Answer 1

Groupがキーワード（SelectとfromのようなSQLで特別な意味を持つ言葉）であるので、あなたにエラーを与えて、その。このGroupはGroup Byと競合しており、これを列名として使用しています。テーブルのカラム名は、GroupnameまたはGroupTypeのようにSQLのキーワードではないものに変更する必要があります。これでエラーは解決します。

Answer 2

Groupという名前の列があるようですが、それはキーワードなので、厳密なコーディングの変更が必要ない場合は列名を変更するか、単にこれを[]のペアで囲むことをお勧めします[Group]。そのようなキーワードを他の目的のために与えるのは良い習慣ではないことに留意してください。すでに他の目的のために予約されています。
