java.sql.SQLDataException：ORA-01424：エスケープ文字の後に文字がありません。

Question

Oracle Express 11gをインストールしましたが、ojdbc6を使用してJavaアプリケーションからデータベース表を読み取ろうとしました。しかし、私は、次の文で例外を取得：

connection.getMetaData().getColumns(null, null, table, null); 

例外の完全なスタックトレースは次のとおりです。

私は問題が何であるかを把握することはできません。どんな助けもありがとう。

Answer 1

これは、テーブル名に'/'という文字が含まれているためです。これにはwhoes名が含まれているテーブルをエスケープしようとしています。
