TSQL Combine Multiple rows and columns - tsql

Question

I have a sql server 2008 stored proc with joins which returns multiple rows:
default ~/ / NULL NULL NULL Lorem
default ~/ / NULL NULL NULL Ipsum
I would like to return these two rows as one with the last column combined:
default ~/ / NULL NULL NULL Lorem, Ipsum
My Procedure is below
BEGIN
SET NOCOUNT ON;
SELECT
p.display_name AS Name,
p.url AS Url,
ISNULL(REPLACE(parentPage.url,'~','') + parentPage.alias,REPLACE(p.url,'~','')) as ParentPageURL,
p.page_image AS PageImage,
p.synopsis AS Synopsis,
p.metatitle AS Metatitle,
t.tag_name as tag
FROM page p
LEFT JOIN page parentPage on parentPage.id = p.parentid
LEFT JOIN page_features pf on p.id = pf.pageid and (pf.feature_type = 'TEXT' OR pf.feature_type = 'BLOG')
JOIN dbo.tag_collection_tag tc on tc.tag_collection_id = p.tag_collection_id
JOIN dbo.tag t on t.id = tc.tag_id
JOIN dbo.[Split](UPPER(#tags),',') Split on UPPER(t.tag_name) like '%' + split.Data + '%'
WHERE p.status = 'PUBLISHED'
AND p.include_in_nav = 1
AND (p.pagelevel = #level OR #level IS NULL)
AND (p.section_id = #sectionId OR #sectionId IS NULL)
ORDER BY ISNULL(REPLACE(parentPage.url,'~','') + parentPage.alias,REPLACE(p.url,'~',''))
END
Thank you.

Note if you have a column id in table page. It should be used instead of display_name
;WITH a as
(
SELECT
/*p.id,*/
p.display_name AS Name,
p.url AS Url,
ISNULL(REPLACE(parentPage.url,'~','') + parentPage.alias,REPLACE(p.url,'~','')) as ParentPageURL,
p.page_image AS PageImage,
p.synopsis AS Synopsis,
p.metatitle AS Metatitle,
t.tag_name as tag,
ISNULL(REPLACE(parentPage.url,'~','')
+ parentPage.alias,REPLACE(p.url,'~','')) XXX
FROM page p
LEFT JOIN page parentPage on parentPage.id = p.parentid
LEFT JOIN page_features pf on p.id = pf.pageid and (pf.feature_type = 'TEXT' OR pf.feature_type = 'BLOG')
JOIN dbo.tag_collection_tag tc on tc.tag_collection_id = p.tag_collection_id
JOIN dbo.tag t on t.id = tc.tag_id
JOIN dbo.[Split](UPPER(#tags),',') Split on UPPER(t.tag_name) like '%' + split.Data + '%'
WHERE p.status = 'PUBLISHED'
AND p.include_in_nav = 1
AND (p.pagelevel = #level OR #level IS NULL)
AND (p.section_id = #sectionId OR #sectionId IS NULL)
)
SELECT Name, Url, ParentPageURL, PageImage, Synopsis, Metatitle
,STUFF((
select ',' + [tag]
from a t1
-- I assume display_name is unique. I would use page.id,
-- but I am not sure you have that column
-- t1.id = t.id
where t1.display_name = t.display_name
for xml path(''), type
).value('.', 'varchar(max)'), 1, 1, '') [tags]
from a t
group by Name, Url, ParentPageURL, PageImage, Synopsis, Metatitle
ORDER BY XXX
