如何在mysql表中插入一个点？

Question

我有一张桌子来存储客户地址。使用该地址，我正在保存几何坐标。由于某些原因，它返回错误“列'ADDRESS_LONGI_LATIT_LOCATION'不能为空”。很有可能来自““ PointFromText（@ Parameter10）”。感谢您的帮助。

这是我的代码（在C＃中）：

if (oMySQLConnecion.State == System.Data.ConnectionState.Open)
                {
                    string AddressLocation = "POINT(" + oUserLocation.Longitude + " " + oUserLocation.Latitudes + ")";

                    string Query = @"INSERT INTO address (" +
                                        "ADDRESS_TYPE," +
                                        "ADDRESS_STREET_ADDRESS_1," +
                                        "ADDRESS_STREET_ADDRESS_2," +
                                        "ADDRESS_CITY," +
                                        "ADDRESS_STATE," +
                                        "ADDRESS_ZIPCODE," +
                                        "ADDRESS_COUNTRY," +
                                        "ADDRESS_LONGI_LATIT_LOCATION) " + 
                                    "VALUES (" +
                                        "@Parameter3," +
                                        "@Parameter4," +
                                        "@Parameter5," +

                                        "PointFromText(@Parameter10));" +
                                    "SELECT LAST_INSERT_ID()";

                    MySqlCommand oCommand = new MySqlCommand(Query, oMySQLConnecion);

                    oCommand.Parameters.AddWithValue("@Parameter10", AddressLocation);
                    int sqlSuccess = oCommand.ExecuteNonQuery();
                    int AddressID = Convert.ToInt16(oCommand.LastInsertedId);
                    oMySQLConnecion.Close();
