当我尝试编辑/更新我的表时出现错误。这很奇怪，因为我可以很好地将新数据插入到数据库中，之后我可以删除它。我只在编辑/更新数据时遇到问题。
致命错误：未捕获的异常＆＃39; PDOException＆＃39; with message＆＃39; SQLSTATE [42000]：语法错误或访问冲突：1064 SQL语法中有错误;检查与您的MySQL服务器版本相对应的手册，以便在＃＆lt; id＆= 39; 1＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;＆＃39;在第6行＆＃39;第64行的C：\ Program Files（x86）\ Ampps \ www \ Gats \ editargat.php
