將Unicode數據存儲在SQL Server 2008中XML數據類型

Question

我有XML數據類型作爲表列。我在其中存儲了一些XML文本。 XML文本包含一些希伯來文字符，但在我將它存儲在表格中後，所有希伯來字符都變成了「？」。我能做些什麼來解決它？

這是我的UPDATE語句：

where UID like '4' 

和SELECT語句：

SELECT * FROM Screen_Template WHERE env LIKE '" + env + "' AND OpCo LIKE '" + opco + "' AND UID LIKE '" + uid + "'" 

Answer 1

的xml數據類型完全支持Unicode和不會轉換字母問號。其他事情正在發生。這可能是以下原因之一。

1. 您的操作系統沒有正確的希伯來語字體。
2. 您客戶端應用程序的INSERT部分損壞源數據爲單字節字符集（例如，使用varchar而不是nvarchar）。
3. 您的客戶端應用程序的SELECT部分損壞表數據爲單字節字符集（例如，使用varchar而不是nvarchar）。

更新基於海報的新代碼示例：

你的INSERT語句是通過使用單字節字符串常量例如破壞Unicode文本'text'而不是Unicode常量，例如N'some文字'。你需要用大寫字母N前綴所有字符串以確保使用uNicode。
