Vous pouvez le faire avec le PIVOT dynamique et le ROW_NUMBER() fonction :
DECLARE @cols AS VARCHAR(1000),
@query AS VARCHAR(8000)
SELECT @cols = STUFF((SELECT ',' + QUOTENAME(Name)
FROM (SELECT DISTINCT Name
FROM #test
)sub
ORDER BY Name
FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)')
,1,1,'')
PRINT @cols
SET @query = '
WITH cte AS (SELECT DISTINCT *
FROM #test)
,cte2 AS (SELECT *,ROW_NUMBER() OVER(PARTITION BY Name ORDER BY Apt)RowRank
FROM cte)
SELECT *
FROM cte2
PIVOT (max(Apt) for Name in ('[email protected]+')) p
'
EXEC (@query)
SQL Fiddle - Liste distincte, ordre spécifique
Modifier :si vous ne voulez pas que la liste soit distincte, éliminez le premier cte ci-dessus, et si vous voulez garder un ordre arbitraire, changez le ORDER BY à (SELECT 1) :
DECLARE @cols AS VARCHAR(1000),
@query AS VARCHAR(8000)
SELECT @cols = STUFF((SELECT ',' + QUOTENAME(Name)
FROM (SELECT DISTINCT Name
FROM #test
)sub
ORDER BY Name
FOR XML PATH(''), TYPE).value('.', 'VARCHAR(MAX)')
,1,1,'')
PRINT @cols
SET @query = '
WITH cte AS (SELECT *,ROW_NUMBER() OVER(PARTITION BY Name ORDER BY (SELECT 1))RowRank
FROM #test)
SELECT *
FROM cte
PIVOT (max(Apt) for Name in ('[email protected]+')) p
'
EXEC (@query)
SQL Fiddle - Liste complète, ordre arbitraire
Et enfin, si vous ne vouliez pas le RowRank champ dans vos résultats, réutilisez simplement le @cols variable dans votre SELECT :
SET @query = '
WITH cte AS (SELECT *,ROW_NUMBER() OVER(PARTITION BY Name ORDER BY (SELECT 1))RowRank
FROM #test)
SELECT '[email protected]+'
FROM cte
PIVOT (max(Apt) for Name in ('[email protected]+')) p
'
EXEC (@query)
