Utilizzo di PIVOT Puoi fare quanto segue
With SampleData AS
(
SELECT 'Team1' as Team , 'example@sqldat.com' as email, 'A' as Groups
UNION SELECT 'Team1' as Team , 'example@sqldat.com' as email, 'B' as Groups
UNION SELECT 'Team1' as Team , 'example@sqldat.com' as email, 'C' as Groups
UNION SELECT 'Team2' as Team , 'example@sqldat.com' as email, 'A' as Groups
UNION SELECT 'Team2' as Team , 'example@sqldat.com' as email, 'B' as Groups
UNION SELECT 'Team2' as Team , 'example@sqldat.com' as email, 'C' as Groups
)
SELECT Team, A, B,C FROM
(SELECT * FROM SampleData) source
PIVOT
(MAX(email) FOR Groups IN ([A], [B], [C]) )as pvt
Produce
Team A B C
----- ---------------- ---------------- ----------------
Team1 example@sqldat.com example@sqldat.com example@sqldat.com
Team2 example@sqldat.com example@sqldat.com example@sqldat.com
Guarda un esempio Data.SE
In un DB che non supporta PIVOT puoi invece fare più join alla tua tabella. Anche se potresti volerlo comunque, poiché come ha sottolineato GBN, poiché non stiamo usando un aggregato.
With SampleData AS
(
SELECT 'Team1' as Team , 'example@sqldat.com' as email, 'A' as Groups
UNION SELECT 'Team1' as Team , 'example@sqldat.com' as email, 'B' as Groups
UNION SELECT 'Team1' as Team , 'example@sqldat.com' as email, 'C' as Groups
UNION SELECT 'Team2' as Team , 'example@sqldat.com' as email, 'A' as Groups
UNION SELECT 'Team2' as Team , 'example@sqldat.com' as email, 'B' as Groups
UNION SELECT 'Team2' as Team , 'example@sqldat.com' as email, 'C' as Groups
)
SELECT
source.Team,
A.email,
B.email,
C.email
FROM
(SELECT DISTINCT TEAM From SampleData) source
LEFT JOIN SampleData A
ON source.Team = A.Team
AND A.GROUPS = 'A'
LEFT JOIN SampleData B
ON source.Team = B.Team
AND B.GROUPS = 'B'
LEFT JOIN SampleData C
ON source.Team = C.Team
AND C.GROUPS = 'C'
