Question

我为插入国家/地区查询提供了一些代码，我需要将其更改为参数但我收到此错误：请确保所有字段的格式正确（数字字段[0-9]，日期[dd / mm / yyyy]

我在创建国家时输入了正确的格式，所以我不知道为什么会出现这个错误。原始的SQL查询已被注释掉，因此您可以看到我所做的更改。

 public static int InsertCountry(int Company_ID, string CountryISO, string CountryName, int Currency, int IsActive, int CreatedByUser, string CountryCode, string Operator, string TransitTime, string Departures, string ImportOperator, string ImportTransitTime, string ImportDepartures, decimal?

                int ID = -1;
                string sql = "proc_InsertCoutnry";

                using (MySql.Data.MySqlClient.MySqlConnection conn = new MySql.Data.MySqlClient.MySqlConnection(DataUtils.ConnectionStrings["TAT"]))

                    conn.Open();
                    using (MySql.Data.MySqlClient.MySqlCommand cmd = new MySql.Data.MySqlClient.MySqlCommand(sql, conn))
                    {
