Webページの参照のためのバインド変数の結合

Question

私はwhere句の3つの異なるテーブルに対して同じ変数（：Item）を使用するこのSQLを持っています。 Oracle SQL開発者はうまく動作します。ポップアップしてItemを要求し、正しいデータを返します。
このSQLを使用してユーザーがアイテムを参照できるようにするWebページを作成したいとします。これは、Oracleデータベースに対して照会しています。 これを書き直す方法はありますか？3：Itemsを1に結合しますか？
それから私はそれをウェブページの検索フィールドとして使用します。
私はこれに親切で親切です。

Answer 1

あなたはここに2つのオプションがある -

オプション1は、使用するスクリプト言語に応じた構文を使用してWebページにこのクエリを置きます。このオプションはお勧めしません。

オプション2. Oracleでストアドプロシージャ（SP）を作成し、Webページで呼び出します。

。）SPがコンパイルされるので、これははるかに優れた選択肢であるので、より速く

Bを実行します。）これは、複数のページ/クライアントによって再使用することができます。

c）クエリが変更された場合は、SPを1つの場所（SP）に変更するだけです。

私はあなたのためにまとめたストアドプロシージャを以下に示します。IDEでコンパイルしてください。
