Combining data from 2 rows into 1 - row

Question

I have an extremely complex query. I want the 2 row data combine in to 1 row.
It gives me the following Output
PNAME RN LVN HA MSW SC
AA AG-1W SS-1M LO-2W PA-1W SK-1M
AA JL-1W TD -1M NULL NULL NULL
IS there any way I could have the results in 1 Row or Combine the 2 Rows in to 1. Like As Follows.
PNAME RN LVN HA MSW SC
AA AG-1W SS-1M LO-2W PA-1W SK-1M
JL-1W TD -1M NULL NULL NULL

It is not exactly clear what you are trying to achieve, but you can implement usage of row_number() to prevent the pname from showing in additional rows:
select case when rownum = 1 then pname else '' end pname,
[RN], [LVN], [HA], [MSW], [SC]
from
(
select pname, disc, value,
ROW_NUMBER() over(partition by disc order by disc) rownum
from temp
) src
pivot
(
max(value)
for disc in ([RN], [LVN], [HA], [MSW], [SC])
) piv
See SQL Fiddle with demo
results:
| PNAME | RN | LVN | HA | MSW | SC |
----------------------------------------------------
| AA | AG-1W | SS-1M | LO-2W | PA-1W | SK-1M |
| | JL-1W | TD-1M | (null) | (null) | (null) |
This uses to the value of the row_number() to decide if the pname should be displayed. It will only show the value when the rownum=1, otherwise it will be blank.
If you want the data in a single row, you can use something similar to the following:
;with cte as
(
select pname, disc, value,
ROW_NUMBER() over(partition by disc order by disc) rownum
from temp
),
piv as
(
select *
from cte
pivot
(
max(value)
for disc in ([RN], [LVN], [HA], [MSW], [SC])
) piv
)
select pname,
STUFF((SELECT distinct ', ' + [RN]
from piv p2
where p1.pname = p2.pname
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'') RN,
STUFF((SELECT distinct ', ' + [LVN]
from piv p2
where p1.pname = p2.pname
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'') LVN,
STUFF((SELECT distinct ', ' + [HA]
from piv p2
where p1.pname = p2.pname
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'') HA,
STUFF((SELECT distinct ', ' + [MSW]
from piv p2
where p1.pname = p2.pname
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'') MSW,
STUFF((SELECT distinct ', ' + [SC]
from piv p2
where p1.pname = p2.pname
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'') SC
from piv p1
group by pname
See SQL Fiddle with Demo
The result is:
| PNAME | RN | LVN | HA | MSW | SC |
--------------------------------------------------------------------
| AA | AG-1W, JL-1W | SS-1M, TD-1M | LO-2W | PA-1W | SK-1M |
