背景:クエリは、実行するたびに同じデータを返します。

これらのコードを使用して、データベースに異なるアピール数を追加します。各アピール番号には、これらのコードを介して割り当てられた割り当てコードがあります。

問題:

問題は、私は同時に2人の以上の控訴を追加するときに、このコードは唯一の追加第一の魅力に割り当て、割り当てコードを検出したが、次の追加割り当て数を検出しないです。

私のThread.sleepメソッドを追加しようとしたが、結果は同じです。

***決してEVER ***のような何かを行う 'SELECT MAX(...)+ 1 '「次の最も高い」ID番号を取得するには - これは、システムで***ちょうど***安全ではありません複数のユーザー!データベースがこれを処理するようにしてください。これらの種類のカウンタには、MS Accessの 'Autonumber'やSQL Serverの' INT IDENTITY'カラムの自動ナンバリングを使用してください。自分のロールを出そうとしないでください - データベースの内容を使用しないでください! –

どうすれば私の目的を達成できるのか教えてください。 Select MAX(..)は、データベース内の別のテーブルから次に高いIDの値を取得するために使用されます。他のテーブルから最高の値を取得するのに適したコマンドです。 –

気にしないでください。私は@@IDENTITY sqlコマンドを使用して私の問題を解決しました。あなたの貢献に感謝します。
