それでは、練習問題をひとつひとつ確認します。 Access を操作しながら、結合の理解を深めていきましょう。まず、「クエリデザイン」をクリックして、クエリを作成します。商品テーブルと商品サブカテゴリテーブルをドラッグして追加します。商品テーブルの商品数を確認しましょう。 504 レコードあります。つまり、504 個の商品データがあるということがわかります。この中のいくつかの商品は、カテゴリ分けされていません。クエリ画面に切り替え、商品テーブルを広げ、結合するフィールドを確認します。商品テーブルの商品サブカテゴリ ID フィールドと、商品サブカテゴリテーブルの同じフィールド名に結合線が表示されています。商品テーブルの商品 ID と、商品名、サブカテゴリテーブルの「商品サブカテゴリー ID」と「カテゴリー」名をデザイングリッドに挿入します。では、実行してみましょう。画面下部には、レコード数が 295 と表示されました。 504 商品のうち、内部結合を行うことで、実際に、サブカテゴリーデータを持った 295 商品のデータだけが、表示されました。続いて、デザインビューに戻り、結合方法を変更します。結合線の上で右クリックし、結合プロパティを選択します。結合方法の２番目にある、「商品テーブルの全レコードとサブカテゴリーテーブルの同じ結合フィールドのレコードだけを含める」を選択します。商品テーブルが、左テーブルなので、左外部結合であることがわかります。「OK」をクリックします。もう一度クエリを実行します。画面下部には、504 が表示されました。商品テーブルの全レコードが表示されていることが確認できましたね。「商品リストを表示する」という課題はクリアです。再び、デザインビューに切り替え、商品サブカテゴリー ID のフィールドの抽出条件に is null を使ってみましょう。実行すると、カテゴリーデータを持たない 209 商品のデータリストが表示されます。このクエリを保存する必要はありませんが、保存する場合は、サブカテゴリーのない商品という名前で保存しておきましょう。 "} </script>  </head> <body dir="ltr">   <a href="#main-content" class="skip-link btn-md btn-primary absolute z-11

を操作しながら、結合の理解を深めていきましょう。まず、「クエリデザイン」をクリックして、クエリを作成します。商品テーブルと商品サブカテゴリテーブルをドラッグして追加します。商品テーブルの商品数を確認しましょう。 504 レコードあります。つまり、504 個の商品データがあるということがわかります。この中のいくつかの商品は、カテゴリ分けされていません。クエリ画面に切り替え、商品テーブルを広げ、結合するフィールドを確認します。商品テーブルの商品サブカテゴリ ID フィールドと、商品サブカテゴリテーブルの同じフィールド名に結合線が表示されています。商品テーブルの商品 ID と、商品名、サブカテゴリテーブルの「商品サブカテゴリー ID」と「カテゴリー」名をデザイングリッドに挿入します。では、実行してみましょう。画面下部には、レコード数が 295 と表示されました。 504 商品のうち、内部結合を行うことで、実際に、サブカテゴリーデータを持った 295 商品のデータだけが、表示されました。続いて、デザインビューに戻り、結合方法を変更します。結合線の上で右クリックし、結合プロパティを選択します。結合方法の２番目にある、「商品テーブルの全レコードとサブカテゴリーテーブルの同じ結合フィールドのレコードだけを含める」を選択します。商品テーブルが、左テーブルなので、左外部結合であることがわかります。「OK」をクリックします。もう一度クエリを実行します。画面下部には、504 が表示されました。商品テーブルの全レコードが表示されていることが確認できましたね。「商品リストを表示する」という課題はクリアです。再び、デザインビューに切り替え、商品サブカテゴリー ID のフィールドの抽出条件に is null を使ってみましょう。実行すると、カテゴリーデータを持たない 209 商品のデータリストが表示されます。このクエリを保存する必要はありませんが、保存する場合は、サブカテゴリーのない商品という名前で保存しておきましょう。 </p> </div> </div> </section> </div>  <div class="tab__panel" tabindex="0" role="tabpanel" hidden> <section
