I have a sql query as follows:

    SELECT
        EVENTTYPEDESCRIPTION,
        YEAR(EVENTSTARTDATE) as 'EVENTYEAR',
        COUNT(PARTICIPANTID) AS 'TOTALPARTICIPANTS'
    FROM WEBPROGRAMPARTICIPANTS
    INNER JOIN WEBPROGRAMS
        ON WEBPROGRAMPARTICIPANTS.PROGRAMCODE = WEBPROGRAMS.PROGRAMCODE
    INNER JOIN WEBEVENTS
        ON WEBPROGRAMS.PROGRAMID = WEBEVENTS.EVENTID
    INNER JOIN WEBEVENTTYPEDESCRIPTIONS
        ON WEBEVENTS.EVENTTYPE = WEBEVENTTYPEDESCRIPTIONS.EVENTTYPE
    WHERE WEBPROGRAMPARTICIPANTS.ACCEPTED = 1
    GROUP BY EVENTTYPEDESCRIPTION, YEAR(EVENTSTARTDATE)
    ORDER BY EVENTTYPEDESCRIPTION, YEAR(EVENTSTARTDATE)

Which returns the following results:

EventTypeDescripti  Year    TotalParticipants

My question is how do I reconstruct the query to show each EventTypeDescription condensed into one line and show each year as a column with its respective count

Example:

Description            Year            Year           etc...

    Thank you all for your efforts. I am going to remember the PIVOT example once our database is upgraded to 2008. For now since we are using SQL Server 2000 I decided to do the pivot within my c# code.

    It is actually better this way forme anyway, since the way Icreaetd it I can pass in any select query result and it will pivot it.
