首先，我在一個ASP.NET Web-Pages中使用帶有C＃環境的WebMatrix，它使用SQL Server Compact（SQL Server CE）。爲什麼WebMatrix在SQL Server CE中使用數據類型ntext嘗試手動編輯長字符串時出錯？（我是否需要SQL編碼）？
我以前從來沒有聽說過需要任何類型的SQL編碼，但在這種情況發生在我身上之後，我想我最好確定（我開始用谷歌搜索「SQL編碼」，雖然我確實得到了一些信息，結果並沒有真正說明我的情況，我認爲）：
我有一個數據庫，我試圖保存一個可能的大字符串。在串
agendaLines = $("#agendaText").val().split("\n");
它然後通過AJAX發送到服務器使用JSON.stringify(agendaLines)
一旦出現，而且還：
此字符串最初來自於一個HTML <textarea>元素，聚集與jQuery，像這樣表格，我只需要用簡單的INSERT聲明以及一些其他值將INSERT裝入我的數據庫。
這個長字符串插入得很好，沒有錯誤，但問題是，如果我嘗試「手動」（即不在查詢中）對該行執行某種操作，WebMatrix會拋出錯誤（我認爲必須是因爲字符如"，[,],;,,或其他可能）。這不是一個真正的問題，因爲我不打算手動編輯或刪除任何行，如果我真的需要我可以使用查詢，這似乎工作正常。但是，它確實讓我非常懷疑，由於某種原因，我是否應該預期未來會出現其他錯誤，數據庫崩潰或未來可能存在的安全漏洞。
這裏是JSON.stringify(agendaLines)輸出：

- 字段的數據類型存儲這個字符串是
ntext，因爲SQL Server CE缺少對nvarchar(max)的支持（最高可獲得的是nvarchar(4000)） - There沒有用於從數據庫中讀取此值的接口，因爲它僅用於記錄目的。
這是WebMatrix數據管理工具中的一個錯誤。嘗試使用編程方式進行更新。 –
@MikeBrind好吧，那就是我的想法。那我不覺得那麼糟糕。只是想確保我沒有爲數據庫故障或任何事情設置自己。如果您不介意快速回答，我會很樂意接受和鼓勵。再次感謝！ – VoidKing
