之前写的时候忘记提醒大家数据一定要备份，操作数据库的情况一定要备份，不然就麻烦了。
论坛看了好多帖子还是不行自己弄出来了！
delete from dede_addonarticle;
delete from dede_addonimages;
delete from dede_archives;
delete from dede_arctiny;
delete from dede_co_htmls;
delete from dede_co_urls;
delete from dede_co_mediaurls;
delete from dede_tagindex ;
delete from dede_taglist;
delete from dede_keywords;
在后台直接运行上面的语句，意思是清空文章和原来采集过的记录
TRUNCATE TABLE `dede_archives`;
再在后台直接运行上面的语句
TRUNCATE TABLE `dede_archives`;
使用SQL的清空表的命令。ID就会从1开始。
dede文章删除后 id从1开始设置方法
只需要执行三条SQL语句就可以了：


ALTER TABLE `dede_archives` AUTO_INCREMENT =1;
ALTER TABLE `dede_arctiny` AUTO_INCREMENT =1;
ALTER TABLE `dede_addonarticle` AUTO_INCREMENT =1;
