ZIP 解凍しか試してませんが、FAMIC CSV と MACS SQLite DB の解凍は OK でした。

ところで、薬剤タブの成分テーブルについては、１成分１行表示のためには新 rac ビューによる表示しか方法がありませんが、作物タブ、病害虫タブについては、対象病害虫のカテゴリに合わせた RAC コードのみを表示した方がより親切で分かりやすいです。これを可能にするため、rac_mg に病害虫カテゴリ ID を追加し、新しい raccode というビューを作りました。
新しいテーブルとビューは、SQL タブで下記コードを実行すれば作成できます。が、すでに spec.frac.txt, spec.irac.txt, spec.hrac.txt で新テーブルとビューを作成するようにしてあるので、ACFinder 側でテンポラリテーブルとビューを作成しないようにしてもらえば OK です。

で、作物タブなら、ttTekiyoSaku を下記のように作成すれば、病害は FRAC、害虫は IRAC、雑草は HRAC の分類コードのみが表示されるようになります。病害虫タブの ttTekiyoByochu も同様です。
