在过去一小时我一直在尝试此查询的不同变体，但我得到错误的用户名和用户名是刚刚与用户名的普通字符串，我从XML文件中不包含特殊字符或任何获得

in the past hour i have been trying different variants of this query but i get error at the username , and the username is just a normal string with username that i get from xml file containing no special characters or whatsoever

我使用SLQ紧凑型3.5

I'm using SLQ compact 3.5

P.S我试图用？而不是@用户名也无法正常工作 所有feilds都的nchar，除了约会

P.S i tried to use ? instead of @username also not working all feilds are "nchar" except "date"

                C = nodeItem["user_from"].InnerText;
                avatar = nodeItem["user_from_avatar"].InnerText;
                string msgText = nodeItem["message"].InnerText;
                DateTime dt=DateTime.Now;

                string sql = "INSERT INTO posts(user,msg,avatar,date) VALUES(@username,@messige,@userpic,@thedate)";
                using (SqlCeCommand cmd = new SqlCeCommand(sql, connection))
                {
                    cmd.Parameters.Add("@username",C);
                    cmd.Parameters.Add("@messige", msgText.ToString());
                    cmd.Parameters.Add("@userpic", avatar.ToString());
                    cmd.Parameters.Add("@thedate", dt);
                    connection.Open();
                    cmd.ExecuteNonQuery();
                    adapter.Update(data);
                    connection.Close();
                }

该错误消息： 谢谢 ， 尼古拉·

The error msg : Thanks , Nikola

推荐答案

尽量围绕用户用方括号[用户]（以及可能的日期）。

Try surrounding 'user' with square brackets, '[user]' (and possibly date).
