I understand the error, I have no idea how to fix this. Maybe i wrote this wrong but I should have more then 1 count? I should have a count for each url? I want to only display urls and how many times it repeated when there is more then 1.

    I don’t know about mySQL but in MSSQL I would do

    select count(url) as c, url from PageInfo group by url having count(url) > 1;

    so the changes are change the count(*) to count(url) and move your filter in to the having clause (and putting an additional count there as you can’t reference the name in the select clause in the having clause).
