列と行のグループ化と切り替え

動的 PIVOT でこれを行うことができます および ROW_NUMBER() 関数:

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 ('example@sqldat.com+')) p
            '
EXEC (@query)

SQL Fiddle - 個別のリスト、特定の順序

編集:リストを区別したくない場合は、上記の最初の cte を削除し、任意の順序を維持したい場合は ORDER BY を変更します (SELECT 1) へ :

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 ('example@sqldat.com+')) p
            '
EXEC (@query)

SQL Fiddle - 完全なリスト、任意の順序

最後に、RowRank が必要ない場合は、 結果のフィールド、@cols を再利用するだけです SELECT の変数 :

SET @query = '
WITH cte AS (SELECT *,ROW_NUMBER() OVER(PARTITION BY Name ORDER BY (SELECT 1))RowRank
             FROM  #test)
SELECT 'example@sqldat.com+' 
FROM  cte 
PIVOT (max(Apt) for Name in ('example@sqldat.com+')) p
            '
EXEC (@query)
