Question

I am looking for a way to connect to sybase from C# without having to setup an ODBC DSN connection locally on the machine.

Is this possible? I tried all of these different connection strings:

static private DataTable Run(string sql)
{
    var conn = new OdbcConnection();

    const string CONN_STRING2 =
        "Data Source='[myServer]';Port=5020;Database=[dbName];Uid=[user];Pwd=[pwd];";

    const string CONN_STRING1 =
        "Provider=Sybase.ASEOLEDBProvider.2;Server Name=[myServer];Server Port Address=5020;Initial Catalog=[dbName];User ID=[user];Password=[pwd];";

    conn.Open();

    var da = new OdbcDataAdapter { SelectCommand = conn.CreateCommand() };
    da.SelectCommand.CommandText = sql;
    var dt = new DataTable();
    da.Fill(dt);
    da.Dispose();
    conn.Close();

    return dt;
}

But I got an error stating:

{“ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified”}

You are using var conn = new OdbcConnection(). That is why you are getting the error.

You will need to use a sybase oledb client library. I don’t know sybase at all but last I heard one needed to purchase a third-party provider. This was almost three years ago so they may have one by now.

You would then need to do something like var connection = new ASEConnection().
