SQL Pivot without aggregation - sql-server

Question

I have a Problem converting rows in columns of a SQL Result.
My structure is like this:
GUID | PropertyName | PropertyValue
abcd | DistinguishedName | cn=abcd...
abcd| CN | cn= GROUP_
abcd| Operation | ADD
1231 | DistinguishedName| cn=123dd
1231 | Cn | cn=ASDGRUOP
1231 | Operation | DEL
There can be n PropertyNames that I dont know before, they are dynamically - i can get them through an SQL, that is not the Problem.
I want to have a structure like this:
GUID | DistinguishedName | CN | Operation
abcd| cn=abcd...| cn= GROUP_ | ADD
1231 | cn=123dd | cn=ADSGROUP | DEL
and so on.
The Column-Headers i get by this SQL:
select #cols = STUFF (( SELECT DISTINCT '],[' + x.ParameterName from ... and parametername in ('PropertyValue','DistinguishedName', 'Operation')
FOR XML PATH ('')),1,2,'') + ']'
I can do this with PIVOT-Function but because i dont have Aggregation, I cant get the right result:
set #query = N'SELECT '+ #cols + ' FROM (
SELECT x.parametervalue, x.parametername
from ... and parametername in (''PropertyValue'',''DistinguishedName'', ''Operation'')
) a
PIVOT (max(a.parametervalue) FOR ParameterName in ( ' + #cols + ')) as pv;'
exec sp_executesql #query;
I get the following result:
GUID | DistinguishedName | CN | Operation | ... other Propertys
abcd | cn=abcd... | cn = GROUP_ |ADD |...
Only 1 Result - not more. But there are like 700 Results from this query, because of the MAX() function i get only one. How can I get a Pivot without Aggregation to get all of the results?
Thank you in Advance!

Here is the dynamic PIVOT query:
DECLARE #sql NVARCHAR(MAX),
#cols NVARCHAR(MAX);
SELECT #cols =
STUFF((
SELECT DISTINCT ',' + QUOTENAME(PropertyName)
FROM #tbl
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '')
SELECT #sql =
'SELECT GUID, ' + #cols + '
FROM (
SELECT
GUID, PropertyName, PropertyValue
FROM #tbl
) t
PIVOT
(
MAX(PropertyValue)
FOR PropertyName IN(' + #cols + ')
) p ';
PRINT (#sql);
EXEC (#sql);

Another way to achieve the desired result is to use a dynamic crosstab:
DECLARE #sql NVARCHAR(MAX);
SELECT #sql =
'SELECT
GUID' + CHAR(10) +
(SELECT DISTINCT
' , MAX(CASE WHEN PropertyName = ''' + PropertyName + ''' THEN PropertyValue END) AS ' + QUOTENAME(PropertyName) + CHAR(10)
FROM #tbl
FOR XML PATH('')
) +
'FROM #tbl
GROUP BY GUID;';
PRINT (#sql);
EXEC (#sql);
