sql - SQL 与 sum 连接

Question

您好，我有以下 SQL 查询，它产生以下结果

SELECT * FROM
     (
     Select
        catalogid, numitems, allitems - numitems ignoreditems
     from
         ( 
             select
                 i.catalogid,
                 case
                     when Exists(select paymentodate from payentmethodvalidation q where q.paymentnoodate = o.ocardtype) AND NOT EXISTS(SELECT booked FROM bookedordersids m where CAST(m.booked AS int)=o.orderid) then sum(i.numitems)
                     when Exists(select paymentodate from payentmethodvalidation q where q.paymentodate = o.ocardtype) AND odate is not null AND NOT EXISTS(SELECT booked FROM bookedordersids m where CAST(m.booked AS int)=o.orderid) then sum(i.numitems)
                 else 0 end numitems,
                 sum(numitems) allitems 
             from 
                 "orders o
             inner join
                 "oitems i 
             on 
                 "i.orderid=o.orderid
             inner join
                 "products T1
             on 
                 "T1.catalogid = i.catalogid
             group by 
                 "i.catalogid, ocardtype, odate,o.orderid
         ) A
     ) B
     INNER JOIN
     (
         SELECT 
             catalogId, 
             ProcessedSucssessfully = 
                STUFF((SELECT ', ' + CAST( b.orderid as varchar(10))
                       FROM oitems b JOIN orders o ON b.orderid = o.orderid 
                       WHERE b.catalogId = a.catalogId 
                       AND  NOT EXISTS(SELECT booked FROM bookedordersids m where CAST(m.booked AS int)=o.orderid) AND (Exists(select paymentodate from payentmethodvalidation q where q.paymentnoodate = o.ocardtype) OR Exists(select paymentodate from payentmethodvalidation q where q.paymentodate = o.ocardtype) and o.odate is not null)
                       FOR XML PATH('')), 1, 2, ''), 
                           "NotProcessed = 
                 STUFF((SELECT ', ' + CAST( c.orderid as varchar(10))
                        FROM oitems c JOIN orders o ON c.orderId = o.orderid
                        WHERE c.catalogid = a.catalogid 
                        AND (o.ocardtype in ('mastercard') OR o.ocardtype is null) and o.odate is null
                        FOR XML PATH('')), 1, 2, '') 
         FROM 
             oitems a 
         GROUP BY 
             a.catalogid 
     )C
         ON 
             B.catalogid = C.catalogid 

您可以在下图中看到此查询的结果

您会看到那 2 个带圆圈的行，我希望它们位于一行中，仅对 numitems 进行求和，处理成功的值和所有其他值对于共享目录 ID 的记录将始终相同，因此它们没有问题。

基本上，结果行应该具有所有具有相同目录 ID 的行中的 numitem 值的总和

那么我该如何解决这个问题呢？

Answer 1

如果，正如您所提到的，所有其余的值都相同，则解决方案很简单：

SELECT CATALOGID, 
       Sum(NUMITEMS), 
       ALLITEMS - NUMITEMS ignoreditems 
FROM   (SELECT CATALOGID, 
               NUMITEMS, 
               ALLITEMS - NUMITEMS ignoreditems

                       CASE 
                         WHEN EXISTS(SELECT PAYMENTODATE

                              AND NOT EXISTS(SELECT BOOKED
