Sql 将列值合并为一行

我有一个具有这种结构的平板电脑：

Usr    Key        Value
Peter   Address    78 Street
Peter   Number     123456
Peter   Sport      Rugby
Peter   Document   ABCDE

我想询问一下：

NAME  Address   Number Sport Document
Peter 78 Street 123456 Rugby ABCDE

谁能帮我？

如果每个用户的每个键只有一个值：

select P.*
from Table1 as t
pivot (
    max(Value)
    for [Key] in ([Address], [Number], [Sport], [Document])
) as P

或

有关PIVOT语句的更多信息，请查看此页。至于你的问题，这里有一个例子可以说明如何做到：

--create temp table and populate it
SELECT 'NAME' AS [KEY], 'Peter' AS VALUE
INTO #tmp
UNION ALL
SELECT 'Address' AS [KEY], '78' AS VALUE
UNION ALL
SELECT 'Number' AS [KEY], '1' AS VALUE
UNION ALL
SELECT 'Sport' AS [KEY], 'Rugby' AS VALUE
UNION ALL
SELECT 'Document' AS [KEY], 'qwretz' AS VALUE

--check what's in here
SELECT [KEY], VALUE FROM #tmp

--pivot
SELECT [NAME], [Address], [Number], [Sport], [DOCUMENT]
FROM
( SELECT [KEY], VALUE FROM #tmp) AS SourceTable
PIVOT
( MAX(VALUE)
FOR [KEY] IN ([NAME], [Address], [Number], [Sport], [DOCUMENT])
) AS PivotTable
