需要注意的是，这行代码你需要进行一些修改
1.请您将tuzi123_数据表前缀修改为你的discuz数据表前缀，默认是pre_
2.修改set price = 0后面的0为你要设置的discuz附件售价，如果你要清零附件售价，请填写0

ccode('update tuzi123_forum_attachment_0 set price = 0;
update tuzi123_forum_attachment_1 set price = 0;
update tuzi123_forum_attachment_2 set price = 0;
update tuzi123_forum_attachment_3 set price = 0;
update tuzi123_forum_attachment_4 set price = 0;
update tuzi123_forum_attachment_5 set price = 0;

update tuzi123_forum_attachment_7 set price = 0;
