                   e.printStackTrace();
        //System.out.println("Error--> " + e.getMessage());
    }
    return value;

}

更新クエリを作成します

String queryString = "UPDATE account SET companyname =：companyName WHERE companyname like'm' AND Email LIKE：mailName";

このようになりますが、次のエラーが発生します。

クエリを次のように変更します

String queryString="UPDATE account SET companyname = :companyName WHERE companyname like 'm' AND email LIKE :mailName";

そして使う

query.setParameter("companyName", companyName);
query.setParameter("mailName", mailName);
