Q:

Dapper using ODBC store procedure Input parm always promt @XXX was not supplied

I need help from All Dapper master.
I have been learning using Dapper since one month ago, but I have error when executing query using ODBC SP. 
The code originally was written by someone(DapperExample) but not using ODBC, thanks to the writer I forgot your name.
My SP:
CREATE PROCEDURE SP_GET_FIND_EMPLOYEES (@EmpID INT)
AS
BEGIN 
    SET NOCOUNT ON;
    SELECT * FROM tblEmployee WHERE EmpID = @EmpID
END
GO

My Code
public class EmployeeDashBoard : IEmployeeDashBoard
    {
    private IDbConnection _db;
    string connStr2 = WebConfigurationManager.ConnectionStrings["DapperExample"].ConnectionString;

    public EmployeeDashBoard()
    {

    }

    public Employee Find(int id)
    {

        //type b, by sp 
        using (IDbConnection connection = new OdbcConnection(connStr2))
        {

            var p = new DynamicParameters();

                p.Add("@EmpID", id);

            Employee result = this._db.Query<Employee>("dbo.SP_GET_FIND_EMPLOYEES", new { @EmpID = id }, commandType: CommandType.StoredProcedure).Single();
            return result;

        }

    }

}

Error:
ERROR [42000] [Microsoft][SQL Server Native Client 11.0][SQL Server]Procedure or function 'SP_GET_FIND_EMPLOYEES' expects parameter '@EmpID', which was not supplied.
Thanks in Advance.

A:

I Solved by my self, I'm using Sybase ODBC SP, ( God Job Sam ), now I can avoid entity framework in the feature.
Here the tricks: 

Solved: SP_GET_FIND_EMPLOYEES ? 

        using (IDbConnection connection = new OdbcConnection(connStr2))
        {

            var p = new DynamicParameters();

            p.Add("?EmpID?", id.ToString()); 

            Employee result = this._db.Query<Employee>("dbo.SP_GET_FIND_EMPLOYEES ?", p, commandType: CommandType.StoredProcedure).Single();
            return result;
        }
