How Do I Insert Data To Sql Compact Server

string connetionString = null;

            connetionString = "Data Source=stockDb.sdf";

            using (SqlCeConnection con = new SqlCeConnection(connetionString))
            {
                //
                // Open the SqlConnection.
                //
                con.Open();
                //
                // The following code uses an SqlCommand based on the SqlConnection.
                //

                string sqlquery = ("insert into Enquiry(userName,cusName,cusContact,subDate,reqDate,moreDetails,tktType,noPax,firstStatus,secStatus,thirdStatus)Values(@uName,@cName,@cContact,@sDate,@rDate,@mDetails,@tType,@nPax,@fStatus,@sStatus,@tStatus)");

                SqlCeCommand command = new SqlCeCommand(sqlquery, con);


                    string submitDate = sDate.Value.ToString("yyyy-MM-dd");
                    string requireDate = mDate.Value.ToString("yyyy-MM-dd");
                    int value = Convert.ToInt32(Cus_PaxNo.Text);

                    command.Parameters.AddWithValue("@uName", Loginlbl.Text);
                    command.Parameters.AddWithValue("@cName", Cus_Name.Text);
                    command.Parameters.AddWithValue("@cContact", Cus_Contact.Text);
                    command.Parameters.AddWithValue("@sDate", submitDate);
                    command.Parameters.AddWithValue("@rDate", requireDate);
                    command.Parameters.AddWithValue("@mDetails", Cus_Details.Text);
                    command.Parameters.AddWithValue("@tType", Cus_TicketType.Text);
                    command.Parameters.AddWithValue("@nPax", value);
                    command.Parameters.AddWithValue("@fStatus", Cus_FirstStatus.Text);
                    command.Parameters.AddWithValue("@sStatus", Cus_SecondStatus.Text);
                    command.Parameters.AddWithValue("@tStatus", Cus_ThirdStatus.Text);
                    command.ExecuteNonQuery();

                        MessageBox.Show("Password Accepted");
           }
