用于MySQL的地理空间Java更新预处理语句无效

Question

我正在尝试使用以下预准备语句更新MySQL点类型：

String selectQry = ("UPDATE at_group " +
              "SET grp_country=?, grp_state=?, grp_region=?, grp_district=?, " +
              "grp_name=?, grp_section=?, grp_sub_section=?, grp_archived=?, " +
              "grp_hall_geoPoint=?, grp_nas=? " +
              "WHERE grp_id=?;");
// Create a statement and execute the query on it
            String geo = ("POINT" + "(" + latitude + " " + longditude + ")");
            ps.setString(1, country);
            ps.setString(2, state);
            ps.setString(3, region);
            ps.setString(4, district);
            ps.setString(5, group);
            ps.setString(6, section);
            ps.setString(7, subSection);
            ps.setString(8, archiveDate);
            ps.setString(9, geo);
            ps.setString(10, nas);
            ps.setString(11, groupID);

            ps.executeUpdate();

我收到以下错误：

SQLException in updateGroup: com.mysql.jdbc.MysqlDataTruncation: Data truncation: Cannot get geometry object from data you send to the GEOMETRY field

我的输入是-33.8和151.1

我按照链接（其中一些已损坏）找到了答案。我已经在这里发布了答案，为大家带来了好处。答案是：

    String selectQry = ("UPDATE at_group " +
              "SET grp_country=?, grp_state=?, grp_region=?, grp_district=?, " +
              "grp_name=?, grp_section=?, grp_sub_section=?, grp_archived=?, " +
              "grp_hall_geoPoint=PointFromText(CONCAT('POINT(', ?, ' ', ?, ')')), grp_nas=? " +
              "WHERE grp_id=?;");

// Create a statement and execute the query on it
            ps.setString(1, country);
            ps.setString(2, state);
            ps.setString(3, region);
            ps.setString(4, district);
            ps.setString(5, group);
            ps.setString(6, section);
            ps.setString(7, subSection);
            ps.setString(8, archiveDate);
            ps.setString(9, latitude);
            ps.setString(10, longditude);
            ps.setString(11, nas);
            ps.setString(12, groupID);

            ps.executeUpdate();
