提前可能很重要的信息：

Access 2003 Database (*.mdb)
Table is Linked to SQL Server 2005 Database --> Table
When linked to another Access Database --> Table it works

Program which i use to update : .net 2.0 based C#
Databaselanguage: German?
OleDbConnection used:
 Connection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;" +
                                                 "Data Source=" + PathToDatabase + ";" +
                                                 "Jet OLEDB:System Database=" + PathToSystemFile+ ";" +
                                                 "User ID=" + SignedUserID + ";" +
                                                 "Password=" + SignedLoginKey + ";");

问题：

我想更新一个字符串，我已成功解析为SQL-Update语句，如：

UPDATE [Artikel] SET [Artikelbeschreibung]='УБИТЬ ДРОЗДА 4 СЕРИИ' WHERE products_id=32501;

我的表[Artikel]包含符合要求的行（products_id = 32501）当我更新字符串时，没有抛出的错误或异常。当我检查数据库中的内容时，我只看到这个：

????? ?????? 4 ?????

来自文件的编码是UTF8，我已经尝试过但没有运气：Convert ANSI (Windows 1252) to UTF8 in C#

这是我的程序所做的步骤：

 1. Load a file containing the sql statement with placeholder / information in which file, which section, which key the right information will be
  EXAMPLE: UPDATE [Artikel] SET [Artikelbeschreibung]='<<C:\myfile.ini::MySection::MyKey>>' WHERE products_id=32501;

 2. Grab Placeholder / Information
  NOW I HAVE: <<C:\myfile.ini::MySection::MyKey>>

 3. Parse, open File, Search for Section, Search for Key, responding Value of Key as String
  RESPONSE = УБИТЬ ДРОЗДА 4 СЕРИИ

 4. Replace <<C:\myfile.ini::MySection::MyKey>> with УБИТЬ ДРОЗДА 4 СЕРИИ in Original SQL Statement
  RESULT: UPDATE [Artikel] SET [Artikelbeschreibung]='УБИТЬ ДРОЗДА 4 СЕРИИ' WHERE products_id=32501;

 5. Take the string with the Result, open OleDbConnection with Connection as described above and
    do this:
    Connection.Open();
                if (Connection != null)
                {
                    Command = null;
                    Command = Connection.CreateCommand();
                    Command.CommandText = SQL;
                    Command.ExecuteNonQuery();
                    Connection.Close();
                    Connection = null;
                }

 6. Looking into my Database there is only '????? ?????? 4 ?????' instead of 'УБИТЬ ДРОЗДА 4 СЕРИИ'

 Additional Informations: This Only occurs when my Table is linked to a SQL Server, when Table is linked to another Database or is Database directly it works fine.

也许有人可以帮助我，我不知道错误可能在哪里。

您有两种选择：

转到Regional Options并将非Unicode程序的区域设置设置为使用西里尔字符的区域设置。

将西里尔字符串转换为unicode

UnicodeFromVal应设置西里尔字母表中第一个Unicode字符的值。

Public Function AsUnicode(ByVal Source As String, UnicodeFromVal As Long) As String 
Dim c As Long
Dim ByteString() As Byte
Dim AnsiValue As Integer
Dim Length As Long
Length = Len(Source)
ByteString = StrConv(Source, vbFromUnicode, GetSystemDefaultLCID())
For c = LBound(ByteString) To UBound(ByteString)
    AnsiValue = ByteString(c)
    If AnsiValue >= 224 And AnsiValue <= 250 Then
        AsUnicode= AsUnicode & ChrW(CLng(AnsiValue - 224 + UnicodeFromVal))
    Else
        AsUnicode= AsUnicode & ChrW(AnsiValue)
    End If
Next
End Function
