私は、これらの条件に基づいて、国の数を生成するPL/SQLスクリプトを作成しようとしています条件

Question

を持つすべてのレコードを取得するレコードをループするPL/SQLスクリプト：

• 国
• 自然滞在の旅の
• 年
• 長
  • もっと
  • 少ない月1より

    

    ：最終的な目標は、（/ 1国1年）は、このような何かを得ることです

1週間以上が、1ヶ月未満1週間

より

私は単一のSQL文を手動で生成する方法を試みましたが、のPL/SQLループを使用して実行する方法がわかりません。誰かが私にどのように見せてもらえるかどうか感謝します。

以下は、関連データベースのテーブル構造です。

任意の助けをありがとう！

ここでの選択肢のカップルだ - それは本当にあなたがデータが返さたいかによって異なります。

この最初の例は、データに存在する旅行の年、国、性質の組み合わせごとに1つの行を返します。データで、私はそのタイプのない旅が存在しないので、それはオーストラリアの行とWORKを与えることはありません使用しています
