MYSQL count of count?

Question

I have a mysql table like:

id, visitorid, pageid

When a visitor hits the website it stores their visitor id and the page id as a row.

Answer 1

Try using following query

SELECT COUNT(a.page_visits) AS no_of_visitors, a.page_visits AS page_count
FROM(
SELECT COUNT(DISTINCT pageid) AS page_visits
FROM vislog
GROUP BY visid) AS a
GROUP BY a.page_visits;
