Using dapper to attach parameters with MySql
===

I got a problem using dapper to attach parameters to my MySql queries. 
Now this may be a noobish problem, but I've beaten my head on this for the better part of 2 hours now and it's still not working.

My problem is with the SelectWithParametersTest() function right in the middle.  Here is what I've got...

    using System;
    using System.Data;
    using System.Collections.Generic;
    using Dapper;

    class Program
    {
        static void Main(string[] args)
        {
            using (var dapperExample = new DapperExample())
            {
                //dapperExample.SelectTest();
                dapperExample.SelectWithParametersTest();
            }
        }
    }

    class DapperExample : IDisposable
    {
        #region Fields
        IDbConnection _databaseConnection;
        #endregion

        #region Constructor / Destructor
        public DapperExample()
        {
            _databaseConnection = new System.Data.Odbc.OdbcConnection("DSN=MySqlServer;");
            _databaseConnection.Open();
        }

        public void Dispose()
        {
            if (_databaseConnection != null)
                _databaseConnection.Dispose();
        }
        #endregion

        #region Public Methods (Tests)
        public void SelectTest()
        {
            // This function correctly grabs and prints data.
            string normalSQL = @"SELECT County as CountyNo, CompanyName, Address1, Address2
                                 FROM testdb.business
                                 WHERE CountyNo = 50 LIMIT 3";

            var result = _databaseConnection.Query<ModelCitizen>(normalSQL);
            this.PrintCitizens(result);
        }

        public void SelectWithParametersTest()
        {
            // This function throws OdbcException: "ERROR [07001] [MySQL][ODBC 3.51 Driver][mysqld-5.1.61-0ubuntu0.11.10.1-log]SQLBindParameter not used for all parameters"
            string parameterizedSQL = @"SELECT County as CountyNo, CompanyName, Address1, Address2
                                        FROM testdb.business
                                        WHERE CountyNo = ?B";
            var result = _databaseConnection.Query<ModelCitizen>(parameterizedSQL, new { B = 50 });
            this.PrintCitizens(result);
        }
        #endregion

        #region Private Methods
        private void PrintCitizens(IEnumerable<ModelCitizen> citizenCollection)
        {
            foreach (var mc in citizenCollection)
            {
                Console.WriteLine("--------");

                Console.WriteLine(mc.Address1);
                Console.WriteLine(mc.Address2);
            }
            Console.ReadKey();
        }
        #endregion
    }
