2つのクエリQuery1があります。
with cte as (
select
dbo.Cable.*,
row_number() over(partition by dbo.Cable.TagNo order by dbo.Cable.CableRevision desc) as rn
from dbo.Cable
where (dbo.Cable.CableRevision = @CoreRevision )
)
select *
from cte
where rn = 1
また、Query2
with cte as (
select
dbo.Cable.TagNo,dbo.Core.*,
row_number() over(partition by dbo.Core.CoreNo order by dbo.Core.CoreRevision desc) as rn
from dbo.Core INNER JOIN
dbo.Cable ON dbo.Cable.Id = dbo.Core.CableId
where (dbo.Core.CoreRevision <= @CoreRevision )
)
select *
from cte
where rn = 1
これら2つのクエリはQuery1.TagNo
およびQuery2.TagNo
これら2つのクエリを結合するにはどうすればよいですか。With
コマンドを使用してそれを行うことはできますか?
ありがとうございました
このクエリを試してください。おそらくこれがあなたが探しているものです。
;WITH cte AS
(SELECT dbo.Cable.*,
row_number() over(partition by dbo.Cable.TagNo order by dbo.Cable.CableRevision desc) as rn
FROM dbo.Cable
WHERE dbo.Cable.CableRevision = @CoreRevision
), cte2 AS
(SELECT dbo.Cable.TagNo, dbo.Core.*,
row_number() over(partition by dbo.Core.CoreNo order by dbo.Core.CoreRevision desc) as rn
FROM dbo.Core INNER JOIN dbo.Cable ON dbo.Cable.Id = dbo.Core.CableId
WHERE dbo.Core.CoreRevision <= @CoreRevision
)
SELECT *
FROM cte c FULL JOIN cte2 c2 ON c.TagNo = c2.TagNo
WHERE c.rn = 1 OR c2.rn = 1
with cte as
(
select
dbo.Cable.*,
row_number() over(partition by dbo.Cable.TagNo order by dbo.Cable.CableRevision desc) as rn
from dbo.Cable
where (dbo.Cable.CableRevision = @CoreRevision )
),
cte2 as (
select
dbo.Cable.TagNo,dbo.Core.*,
row_number() over(partition by dbo.Core.CoreNo order by dbo.Core.CoreRevision desc) as rn
from dbo.Core INNER JOIN
dbo.Cable ON dbo.Cable.Id = dbo.Core.CableId
where (dbo.Core.CoreRevision <= @CoreRevision )
)
select *
from cte
join cte2 on cte1.TagNo = cte2.TagNo
where cte.rn = 1 and cte2.rn = 1;
条件cte.rn = 1 and cte2.rn = 1
が適切かどうかはわかりません。たぶん、どちらか一方のCTEでそれが必要な場合もあれば、両方の場合もあるでしょう。実際には、結合条件にcte2.rn = 1
を使用した外部結合が必要な場合もあります...
