數據庫中沒有條目？但是，這個錯誤信息並沒有

我寫了這段代碼但是它沒有在數據庫中列出，會顯示消息是否成功插入？數據庫中沒有條目？但是，這個錯誤信息並沒有

if (txtdate.Text != "" && txtalireza.Text != "" && txtdatekamel.Text != "" && txthasan.Text != "" && txtkarbar.Text != "" && txtkarkard.Text != "" && txtkharid.Text != "" && txtmoj.Text != "" && txttozih.Text != "") 
      { 

       SqlConnection con = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirector y|\Resources\dbcn.mdf;Integrated Security=True;User Instance=True"); 
       SqlCommand com = new SqlCommand(); 
       com.Connection = con; 
       com.CommandText="INSERT INTO newbuy(byname,datekol,dateshort,karkard,kharidha,b arali,barhasan,barmoj,descrip)VALUES(@byname,@date kol,@dateshort,@karkard,@kharidha,@barali,@barhasa n,@barmoj,@descrip)"; 
       com.Parameters.AddWithValue("@byname",txtkarbar.Te xt); 
       com.Parameters.AddWithValue("@datekol", txtdatekamel.Text); 
       com.Parameters.AddWithValue("@dateshort", txtdate.Text); 
       com.Parameters.AddWithValue("@karkard",txtkarkard. Text); 
       com.Parameters.AddWithValue("@kharidha",txtkharid. Text); 
       com.Parameters.AddWithValue("@barali",txtalireza.T ext); 
       com.Parameters.AddWithValue("@barhasan",txthasan.T ext); 
       com.Parameters.AddWithValue("@barmoj",txtmoj.Text) ; 
       com.Parameters.AddWithValue("@descrip",txttozih.Te xt); 
       con.Open(); 
       com.ExecuteNonQuery(); 

       MessageBox.Show("inserted"); 

       con.Close(); 
      } 
      else 
      { MessageBox.Show("error"); }`

@date & KOL之間remove space從值括號

com.CommandText="INSERT INTO newbuy(byname,datekol,dateshort,karkard,kharidha,b arali,barhasan,barmoj,descrip)VALUES(@byname,@date kol,@dateshort,@karkard,@kharidha,@barali,@barhasa n,@barmoj,@descrip)";到

com.CommandText="INSERT INTO newbuy(byname,datekol,dateshort,karkard,kharidha,b arali,barhasan,barmoj,descrip)VALUES(@byname,@datekol,@dateshort,@karkard,@kharidha,@barali,@barhasa n,@barmoj,@descrip)";
