sql - sorting large amounts of urls by top domain in mysql -



sql - sorting large amounts of urls by top domain in mysql -

a mysql database i'm working has thousands of urls. now, lot of urls same domain, each 1 have differing sub-domains , page names. e.g.

somewebsite.com/gj29sjw somewebsite.com/29shw0a somewebsite.com/92jslwa anothersite.net/jfdkden anothersite.net/hj2892j anothersite.net/282j290

etc...

is there query or syntax can utilize both grouping urls , count them in largest first order, without subdomains , page names. ideally, after run count query, need get:

somewebiste.com | 345 anothersite.net | 289

you utilize substring_index create query simple; take 2 lastly period separated groups before first slash;

select substring_index(substring_index(url, '/', 1), '.', -2) site, count(*) cnt mytable grouping site;

an sqlfiddle test with.

note good performance on query, i'd recommend storing site name separately, doing calculations on each ro not give ultimate performance.
