私はphpMyAdminで作業しています。私は正常に実行され、正確に私が望むものを返すクエリを持っています。同じクエリでビューを作成すると、ビューは正常に作成されます。しかし、私はビューから選択しようとするだけで、私は次のエラーを取得：phpMyAdmin：有効なSQL - >表示、「コマンドが同期していないため、このコマンドをすぐに実行できません」

私はOracleの開発者ですので、インラインでなくてもインラインSQL文のいくつかが達成されている可能性がある場合は、事前にお詫びします。私はLEFT JOINとINNER JOINという用語を使用するのに慣れていません.OracleのOuter Joinsにはちょうど（+）を使用していましたので、簡単で（まだ非効率的な）ルートを行っただけです。
解決済み！ここにコードがあります...私のコメントの下で、私はJOINセクション（LEFT/OUTER join）にいくつかのテーブルを追加したところで動作します。私のインラインSELECTの中には何があったのか分かりませんが、今は動作しているようです。

私は私の問題を解決しました。クエリを見る時間が増えた後、私は外部結合リストにさらにいくつかのテーブルを追加して動作させました。私はまだそれらのすべてを完了していないが、私が修正したものは問題を解決したようだ。 – thePITman
