Question

I have a table like below:

There are multiple WebSiteIDs. I’d like the output to be like below:

Date  , WebSiteID1_Views, WebSiteID2_Views
1/1/12, 91              , 43
1/2/12, 84              , 34

(where SiteUSerID = some userdefined ID)

I’m pretty sure I need to do some sort of Join, but I cannot find the answer on Stack.

Your help is greatly appreciated!

This is the PIVOT way:

SELECT [Date],
       COALESCE([1], 0) AS WebSiteID1_Views,
       COALESCE([2], 0) AS WebSiteID2_Views
FROM (
    SELECT [Date], WebSiteID, WebSiteViews
    FROM @yourTable
    WHERE SiteUSerID = [some userdefined ID]
) AS T
PIVOT(SUM(WebSiteViews) FOR WebSiteID IN([1], [2])) AS P

… And the Non-PIVOT way:

SELECT
    [Date],
    SUM(CASE WebSiteID WHEN 1 THEN WebSiteViews ELSE 0 END) AS WebSiteID1_Views,
    SUM(CASE WebSiteID WHEN 2 THEN WebSiteViews ELSE 0 END) AS WebSiteID2_Views
FROM @yourTable
WHERE SiteUSerID = [some userdefined ID]
GROUP BY Date
