FOR VALUE IN(SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'PARAMETER_GROUP' AND TABLE_SCHEMA='COR' ORDER BY ORDINAL_POSITION ASC)
) AS u

Answer 1

Are you looking for this:
CREATE TABLE #DataSource
(
[name] SYSNAME
,[pos] INT
);
INSERT INTO #DataSource ([name], [pos])
SELECT COLUMN_NAME
,ORDINAL_POSITION
FROM INFORMATION_SCHEMA.COLUMNS
WHERE [TABLE_NAME] = 'PARAMETER_GROUP'
AND TABLE_SCHEMA='COR';
DECLARE #DynammicTSQLStatement NVARCHAR(MAX)
,#DynamicPIVOTColumns NVARCHAR(MAX);
SET #DynamicPIVOTColumns = STUFF
(
(
SELECT ',' + QUOTENAME([name])
FROM #DataSource
ORDER BY [pos]
FOR XML PATH('') ,TYPE
).value('.', 'NVARCHAR(MAX)')
,1
,1
,''
);
SET #DynammicTSQLStatement = N'
SELECT *
FROM #DataSource
PIVOT
(
MAX([pos]) FOR [name] IN (' + #DynamicPIVOTColumns + ')
) PVT';
EXEC sp_executesql #DynammicTSQLStatement;
DROP TABLE #DataSource;
I am using dynamic T-SQL statement to build the PIVOT statement in order to make it work for each table/view.

Here's your dynamic query.
declare #cols nvarchar(max);
declare #sql nvarchar(1000);
select #cols =
STUFF((select N',' + QUOTENAME([COLUMN_NAME])
from (SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'PARAMETER_GROUP' AND TABLE_SCHEMA='COR') t1
FOR XML PATH('')
), 1, 1, '') + N'';
set #sql = N'select ' + #cols + N' from
(
SELECT cast(ordinal_position as varchar(50)) as ordinal_position
, column_name FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = ''PARAMETER_GROUP'' AND TABLE_SCHEMA=''COR''
) t1
pivot
(
max(t1.ordinal_position)
for t1.column_name in (' + #cols + N')
) p '
exec sp_executesql #sql;
