Question

我有这样的数据我只想将行转换为列

以下数据

DECLARE  @Table1 TABLE   
    ( id  int,  name  varchar(20),  val  varchar(20))
;

INSERT INTO @Table1
    ( id ,  name ,  val )
VALUES
    (222, 'ram', 'match'),
    (222, 'ra', 'nomatch'),
    (222, 'man', 'nomatch'),
    (222, 'kim', 'match')
;

我需要这样的输出

ID   Match      NoMatch
222  ram,kim   ra,man

实际上我已经尝试过Pivot和Max Condition一些我错过了Point。

试试这个：

SELECT id,
       STUFF((SELECT ',' + name
              FROM @Table1 t2
              WHERE t2.id = t1.id AND val = 'match'
              FOR XML PATH('')), 1, 1, '') AS Match,
       STUFF((SELECT ',' + name
              FROM @Table1 t2
              WHERE t2.id = t1.id AND val = 'nomatch'
              FOR XML PATH('')), 1, 1, '') AS Nomatch

FROM @Table1 t1
GROUP By id
