Question

My table data is looks like:

SessionRefere  

http://www.google.com/url?sa=t&rct=j&q=aaa bbb&source=web&cd=1&cad=rja&sqi=2&ved=0CB4QFjAA&url=http://www.abc.com/&ei=QFR0UM-JKIrQrQfsuoG4CQ&usg=AFQjCNExYcKkcvobBbktLGNksptf1giQRw

It’s only sample data.There are many cases like this. So I want original url part before count.

I use this query to get data.

DECLARE @temp table(RefPage nvarchar(200))
insert into @temp
SELECT
   CASE CHARINDEX( '?', SessionReferer)
       WHEN 0 THEN SessionReferer
       ELSE LEFT(SessionReferer, CHARINDEX( '?', SessionReferer) - 1) END AS RefPage 
FROM Tracker WHERE [start] between '1-1-2010' and '1-1-2015' and  SessionReferer<> ''

 select distinct RefPage, count(*) as [VisitTime] from @temp
  group by RefPage
order by [VisitTime] desc

and my result is:

SessionRefere                           VisitTime
http://www.google.com/url                 2
http://www.google.com/reader/view/        1 

But I want a result:

SessionRefere                           VisitTime
http://www.google.com                      3

Is it possible to get desire result or I am in wrong way? Thanks.

Answer 1

Try splitting at CHARINDEX('/',SessionReferrer,9)

 select 
   case when CHARINDEX('/',SessionReferrer,9) = 0 
     then SessionReferrer
     else left(SessionReferrer, CHARINDEX('/',SessionReferrer,9)-1)
   end,
   count(*)
 from Tracker      
 group by
   case when CHARINDEX('/',SessionReferrer,9) = 0 
     then SessionReferrer
     else left(SessionReferrer, CHARINDEX('/',SessionReferrer,9)-1)
   end

(I am lazily assuming all your referrers start with http:// or https://)
