我有两个Query,Query1：
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
还有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
这两个查询与Query1.TagNo和Query2.TagNo相关
我如何使用连接这两个查询,是否可以使用命令？
谢谢
解决方法
尝试这个查询,也许这是你正在寻找.
;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,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
