Pivot in SQL 2008 R2

Question

I have table like this;

Date        PlacementName    campaignID   Impressions   Clicks   TotalConversions  Activity

01/01/2014    USA             100           5000           


        

Answer 1

The easiest way to get the result would be to use an aggregate function along with a CASE expression to convert the rows of data into columns, but you could also apply the PIVOT function.

select date,
  placementname,
  campaignid,
  impressions,
  clicks,
  sum(case when activity = 'Mobile Book' then TotalConversions else 0 end) MobileBook,
  sum(case when activity = 'Mobile TV' then TotalConversions else 0 end) MobileTV
from yourtable
group by date, placementname, campaignid, impressions, clicks;

See SQL Fiddle with Demo

select date, placementname, 
  campaignid, impressions,
  clicks,
  [Mobile Book], [Mobile TV]
from
(
  select date, placementname,
    campaignid, impressions,
    clicks, activity, totalconversions
  from yourtable
) d
pivot
(
  sum(totalconversions)
  for activity in ([Mobile Book], [Mobile TV])
) p
