--I have this and it is not flexible

SELECT convert(varchar(20),a.sdate, 108),UID,
MIN( CASE b.UID WHEN 1 THEN b.sdesc END ),
MIN( CASE b.UID WHEN 2 THEN b.sdesc END ),
MIN( CASE b.UID WHEN 3 THEN b.sdesc END )
FROM #dayview a
LEFT JOIN #events b ON a.sdate=b.sdate
GROUP BY a.sdate, UID
ORDER BY a.sdate

--I want to do this

DECLARE @count int
DECLARE @x int
SET @x= 1
SET @count=3
DECLARE @sql nvarchar(1000)
WHILE @x <= @count
BEGIN

@sql = @sql + 'MIN( CASE b.UID WHEN ' + @x + 'THEN b.sdesc END )',
@x=@x+1
END

SELECT convert(varchar(20),a.sdate, 108), @sql,
FROM #dayview a
LEFT JOIN #events b ON a.sdate=b.sdate
GROUP BY a.sdate, UID
ORDER BY a.sdate

Not sure how to get there.
Thanks
