Join multiple "exec" as one output SQL server - sql-server

Question

I'm tring to get multiple results from a dynamic exec to be columns of a table in a single output using SQL Server, right now the exec gives me multiple outputs as different temporal tables.
Is there a way to merge them together and get a single output?
This is my code:
Declare #status nvarchar(255)
Declare POINTER cursor global for select distinct status from intermedio
open POINTER
fetch NEXT from POINTER into #status
while (##FETCH_STATUS=0)
begin
exec('select distinct(
Select COUNT(*) from (
SELECT DISTINCT PKN
FROM INTERMEDIO
WHERE PIECE IN ('+'''+891''','''+75'''+') and ESTATUS = '''+#status+'''
group by PKN
having count(*)=2
) ser) as '+#status);
fetch next from POINTER into #status
end;
close POINTER;
DEALLOCATE POINTER;
Edit: Tried to explain myself better, once again excuse my poor english.
My table has three columns
+-----------+-------+---------+
| PKN | PIECE | ESTATUS |
+-----------+-------+---------+
| Set_one | +891 | A1 |
| Set_one | +75 | A1 |
| Set_one | +45 | A1 |
| Set_two | +891 | A3 |
| Set_two | +75 | A3 |
| Set_three | +700 | B1 |
+-----------+-------+---------+
I'm trying to get the count of the PKNs that have both (+891, +75) and count how many exist under ESTATUS
The output I'm expecting is something like:
+----+----+----+
| A1 | A3 | B1 |
+----+----+----+
| 1 | 1 | 0 |
+----+----+----+
But it gives me the rows on different tables.
The reason I'm doing it like this is because the table can have many different ESTATUS at any time, and many different pieces on different PKN, the result will change constantly and the table generated will be different each time I execute the query.
I'm sorry if the question isn't clear, as english is not my first language.

Answer 1

You are looking for a dynamic pivot and a conditional aggregation. Here's an example.
create table #tempTable (PKN varchar(64), PIECE varchar(64), ESTATUS varchar(2))
insert into #tempTable
values
('Set_one','+891','A1'),
('Set_one','+75','A1'),
('Set_one','+45','A1'),
('Set_two','+891','A3'),
('Set_two','+75','A3'),
('Set_three','+700','B1')
select
ESTATUS
--here is the conditional aggregation
,floor(count(case when PIECE = '+891' or PIECE = '+75' then PKN end)/2) as CT
into #staging
from
#tempTable
group by ESTATUS
DECLARE #DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE #ColumnName AS NVARCHAR(MAX)
--Get distinct values of the PIVOT Column
SELECT #ColumnName= ISNULL(#ColumnName + ',','')
+ QUOTENAME(ESTATUS)
FROM (SELECT DISTINCT ESTATUS FROM #staging) AS ESTATUS
--Prepare the PIVOT query using the dynamic
SET #DynamicPivotQuery =
N'SELECT ' + #ColumnName + '
FROM #staging
PIVOT(Sum(CT)
FOR ESTATUS IN (' + #ColumnName + ')) AS PVTTable'
--Execute the Dynamic Pivot Query
EXEC sp_executesql #DynamicPivotQuery
drop table #tempTable
drop table #staging
RETURNS
+----+----+----+
| A1 | A3 | B1 |
+----+----+----+
| 1 | 1 | 0 |
+----+----+----+
