Si agrega un ROW_NUMBER() a la combinación, su pivote podrá conservar la asociación entre actividades y porcentajes.
;with cte as
(
select *, ROW_NUMBER() over (partition by name order by percentage desc) ROWNUM
from A
),
cte2 as
(
SELECT Id,Code,ROWNUM,James,James_,Sam,Sam_,Lisa,Lisa_
FROM cte
PIVOT(MAX(activity)
FOR name IN (James,Sam,Lisa)) AS PVTTable PIVOT
(
MAX(percentage)
FOR name1 IN (James_,Sam_,Lisa_)) AS PVTTable1
)
select Id, Code, MAX(James) James, MAX(James_) James_, MAX(Sam) Sam, MAX(Sam_) Sam_, MAX(Lisa) Lisa, MAX(Lisa_) Lisa_
from cte2
group by Id, Code, ROWNUM
Devoluciones:
Id Code James James_ Sam Sam_ Lisa Lisa_
1 Prashant Running 43.43 Cooking 1 73 Walking 90.34
1 Prashant Stealing 0.00 Cooking 3.43 NULL NULL
1 Prashant Lacking 0.00 NULL NULL NULL NULL
La idea es, en la primera expresión de tabla común, transformar la tabla A en esto:
Id Code percentage name name1 activity ROWNUM
1 Prashant 43.43 James James_ Running 1
1 Prashant 0.00 James James_ Stealing 2
1 Prashant 0.00 James James_ Lacking 3
1 Prashant 90.34 Lisa Lisa_ Walking 1
1 Prashant 73 Sam Sam_ Cooking 1 1
1 Prashant 3.43 Sam Sam_ Cooking 2
Y a lo largo de la consulta restante, la columna ROWNUM solo actúa para vincular el valor porcentual a la actividad.
Hacerlo dinámico es fácil una vez que tiene una consulta de trabajo. Simplemente reemplace todas las partes dinámicas (en este caso, listas de nombres delimitadas por comas, ¿verdad?) con variables. Algo como esto:
declare @sql nvarchar(max)
declare @name_concat nvarchar(max)
declare @name1_concat nvarchar(max)
declare @select_aggs nvarchar(max)
select @name_concat = STUFF((select distinct ',' + quotename(name) from A order by 1 for xml path('')), 1, 1, '')
select @name1_concat = STUFF((select distinct ',' + quotename(name1) from A order by 1 for xml path('')), 1, 1, '')
;with cte_all_names as (
select name from A
union all
select name1 from A
)
select @select_aggs = STUFF((select distinct ',MAX(' + quotename(name) + ') ' + quotename(name) from cte_all_names order by 1 for xml path('')), 1, 1, '')
select @sql = '
;with cte as
(
select *, ROW_NUMBER() over (partition by name order by percentage desc) ROWNUM
from A
),
cte2 as
(
SELECT Id,Code,ROWNUM,' + @name_concat + ',' + @name1_concat + '
FROM cte
PIVOT(MAX(activity)
FOR name IN (' + @name_concat + ')) AS PVTTable PIVOT
(
MAX(percentage)
FOR name1 IN (' + @name1_concat + ')) AS PVTTable1
)
select Id, Code, ' + @select_aggs + '
from cte2
group by Id, Code, ROWNUM
'
