prova questo:
set nocount on;
declare @t table (id char(36), x char(1))
insert into @t (id, x)
select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'A' union
select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'B' union
select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'C' union
select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'D' union
select '7ce953ca-a55b-4c55-a52c-9d6f012ea903' , 'E' union
select '7ce953ca-a55b-4c55-a52c-9d6f012ea903' , 'F'
set nocount off
SELECT p1.id,
stuff(
(SELECT
' ' + x
FROM @t p2
WHERE p2.id=p1.id
ORDER BY id, x
FOR XML PATH('')
)
,1,1, ''
) AS YourValues
FROM @t p1
GROUP BY id
USCITA:
id YourValues

MODIFICA
in base al commento di OP su questa necessità di essere eseguita per una query esistente, prova questo:
;WITH YourBugQuery AS
(
--replace this with your own query
select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' AS ColID , 'A' AS ColX
union select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'B'
union select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'C'
union select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'D'
union select '7ce953ca-a55b-4c55-a52c-9d6f012ea903' , 'E'
union select '7ce953ca-a55b-4c55-a52c-9d6f012ea903' , 'F'
)
SELECT p1.ColID,
stuff(
(SELECT
' ' + ColX
FROM YourBugQuery p2
WHERE p2.ColID=p1.ColID
ORDER BY ColID, ColX
FOR XML PATH('')
)
,1,1, ''
) AS YourValues
FROM YourBugQuery p1
GROUP BY ColID
questo ha gli stessi risultati impostati come mostrato sopra.
