Anemone::Storage::InsertionErrorが全くわかりません。。

rubyでサイトデータをMySqlに保存する方法を勉強しています。

書籍「Rubyによるクローラー開発技法巡回・解析機能の実装と21の運用例」

書籍ではYahoo!を例に話をされており、Yahoo!はできたのですが、
他サイトで試したところ、同じようなエラーが発生してデータベースへの保存ができません。。

恐らく取得したサイト情報をMyｓｑｌに保存する際にエラがー起きているようですが、
全く解決方法がわかりません。。。

「anemone-mysql.rb」のYahoo!のURLはできて、AmazonやGoogleで試しましたが、
解決いたしましせんでした。
