我正在使用一个prepared语句尝试向mysql表中插入新行，如果索引存在，则执行更新。我相当肯定，这个问题是有关的“点”字段标记为“grp\U霍尔\U地球点”。我收到错误：

"SQLException in updateGroup: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET grp_country='Australia', grp_state='New South Wales', grp_region='Sydney Nor' at line 1"

传递的值是：

public static void updateGroup(String state,
            String region, String district, String group, String section,
            String subSection, String archiveDate, String latitude, String longditude, String nas) {[/code]

准备好的声明是：

String insertUpdateQry = ("INSERT INTO at_group " +
                    "(grp_country, grp_state, grp_region, grp_district, grp_name, " +
                        " grp_section, grp_sub_section, grp_archived, grp_hall_geoPoint, grp_nas) " +
                    "VALUES (?, ?, ?, ?, ?, ?, ?, ?, PointFromText(CONCAT('POINT(', ?, ' ', ?, ')')), ?)" +
                    "ON DUPLICATE KEY " +
                    "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=?;");
            try {
                // Get Connection and Statement from DataSource
                c = ds.getConnection();
                ps = c.prepareStatement(insertUpdateQry);
                try {
                    // Create a statement and execute the query on it
                    ps.setString(1, "Australia");
                    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, "Australia");
                    ps.setString(13, state);
                    ps.setString(14, region);
                    ps.setString(15, district);
                    ps.setString(16, group);
                    ps.setString(17, section);
                    ps.setString(18, subSection);
                    ps.setString(19, archiveDate);
                    ps.setString(20, latitude);
                    ps.setString(21, longditude);
                    ps.setString(22, nas);
                    ps.executeUpdate();

以下是唯一索引：grp\u country、grp\u state、grp\u region、grp\u district、grp\u name、grp\u section、grp\u sub\u section
grp\ U hall\ U地质点是类型点
我使用测试数据触发更新和插入，结果相同。
