Question

I would like to show a filtered result to a few ip’s that keep scraping my content. I have blocked them with .htaccess and they change their ip address and continue doing it. So I thought, I want to create a soft block that won’t show them all of my content and hopefully they won’t even notice.

My table has a auto_increment field

 id | category |  everything else
 1       1
 2       1
 3       4
 4       2

I have been trying something like this.

SELECT * from mytable WHERE `category` = '1' having avg(id/3) = 1 ORDER BY `id` DESC LIMIT 0 , 10

I have searched forever but I am a newb to sql, so I don’t even really know what I am searching for. I hope somebody here can please help me! Thanks 🙂

If you want to get remainder of division by 3, you should use % operator.

SELECT * from mytable WHERE `category` = '1' and id % 3 = 1 ORDER BY `id` 
DESC LIMIT 0 , 10
