本篇内容主要讲解“sqlserver怎么合并列数据”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“sqlserver怎么合并列数据”吧!
sql server 递归查询树型结构某节点的所有上级节点，并且把这些所有上级节点多行拼接为一行，即合并列数据
with eps_root(pk_eps, pk_parent, eps_code, eps_name) as( SELECT pk_eps, pk_parent, eps_code, eps_name FROM pm_eps where enablestate = 2 and pk_eps = '1001A11000000003P62E' union all SELECT e.pk_eps, e.pk_parent, e.eps_code, e.eps_name FROM pm_eps e inner join eps_root r on e.pk_eps = r.pk_parent where e.enablestate = 2)select distinct eps_code = stuff((select '/' + convert(nvarchar(500), eps_code) from (select distinct eps_code from eps_root) r1 for xml path('')), 1, 1, ''),--此次需要使用eps_code排序，不然中文的会错乱顺序eps_name = stuff((select '/' + eps_name from (select top 99.99 PERCENT eps_name from eps_root order by eps_code) r2 for xml path('')), 1, 1, '')from eps_root执行sql，如下图效果：
