Question

我正在查询根据表格的第三列（S）的前200位得到三列（A，B，S）（这有一些条件检查）。

SELECT TOP 200 PlantId, SKU, SUM(Demand)
FROM NetDemandTable
WHERE DemandWKId>=62 AND DemandWKId<=76
GROUP BY PlantId, SKU
ORDER BY SUM(Demand) DESC

结果列B被视为另一个选择查询的唯一记录，该查询又是A，B，S列，但条件不同，此列B应与选择查询1中获得的结果相交。

SELECT PlantId, SKU, SUM(Demand)
FROM CuringNetDemandCopy
WHERE DemandWKId < 62 
GROUP BY PlantId, SKU  
ORDER BY SUM(Demand) DESC

现在第二个查询结果应该只选择从第一个查询中获得的B列中的SKU实体。

Answer 1

试试这个：

with  cte as 
(
SELECT TOP 200 PlantId, SKU, SUM(Demand)
FROM NetDemandTable
WHERE DemandWKId>=62 AND DemandWKId<=76
GROUP BY PlantId, SKU
)

SELECT PlantId, SKU, SUM(Demand)
FROM CuringNetDemandCopy
WHERE DemandWKId < 62  and SKU in (select distinct SKU from cte)
GROUP BY PlantId, SKU  
ORDER BY SUM(Demand) DESC

SQL多选查询并在同一个表上相交
