嗨獲取地圖上的標識，上面的表我必須要通過invId，我需要地圖Id是誰在OriginalInvID列結果。

例如：

• 如果我通過1然後我得到1
• 如果我通過4然後我得到3,4,5-
• 如果我通過8然後我得到6像這樣

Answer 1

您可以使用while循環來獲取父親和子女7,8,9節點將它們存儲在臨時表：

declare @myInvId int 
declare @father_counter int 
declare @children_counter int 
declare @temp table (Id int, InvID int, InvDate datetime, OriginalInvID int, FilterDesc nvarchar(100)) 
declare @fathers table(id int, status int) 
declare @children table(id int, status int) 

insert into @temp 
      select 1, 1, '2017-03-01 00:00:00.000', 0, 'First Inv Created' 
union all select 2, 2, '2017-03-06 00:00:00.000', 1, 'Link ID' 
union all select 3, 3, '2017-03-01 00:00:00.000', 0, 'First Inv Created' 
union all select 4, 4, '2017-03-03 00:00:00.000', 3, 'Link ID' 
union all select 5, 5, '2017-03-06 00:00:00.000', 4, 'Second Inv Created on top of MapID' 
union all select 6, 6, '2017-03-01 00:00:00.000', 0, 'First Inv Created' 
union all select 7, 7, '2017-03-03 00:00:00.000', 6, 'Link ID' 
union all select 8, 8, '2017-03-05 00:00:00.000', 7, 'Second In Created on top of Map Id' 
union all select 9, 9, '2017-03-06 00:00:00.000', 8, 'Second Inv Created on top of Map Id' 

--set input parameter 
set @myInvId = 8 

--init counters 
set @father_counter = 1 
set @children_counter = 1 

--insert starting node 
insert into @fathers select InvID,0 from @temp where OriginalInvID = @myInvId 
insert into @children select OriginalInvID,0 from @temp where InvID = @myInvId 

--loop on table 
while (@father_counter + @children_counter) > 0 
    begin 
     --fetch father nodes 
     insert into @fathers select InvID, 1 from @temp where OriginalInvID in (select id from @fathers where status=0) 
     --update fathers' status 
     update @fathers set status = 2 where status = 0 
     update @fathers set status = 0 where status = 1 

     --fetch children nodes 
     insert into @children select OriginalInvID, 1 from @temp where InvID in (select id from @children where status=0) 
     --update children's status 
     update @children set status = 2 where status = 0 
     update @children set status = 0 where status = 1 

     --update counters 
     select @father_counter = count(*) from @fathers where status = 0 
     select @children_counter = count(*) from @children where status = 0 
    end 

select @myInvId 
union 
select id from @fathers 
union 
select c.id from @children c inner join @temp t on c.id = t.InvID

如果我明白你想要什麼，我想你想這樣的查詢：

declare @InvId int = 8; 
with cte(Id, InvID, InvDate, OriginalInvID) as (
    select * 
    from yourTable 
    where OriginalInvID = @InvId 
    union all 
    select t.* 
    from yourTable t join cte on t.InvId = cte.OriginalInvID 
) 
select * 
from cte 
order by Id;
