将一列数据转换成一个字段数据，逗号分隔
这个场景很常见，在网上查了一下，人家说用xpath 方法，亲测有效。
select stuff(
(select ','+cast(u.UserName_Chn as varchar(max)) from BO_ManagementPeo b inner join V_P_UserInfo
u on u.UserGUID = b.UserGUID where a.ObjectGUID=b.ObjectGUID for xml path(''))
,1,1,'') as JoinUsers, ObjectGUID
from BO_ManagementPeo a
group by ObjectGUID
如果只是单个
select a.*,
stuff(
(select ','+cast(FullName as varchar(max)) from erp.dbo.yx_khinfo where CHARINDEX('首利', FullName) > 0 for xml path(''))
,1,1,'') fullname
from (select '首利' col1) a
