Question

我想在where子句中包含MAX日期范围的选择。我正在使用它必须把它带进来，但它错误地说"Column 'dbo.PURCHLINE.PURCHID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause."但它不会让我分组，抛出其他错误。也许我正在接近这个错误。基本上，我需要在此查询的一组列中获取最新日期：

Select 
    PURCHLINE.PURCHID as 'PO'
    ,SUBSTRING(Cast(Max(VENDPACKINGSLIPJOUR.DELIVERYDATE) as varChar), 0, 12) as 'DeliveryDate'
    ,PURCHLINE.QTYORDERED as 'QtyOrdered'
FROM dbo.PURCHLINE 
    INNER JOIN dbo.INVENTTABLE 
        ON dbo.PURCHLINE.ITEMID = dbo.INVENTTABLE.ITEMID 
    INNER JOIN dbo.INVENTITEMGROUP 
        ON dbo.INVENTTABLE.ITEMGROUPID = dbo.INVENTITEMGROUP.ITEMGROUPID 
    INNER JOIN dbo.INVENTPOSTING 
        ON dbo.INVENTITEMGROUP.ITEMGROUPID = ITEMRELATION 
    INNER JOIN dbo.PURCHTABLE 
        ON dbo.PURCHLINE.PURCHID = dbo.PURCHTABLE.PURCHID 
    INNER JOIN dbo.LEDGERTABLE 
        ON LEDGERACCOUNTID = ACCOUNTNUM 
    INNER JOIN VENDPACKINGSLIPJOUR 
        on VENDPACKINGSLIPJOUR.PURCHID = PURCHLINE.PURCHID
WHERE
    dbo.PURCHLINE.PURCHSTATUS = 3 --open Order
    AND dbo.PURCHLINE.PURCHASETYPE = 3 --Purchase Order
    AND dbo.PURCHLINE.DIMENSION IN (@department)
    AND INVENTACCOUNTTYPE = 0 --Purchase Packing Slip
    AND PURCHLINE.DIMENSION2_ = @division
    HAVING Max(VENDPACKINGSLIPJOUR.DELIVERYDATE) between @start and @end

Answer 1

您有一个聚合，因此您需要对nonaggregate字段进行分组：

GROUP BY
     PURCHLINE.PURCHID
    ,PURCHLINE.QTYORDERED

这在HAVING子句之前。

要求Group By子句并且不允许它
