ODBC connection to external data

Question

Is there any way to get an ODBC-Connection to an ( external ) table from AX2012R2, without using a DSN in the ODBC-connections?

It worked fine in 2009 with something like

systemInfo = SysSQLSystemInfo::construct();

loginProperty = new LoginProperty();

loginProperty.setServer(systemInfo.getLoginServer());
loginProperty.setDatabase(systemInfo.getloginDatabase());

conString = strFmt( 'Driver={SQL Server Native Client 10.0};'
                    + 'Server=%1;'
                    + 'Database=%2;'
                    , systemInfo.getLoginServer()
                    , systemInfo.getloginDatabase()
                    );

if ( <someFunctionToCheckForTrusedConnectin> )
{
   conString += '"Trusted_Connection=Yes;"';
}
else
{
    conString += strFmt( '"id=%1;'
                        + 'pwd=%2;"'
                        , _userName
                        , _passWord
                        );
}

loginProperty.setOther( conString );

try
{
    odbc = new OdbcConnection( loginProperty);
}
catch
{
    throw error(#DatabaseConnectionError);
}

But it throws errors in 2012:

Objekt 'OdbcConnection' konnte nicht erstellt werden.
[Microsoft][ODBC Driver Manager] Der Datenquellenname wurde nicht gefunden, und es wurde kein Standardtreiber angegeben

I've googled for hours ( maybe days.. ) and didn't find any working example yet.

Edit:

If I modify the following two lines of code

loginProperty.setServer(systemInfo.getLoginServer());
loginProperty.setDatabase(systemInfo.getloginDatabase());

and enter server / database as plain text, it seems to work on first look, BUT it doesn't matter, if I enter an invalid username and/or password.

Answer 1

Why not make a system or user DSN?

This will establish a driver for the connection. You do not need to specify server or database.

Answer 2

All our interfaces use this and it works, we store our connection parameters, ie database name and database server name in a table, note the DSN is commented out, so is not necessary:

loginProperty = new LoginProperty();
loginProperty.setServer(ImportJournalParameters.ExternalServerName);
// loginProperty.setDSN("ServerSQL10");
loginProperty.setDatabase(ImportJournalParameters.ExternalDBName);
connection = new OdbcConnection(loginProperty);
info('Login Process Successful - connection established');
