データ型nvarcharを小数点以下を使用して変換する

Question

私はクライアントのために構築しているジョブ原価計算レポートを持っています。彼らの勘定科目表には小数点以下10桁（1001.55）が含まれています。私は何をしていても、nvarcharを浮動小数点、整数または数値に変換することはできません。私がCOA 5310でフィルタリングしようとしている最後のWhere節を取り出した場合、問題なく実行されます。どのような目立つ明白な問題が私は見落としていますか？どんな助けもありがとう！

Answer 1

感謝をBさんの答えの後ろの説明はHです。これは実際にはID10Tエラーだったときの解決策の単純化の問題でした。文字列値（一重引用符）にint（引用符なし）を使用することはできません。

Answer 2

あなたの問題がありそうなので一部をたまたま行の COA.Numberのsは数値ではありません。あなたは、次のクエリでこれを確認することができます。

select * from COA where ISNUMERIC(COA.Number) <> 1 

今、あなたはそれらの行を修正するか、または逆に、あなたの新しいテーブルを作成している間、あなたはそれらを除外することができます。@Jacobへ

WHERE ISNUMERIC(COA.Number) = 1
