerの総レンタル数が20以上の場合のみ出力する
-
rental_rateが1より小さいfilmの直近で借りたfilmのcategory
- ↑ただしcustomerの総レンタル数が25以上の場合のみ出力する
-

メンテナンス性を考えると普通にsql書くのとあまり変わらなさそうです
2005/06〜2005/08を月ごとに、カテゴリー単位でamountを出力
抽出単位
2005年6〜8月 x カテゴリー数となるように
ただし、カテゴリー「Action」「Animation」「Children」はさらにstore単位になるようにする
抽出条件
- 以下の条件に当てはまるものは合計amountから除くこととする
- 除外条件1 以下の全ての条件に当てはまる顧客が借りた場合
- countoryが以下のいずれか
- Brazil
- China
- Mexico
- categoryが以下のいずれか
- Action
- Drama
- 顧客単位でその月で2回以上レンタルしている場合
- countoryが以下のいずれか
- 除外条件2 以下の全ての条件に当てはまる顧客が借りた場合
- countoryが以下のいずれか
- Brazil
- China
- Mexico
- Russian Federation
- South Africa
- categoryが以下のいずれか
- Action
- Animation
- 顧客が属するcity単位で、その月のレンタル数が最低数と同等の顧客
- countoryが以下のいずれか
- 除外条件3
- cityが以下のいずれか
- Vicente Lpez
- Tandil
- Stara Zagora
- Vancouver
- Richmond Hill
- Oshawa
- Warren
- Tallahassee
- Sunnyvale
- 以下のいずれか
- categoryがAction、かつ7〜8月にレンタルされていた場合
- categoryがAnimation、かつ6〜7月にレンタルされていた場合
- ↑ただしcountryがUnited States、かつ6〜8月の場合は除外しない
- cityが以下のいずれか
- 除外条件1 以下の全ての条件に当てはまる顧客が借りた場合
抽出項目
- 月
- カテゴリー名
- store_id -> store単位カテゴリーはstore_idを、そうでないものはnull
- 合計amount
- 先月の合計amount
- 今月と先月のamountの差分
