加入两个查询

我想加入这两个查询：加入两个查询

InventoryItemID，似乎无法使其工作。我已经尝试了很多解决方案，但无法围绕它解决问题。我正在使用Microsoft SQL。

select t1.itemcode, t1.Description, t1.MinimumQuantity, t1.QuantityInStore, t2.qty as OnOrder, t1.InventoryItemID 
from 
    (
select i.InventoryItemID, i.ItemCode, i.Description, MinimumQuantity, ii.QuantityInStore 
    from InventoryInfo i 
    inner join InventoryStoreInfo ii 
     on i.InventoryItemID = ii.inventoryitemid 
    inner join PurchaseOrderItemInfo p 
     on ii.InventoryItemID = p.InventoryItemID 
    inner join PurchaseOrderInfo po 
     on p.PurchaseOrderID = po.PurchaseOrderID 
    inner join VendorInfo v 
     on po.VendorID = v.VendorID 
    where InventoryCategoryID = '1' 
    and i.IsActive = '1' 
    ) as t1 
left join 
    (
select InventoryItemID, sum(Quantity) as QTY, Description 
    from PurchaseOrderItemInfo p 
    inner join PurchaseOrderInfo po 
     on p.PurchaseOrderID = po.PurchaseOrderID 
    where p.status = '0' 
    group by InventoryItemID, Description 
    ) as t2 
on t1.inventoryitemid = t2.inventoryitemid

和

select pi.InventoryItemID, v.VendorName, max(p.PODateTime) as latest 
from PurchaseOrderItemInfo pi 
inner join PurchaseOrderInfo p 
    on pi.PurchaseOrderID = p.PurchaseOrderID 
inner join InventoryInfo i 
    on pi.InventoryItemID = i.InventoryItemID 
inner join VendorInfo v 
    on p.VendorID = v.VendorID 
group by pi.inventoryitemid, p.PODateTime,i.description, v.VendorName 
order by latest desc

这是什么问题？ –

您是否在寻找select * from（查询1转到这里）q1 JOIN（查询2转到这里）q2 on q1.InventoryItemID = q2.InventoryItemID' – Blorgbeard

我提供的两个查询都有共同的inventoryitemid，我想将查询2中的日期添加到查询1 – JeffreyLazo

你包括号之间的每个查询创建子查询(queryA)和(queryB)

然后assing别名每个子查询和perfom联接

SELECT aliasA.*, aliasB.* 
FROM 
    (queryA) aliasA 
INNER JOIN (queryB) aliasB 
    ON aliasA.ID = aliasB.ID

使用您的查询

SELECT FIRSTQUERY.*, SECONDQUERY.* 
FROM 
    (
    select t1.itemcode, t1.Description, t1.MinimumQuantity, t1.QuantityInStore, t2.qty as OnOrder, t1.InventoryItemID 
    from 
     (
     select i.InventoryItemID, i.ItemCode, i.Description, MinimumQuantity, ii.QuantityInStore 
     from InventoryInfo i 
     inner join InventoryStoreInfo ii 
      on i.InventoryItemID = ii.inventoryitemid 
     inner join PurchaseOrderItemInfo p 
      on ii.InventoryItemID = p.InventoryItemID 
     inner join PurchaseOrderInfo po 
      on p.PurchaseOrderID = po.PurchaseOrderID 
     inner join VendorInfo v 
      on po.VendorID = v.VendorID 
     where InventoryCategoryID = '1' 
     and i.IsActive = '1' 
     ) as t1 
    left join 
     (
     select InventoryItemID, sum(Quantity) as QTY, Description 
     from PurchaseOrderItemInfo p 
     inner join PurchaseOrderInfo po 
      on p.PurchaseOrderID = po.PurchaseOrderID 
     where p.status = '0' 
     group by InventoryItemID, Description 
     ) as t2 
    on t1.inventoryitemid = t2.inventoryitemid 
    ) FIRSTQUERY 
    INNER JOIN 
    (
    select pi.InventoryItemID, v.VendorName, max(p.PODateTime) as latest 
    from PurchaseOrderItemInfo pi 
    inner join PurchaseOrderInfo p 
     on pi.PurchaseOrderID = p.PurchaseOrderID 
    inner join InventoryInfo i 
     on pi.InventoryItemID = i.InventoryItemID 
    inner join VendorInfo v 
     on p.VendorID = v.VendorID 
    group by pi.inventoryitemid, p.PODateTime,i.description, v.VendorName 
    order by latest desc 
    ) SECONDQUERY 
    ON FIRSTQUERY.InventoryItemID = SECONDQUERY.InventoryItemID
