Question

下面的查询产生这两行（lastinspectionid，pastduereccount）：

F5EF6588-4128-47D8-B185-002E9889D87A, htmlfromqueryrow1 
F5EF6588-4128-47D8-B185-002E9889D87A, htmlfromqueryrow2

我想将这些列连接到pastduereccount列的单行中。

似乎无法获取xml的内容以使用下面的子查询。

select lastinspectionid, PastDueRecCount2 = stuff((select ' ' + PastDueRecCount for xml path('')),1,1,'')
from
(
select lastinspectionid,   '<span style=''padding:3px;background-color:' + rowcolor + '''>' + convert(nvarchar(10),count(lastinspectionid)) + '</span>' as PastDueRecCount 
                        from
                        (
                            select [LastInspectionID], rowcolor =  case when DATEDIFF(day,[DueDate],getdate()) < 0 then '#FFCE8A' when DATEDIFF(day,[DueDate],getdate()) > 0 then '#FFA6A6'  end 
                            FROM
                            [dbo].[ReferenceRecommendations] 
                            group by [LastInspectionID],[DueDate] HAVING Count(DATEDIFF(day,[DueDate],getdate())) > -7
                        ) a
                        where rowcolor is not null
                        group by lastinspectionid, rowcolor

) as b group by lastInspectionID

然而，

cte可以在子查询中使用cte：

with cte1 as
(
select lastinspectionid, '<span style=''padding:3px;background-color:' + rowcolor + '''>' + convert(nvarchar(10),count(lastinspectionid)) + '</span>' as PastDueRecCount 
                        from
                        (
                            select [LastInspectionID], rowcolor =  case when DATEDIFF(day,[DueDate],getdate()) < 0 then '#FFCE8A' when DATEDIFF(day,[DueDate],getdate()) > 0 then '#FFA6A6'  end 
                            FROM
                            [dbo].[ReferenceRecommendations] 
                            group by [LastInspectionID],[DueDate] HAVING Count(DATEDIFF(day,[DueDate],getdate())) > -7
                        ) as a
                        where rowcolor is not null
                        group by lastinspectionid, rowcolor
 )  
 select
lastinspectionid,stuff((select' ' + PastDueRecCount from cte1 b where cte1.LastInspectionID = b.LastInspectionID for xml path('')),1,1,'')
from
 cte1 group by LastInspectionID
