SQL行转列拼接列字符

最近开发项目用到一个需要行转列并且拼接列的语句，通过网上查找整理出来如下

select ceid, SUBSTRING(names, 1, len(names)-1) from View_HearInfo AS A cross APPLY
(SELECT Expr25 + ',' FROM View_HearInfo AS B WHERE A.ceid = B.ceid group by Expr25 FOR XML PATH('') ) D (names)
where ceid = 2
GROUP BY ceid, names

主要用到cross apply 和for xml path('')

具体的看帮助吧。
