MySql的參數必須定義MVC

Question

我有這個代碼在這裏：

var sql = "select shr_id, shc_id " + 
         "from tbox_operational.shipment_ref " + 
         "inner join tbox_operational.shipment_collo_ref using (shr_id) " + 
         "where shr_insdtm between ?dateTimeFrom"; 

var parameters = new List<MySqlParameter> { 
              new MySqlParameter("?dateTimeFrom", dateTimeFrom.ToString("yyyy/MM/dd HH:mm:ss"))                
              }; 

      var query = (from db in context.Database.SqlQuery<ShridsModel>(sql, parameters) 
         select db).ToList(); 

      return query; 

但它讓我得到這個錯誤：

{"Parameter '?dateTimeFrom' must be defined."} 

我也有我的連接字符串：

server=xxx;user id=runtime;password=xxxx;AllowUserVariables=True; 

我在這裏做錯了什麼？
