Interbase SQL重做一個Select查詢

Question

我需要你幫忙。

我有一個Interbase的SQL SELECT查詢：

選擇aps.fullname，aps.productvcode，aps.alccode，aps.capacity，CAST（圓（總和（情況下wp.capacity> 0，則WP .quantity * wp.capacity/10 else wp.quantity * wp.capacity end），4）as DECIMAL（18,4））as WBTotal from AP aps left加入Waybill_positions wp on wp.alccode = aps.alccode其中 wp.​​alccode = '0001821000001389010' 由aps.fullname， aps.productvcode，aps.alccode組，aps.capacity
UNION ALL
選擇aps.fullname ，aps.productvcode，aps.alccode，aps.capacity， Cast（Round（Sum（wp.capacity> 0 then wp.quantity * wp.capacity/10 else wp.quantity * wp.capacity end），4 ）as DECIMAL（18,4））as WBTotal from AP aps left加入Waybill_out_positions wp on wp.alccode = aps.alccode 其中wp.alccode ='0001821000001389010'group by aps.fullname， aps.productvcode，aps.alccode ，aps.capacity

，這讓我這個：

但我想從第二行的值「156,9750」是右邊一個單獨的列旁邊「WBTOTAL」，並有標題「WBOTOTAL」

怎麼辦呢？

您可以使用CTE，像下面

with CTE1 as 
(
    Select aps.fullname, aps.productvcode, aps.alccode, aps.capacity, Cast(Round(Sum(case when wp.capacity>0 then wp.quantity * wp.capacity/10 else wp.quantity * wp.capacity end),4) as DECIMAL(18,4)) as WBTotal from AP aps left join Waybill_positions wp on wp.alccode=aps.alccode where wp.alccode='0001821000001389010' group by aps.fullname, aps.productvcode, aps.alccode, aps.capacity 
), 
CTE2 as 
(
    Select aps.fullname, aps.productvcode, aps.alccode, aps.capacity, Cast(Round(Sum(case when wp.capacity>0 then wp.quantity * wp.capacity/10 else wp.quantity * wp.capacity end),4) as DECIMAL(18,4)) as WBTotal from AP aps left join Waybill_out_positions wp on wp.alccode=aps.alccode where wp.alccode='0001821000001389010' group by aps.fullname, aps.productvcode, aps.alccode, aps.capacity 
) 
Select CTE1.fullname, CTE1.productvcode, CTE1.alccode, CTE1.capacity, CTE1.WBTotal, CTE2.WBTotal as WBOTOTAL 
From CTE1 
join CTE2 
on CTE1.productvcode = CTE2.productvcode 
and CTE1.alccode = CTE2.alccode
