Percentuale di SQL Server 2005 tra parentesi nella tabella pivot

Puoi formattare il risultato della tua query pivot come faresti con qualsiasi altra. Quindi, potresti concatenare la percentuale alla rispettiva fonte. Ecco un FIDDLE SQL .

SELECT RC.lessonid AS 'lessonid     response count->'
  , convert (varchar(20), isnull([0], 0))
  + isnull (' ('
-- As both numbers are integers don't forget to cast one of them into double
-- If you dislike * 100 format or want more precise result.
  + convert (varchar(20), [0] * 100 / RCN.N)
  + '%)', '') as [0]
  , convert (varchar(20), isnull([1], 0))
  + isnull (' ('
  + convert (varchar(20), [1] * 100 / RCN.N)
  + '%)', '') as [1]
  , convert (varchar(20), isnull([2], 0))
  + isnull (' ('
  + convert (varchar(20), [2] * 100 / RCN.N)
  + '%)', '') as [2]
  , convert (varchar(20), isnull([3], 0))
  + isnull (' ('
  + convert (varchar(20), [3] * 100 / RCN.N)
  + '%)', '') as [3]
  , convert (varchar(20), isnull([4], 0))
  + isnull (' ('
  + convert (varchar(20), [4] * 100 / RCN.N)
  + '%)', '') as [4]
  ,RCN.N
FROM (
    SELECT lessonid
        ,response
        ,count(response) AS respcnt
    FROM tblRChoices
    GROUP BY lessonid
        ,response
    ) TableResponseCount
PIVOT(SUM(respcnt) FOR response IN (
