在SQL Server 2008 XML数据类型中存储Unicode数据

我将XML数据类型作为表列。我在其中存储了一些XML文本。XML文本包含一些希伯来语字符，但在我将其存储到表中后，所有希伯来语字符都变为“？”。我能做些什么来修复它

这是我的更新声明：

xml

数据类型完全支持Unicode，不会将字母转换为问号。还有别的事情。这可能是以下原因之一

您的操作系统没有正确的希伯来文字体

客户端应用程序的

INSERT

部分正在将源数据损坏为单字节字符集（例如使用varchar而不是nvarchar）

客户端应用程序的

SELECT

部分正在将表数据损坏为单字节字符集（例如使用varchar而不是nvarchar）

根据海报的新代码示例进行更新：

INSERT语句使用单字节字符串常量（例如“text”）而不是Unicode常量（例如N“some text”），从而损坏Unicode文本。您需要在所有字符串文字前面加上大写字母N，以确保使用uNicode

UPDATE db_owner.Screen_Template
SET template_xml = 
N'<Screen> ... </Screen>'

更新db\u owner.Screen\u模板
设置模板\u xml=
N'…'

XML数据类型以UCS-2 unicode（每个字符2个字节）存储所有内容，因此基本上它应该能够很好地处理希伯来文字符。您是如何将数据插入到XML列中的？通过使用update语句，我尝试在XML文本之前添加'N'，但它仍然将每个希伯来语字符都更改为'？'似乎有什么问题？我可以更改XML数据类型排序规则吗？如果您使用的是Unicode数据类型（即nvarchar和XML）和Unicode常量（例如N'אא'）那么就不必担心排序问题了。要修复客户端应用程序，请确保在所有地方都使用Unicode数据类型和常量。问题出在DB上，因为当我生成Update语句时，数据库将xml存储为“？”字符，而不是希伯来字符。我在DB本身生成语句！
