Можете да направите това с динамичен PIVOT
и ROW_NUMBER()
функция:
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 – отделен списък, специфичен ред
Редактиране:Ако не искате списъкът да е различен, елиминирайте първия cte по-горе и ако искате да запазите произволно подреждане, променете ORDER BY
към (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 - пълен списък, произволен ред
И накрая, ако не искате RowRank
полето в резултатите си, просто използвайте повторно @cols
променлива във вашия 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)
