How to update\insert data into a NVARCHAR column using ODBC API

Question

I am trying to update a Sybase table via Microsofts ODBC API. The following is the basics of the C++ I am trying to execute. In table, TableNameXXX, ColumnNameXXX has a type of  NVARCHAR( 200 ).
SQLWCHAR updateStatement[ 1024 ] = L"UPDATE TableNameXXX SET ColumnNameXXX = N 'Executive Chair эюя' WHERE PKEYXXX = 'VALUE'";
if( ret = SQLExecDirect( hstmt, ( SQLWCHAR* ) updateStatement, SQL_NTS ) != SQL_SUCCESS )
// Handle Error
The Sybase database has a CatalogCollation of 1252LATIN1, CharSet of windows-1252,  Collation of 1252LATIN1, NcharCharSet of UTF-8 and an NcharCollation of UCA.
Once this works for the Sybase ODBC connection I need to get it to work in various other ODBC drivers for other databases.
The error i get is "[Sybase][ODBC Driver][SQL Anywhere]Syntax error near 'Executive Chair ' on line 1"
If i take out the Unicode characters and remove the N it will update. 
Does anyone know how to get this to work? What am I missing?
I wrote a C# .net project using an ODBCConnection to a SQL Server database and am getting "sort of" the same error. I means sort of as this error contains the Unicode Text in the message whereas the Sybase ODBC error has "lost" the unicode.
static void Main(string[] args)
using (OdbcConnection odbc = new OdbcConnection("Dsn=UnicodeTest;UID=sa;PWD=password")) // ;stmt=SET NAMES 'utf8';CharSet=utf16"
//using (OdbcConnection odbc = new OdbcConnection("Dsn=Conversion;CharSet=utf8")) // ;stmt=SET NAMES 'utf8';CharSet=utf8
try
odbc.Open();
string queryString = "UPDATE TableNameXXX SET ColumnNameXXX = N 'Executive Chair эюя' WHERE PKEYXXX = 'AS000008'";
System.Console.Out.WriteLine(queryString);
OdbcCommand command = new OdbcCommand(queryString);
command.Connection = odbc;
int result = command.ExecuteNonQuery();
if( result == 1)
System.Diagnostics.Debug.WriteLine("Success");
catch(Exception ex)
System.Diagnostics.Debug.WriteLine(ex.StackTrace);
System.Diagnostics.Debug.WriteLine(ex.Message);
"ERROR [42000] [Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near 'Executive Chair эюя'."

Answer 1

Your error comes from Sybase, so I suggest you post your question to a Sybase forum.  And be aware that Sybase does not use the same tsql dialect as sql server, so you must use their dialect (if, indeed, there is any difference in this particular situation). 
One note - there should be no space between "N" and the Unicode string literal to which it applies in tsql.  E.g.,
= N'Executive Chair эюя'
not
= N 'Executive Chair эюя'
