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

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

There should be no space between the N and the Unicode enclosed string.
"UPDATE TableNameXXX SET ColumnNameXXX = N 'Executive Chair эюя' WHERE PKEYXXX = 'AS000008'"
should be
"UPDATE TableNameXXX SET ColumnNameXXX = N'Executive Chair эюя' WHERE PKEYXXX = 'AS000008'"
