いくつかのデータモデリングを試みています。ゲーム、マッチ、ターン テーブルで 2 つのボットを追跡しようとしています。これらのボットはボット テーブルに一覧表示されます。前述の 3 つのテーブルでは、外部キーを 2 回 (ボットごとに 1 回) 表示する必要があります。
このデータベースは、2 つの AI が互いに競合した結果を記録することを目的としています。
これがモデルにとって適切な方法であるかどうかはわかりませんが、これを実装しようとすると errorno: 150 が発生します。この問題を解決する方法がわかりません。ヘルプとアドバイスをいただければ幸いです。以下にリストされている SQL コード。
