            con.Close();
            con.Open();
            string m = "INSERT INTO Tools (TCode,TName,Description,

            cmd.ExecuteNonQuery();
            con.Close();
            MessageBox.Show("Successful!", "Message");
        }

Answer 1

不是在这里@Avaiability代替@Availability吗？

cmd.Parameters.Add("@Availability", MySqlDbType.VarChar).Value = ttAvail.Text;

请检查哪一个是您的列的正确名称：Avaiability或Availability。

谢谢。
