第一点:织梦DEDECMS的文章是分别存储在三个表里面[addonarticle],[archives],[arctiny]通过addonarticle.aid、archives.id、arctiny.id关联,删除文章时,应该删除三个表里的记录.
第二点:执行SQL可以从PHPMYADMIN，或者DEDECMS后台系统设置-SQL命令行工具里
第三点:本次手动删除内容为空或者字数少于200的文章,分了两步分别删除两个表,总结代码如下:
1:查看要删除文章的代码:
select * from addonarticle where length(body)<200
2:删除内容表.
delete from addonarticle where length(body)<200 delete from addonarticle where length(body)<200
3:查看要删除文章的第二个表的代码:
left join addonarticle t2 on t1.id=t2.aid 04.where t2.aid is null and t1.channel=1 select *
from archives t1
left join addonarticle t2 on t1.id=t2.aid
where t2.aid is null and t1.channel=1
4:删除第二个表.代码如下:
left join addonarticle t2 on t1.id=t2.aid 04.where t2.aid is null and t1.channel=1 DELETE archives t1
from archives t1 –Cuoxin.com
left join addonarticle t2 on t1.id=t2.aid
where t2.aid is null and t1.channel=1
5:查看要删除文章的第三个表的代码:
left join addonarticle t2 on t1.id=t2.aid 04.where t2.aid is null and t1.channel=1 select *
from arctiny t1
left join addonarticle t2 on t1.id=t2.aid
where t2.aid is null and t1.channel=1
6:删除第三个表.代码如下:
left join addonarticle t2 on t1.id=t2.aid 04.where t2.aid is null and t1.channel=1
如果你不查看的话,直接执行第2,4,6步就可以了,其中t1.channel=1是只操作普通文章类别的意思,防止删除软件等其他类别.
