SQL server Pivot on Multiple Columns

Question

I am trying to pivot on multiple columns. I am using SQL server 2008. Here is what I have tried so far

CREATE TABLE #t ( id int, Rscd varchar(10),Accd varcha         


        

Answer 1

I would unpivot the columns into pairs first, then pivot them. Basically the unpivot process will convert the pairs of columns (rscd, position and accd, aposition) into rows, then you can apply the pivot. The code will be:

select id, [1], [2], [11], [12]
from
(
  select id, col, value
  from #t
  cross apply
  (
    select rscd, position union all
    select Accd, position + 10
  ) c (value, col)
) d
pivot
(
  max(value)
  for col in ([1], [2], [11], [12])
) piv;
