Interbase SQL 重做一个 Select 查询

Question

我需要你的帮助。

我有一个 Interbase SQL Select 查询：

选择 aps.fullname, aps.productvcode, aps.alccode, aps.capacity, Cast(Round(Sum(当 wp.capacity>0 时的情况然后 wp.quantity * wp.capacity/10 否则 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' 按 aps.fullname 分组， aps.productvcode、aps.alccode、aps.capacity
联合所有
选择 aps.fullname、aps.productvcode、aps.alccode、aps.capacity、 Cast(Round(Sum(当 wp.capacity>0 然后 wp.quantity * wp.capacity/10 时的情况 否则 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 其中 wp.alccode='0001821000001389010' 按 aps.fullname 分组， aps.productvcode, aps.alccode, aps.capacity

它给了我这个：

但我希望第二行中的值 "156,9750" 成为 "WBTOTAL" 右侧的单独列，并具有标题 "WBOTOTAL"

怎么做？

您可以使用 CTE，如下所示

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
