SQL-根据最大值加入查询
我正在尝试将具有成本数据的CTE加入具有现有库存数据的另一CTE。我正在尝试使用主要的“现有” CTE，成本数据CTE（MAUCPvt）中只有1个值，这是每个WVG和商品代码的最新日期和最新序列。我附加了获得的结果和所需输出的图像。我相信这是子查询中的内容，因为我非常接近所需的输出，但是在这种情况下，我想忽略该项目。当我删除select max（project）时，我得到“子查询返回的值超过1”。这是我的查询：

编辑：：还尝试使用ROW_NUMBER（），但预期结果却需要> 12分钟才能完全运行，这是因为ROWNUMBER索引扫描。必须有一种简便的方法可以实现这一点。

您可以尝试对子查询使用OUTER JOIN
SELECT distinct t2.*,t1.WAUC_WVG
FROM (
SELECT *,(SELECT top 1 [TotalCost] FROM CTE1 ORDER BY TransDate desc) WAUC_WVG
FROM CTE1
) t1
RIGHT JOIN CTE2 t2 on t1.WVG = t2.WVG and t1.Warehouse = t2.Warehouse
编辑
如果有很多Item，您可以尝试一下。
;with tradeCte as (
SELECT *,ROW_NUMBER() OVER(PARTITION BY Item ORDER BY TransDate desc) rn
FROM CTE1
)
SELECT distinct t2.*,t1.WAUC_WVG
FROM (
SELECT *,(SELECT top 1 [TotalCost]
FROM tradeCte tt
WHERE tt.rn = 1 and tt.Item = t1.Item
ORDER BY TransDate desc) WAUC_WVG
FROM tradeCte t1
) t1
RIGHT JOIN CTE2 t2 on t1.WVG = t2.WVG and t1.Warehouse = t2.Warehouse

弄清楚了。通过在子查询中添加前1个，可以在15秒左右的时间内获得所需的结果，而使用ROW_NUMBER（）则需要近15分钟。
