sql ID 按顺序串联在单独的列中，如运行总计

Question

我需要运行 ID 串联，就像运行余额或总计一样.. 将之前的 ID 逐行连接到当前的 Id，如图所示

查询是

with relation (Id, [orderSequence])  
as  
(  
select Id,cast(Id as varchar(20))  
from [ACChartofAccount]  

union all  
select p.Id, cast(Cast(r.Id as varchar) + ',' + cast(p.Id as varchar) as varchar(20))  
from [ACChartofAccount] p  
inner join relation r on p.ParentId = r.Id 
)  

select Id,orderSequence 
from relation  
order by orderSequence

Answer 1

您可以使用下面的查询来获得上面的结果。

DECLARE @Table TABLE(ID VARCHAR(10));
INSERT INTO @table(ID) VALUES ('320'),(332),(333),(334),(335);
SELECT mt.ID,
    STUFF((  
        SELECT ', ' + ID 
        FROM @table t
        WHERE t.ID <= mt.ID 
        FOR XML PATH('')), 1, 2, '') AS oldersequence
FROM @table mt 
ORDER BY ID
