Get ROWS as COLUMNS (SQL Server dynamic PIVOT query)

@bluefeet provided a very good answer utilizing the built in PIVOT functionality. However, I frequently find the PIVOT and UNPIVOT nomenclature confusing and I have yet to encounter a situation where the same results can't be achieved with standard aggregations:

select w.ws_id, w.start_date, w.end_date,
    [100.00] = isnull(sum(case when c.name='100.00' then cw.qty else null end), 0),
    [50.00]  = isnull(sum(case when c.name='50.00'  then cw.qty else null end), 0),
    [20.00]  = isnull(sum(case when c.name='20.00'  then cw.qty else null end), 0),
    [10.00]  = isnull(sum(case when c.name='10.00'  then cw.qty else null end), 0),
    [5.00]   = isnull(sum(case when c.name='5.00'   then cw.qty else null end), 0),
    [1.00]   = isnull(sum(case when c.name='1.00'   then cw.qty else null end), 0)
from workshift w
    join currency_by_workshift cw on w.ws_id=cw.ws_id
    join currency_denom c on cw.cd_id=c.cd_id
group by w.ws_id, w.start_date, w.end_date

If you want to do a dynamic pivot, you only need to build a string of the pivot columns once:

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = 
stuff(( select replace(',[@name] = isnull(sum(case when c.name=''@name'' then cw.qty else null end), 0)'
                       , '@name', rtrim(name))
        from currency_denom
        order by cd_id
        for xml path(''), type
    ).value('.', 'nvarchar(max)')
    ,1,1,'')

select @query = '
select w.ws_id, w.start_date, w.end_date, '+@cols+'
from workshift w
    join currency_by_workshift cw on w.ws_id=cw.ws_id
    join currency_denom c on cw.cd_id=c.cd_id
group by w.ws_id, w.start_date, w.end_date
'

execute(@query)

What you are trying to do is called a PIVOT. There are two ways to do this, either with a Static Pivot or a Dynamic Pivot.

Static Pivot - is where you will hard-code the values of the rows to transform to columns (See SQL Fiddle with Demo):

select ws_id,
  start_date,
  end_date,
  IsNull([100.00], 0) [100.00],
  IsNull([50.00], 0) [50.00],
  IsNull([20.00], 0) [20.00],
  IsNull([10.00], 0) [10.00],
  IsNull([5.00], 0) [5.00],
  IsNull([1.00], 0) [1.00]
from 
(
  select ws.ws_id,
    ws.start_date,
    ws.end_date,
    cd.name,
    cbw.qty
  from workshift ws
  left join currency_by_workshift cbw
    on ws.ws_id = cbw.ws_id
  left join currency_denom cd
    on cbw.cd_id = cd.cd_id
) x
pivot
(
  sum(qty)
  for name in ([100.00], [50.00], [20.00], [10.00], [5.00], [1.00])
) p

Dynamic pivot is where the columns are determined at run-time (see SQL Fiddle with Demo):

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX),
    @colsPivot AS NVARCHAR(MAX)

select @colsPivot = 
  STUFF((SELECT ', IsNull(' + QUOTENAME(rtrim(name)) +', 0) as ['+ rtrim(name)+']' 
                    from currency_denom
                   GROUP BY name
                   ORDER BY cast(name as decimal(10, 2)) desc
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

select @cols = STUFF((SELECT distinct ', ' + QUOTENAME(name)
                    from currency_denom
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')


set @query 
      = 'SELECT ws_id, start_date, end_date,' + @colsPivot + ' from 
         (
            select ws.ws_id,
              ws.start_date,
              ws.end_date,
              cd.name,
              cbw.qty
            from workshift ws
            left join currency_by_workshift cbw
              on ws.ws_id = cbw.ws_id
            left join currency_denom cd
              on cbw.cd_id = cd.cd_id
         ) x
         pivot 
         (
            sum(qty)
            for name in (' + @cols + ')
         ) p '

execute(@query)

Both versions will produce the same results.
