合并和逗号分隔行

Question

我有这个查询：

SELECT
    c.br,
    c.no_,
    CONCAT(c.name, ' ', c.surname) AS Name,
    t.type,
    t.code,
    t.sub,
    GETDATE() AS date,
    c2.name 
FROM
    c 
    INNER JOIN t on c.rowno = t.rowno
    LEFT JOIN termjnt on t.rowno = termjnt.rowno
    LEFT JOIN c c2 on termjnt.rowno_c2 = c2.rowno
WHERE 
    t.status = 'active'

这是一个输出示例

如何将每个no_的c2.name行合并？ 例如，我希望单元格为“ Humphry，Heather”，而不是Heather和Humphry是不同的行

Answer 1

您可以在此处使用自连接，但问题是确定显示名称的顺序。为此，我仅使用字母名称顺序来确定序列：

WITH TEST
AS
(
SELECT 
    NAME = C.NAME+' '+C.SURNAME,
    NO_,
    ROW_NUMBER() OVER (PARTITION BY NO_ ORDER BY C.NAME+' '+C.SURNAME DESC) SEQ
FROM C
)
SELECT TEST.NO_, NAMECONCAT = TEST.NAME+', '+TEST2.NAME 
FROM TEST
    LEFT JOIN TEST TEST2
    ON TEST.NO_ = TEST2.NO_
    AND TEST.SEQ = TEST2.SEQ-1
