Question

我有以下查询（作为更大查询的一部分）。我试图从子查询中的2个不同的数据集中得到总和结果，但我无法将这两个数据封装成1个值。我有这个：

(Select SUM('Invoiced MTD') from 

    ((Select SUM(CASE WHEN SOH.LASDLVNUM_0 <> '' AND SOH.LASINVNUM_0 <> '' AND MONTH(SOH.SHIDAT_0) = MONTH(GETDATE()) THEN 
    (SOP.NETPRI_0 * SOQ.QTY_0 * SOH.CHGRAT_0) ELSE 0 END) as 'Invoiced MTD' 
    From x3v6.CICPROD.SORDER SOH
    LEFT OUTER JOIN x3v6.CICPROD.BPCUSTOMER BPC on SOH.BPCORD_0 = BPC.BPCNUM_0
    LEFT OUTER JOIN x3v6.CICPROD.SORDERQ SOQ on SOH.SOHNUM_0 = SOQ.SOHNUM_0
    LEFT OUTER JOIN x3v6.CICPROD.SORDERP SOP on SOQ.SOHNUM_0 = SOP.SOHNUM_0 and SOQ.SOPLIN_0 = SOP.SOPLIN_0 and SOQ.SOQSEQ_0 = SOP.SOPSEQ_0
    LEFT OUTER JOIN x3v6.CICPROD.ITMMASTER ITM on SOP.ITMREF_0 = ITM.ITMREF_0 ))

    UNION ALL

    ((Select SUM(CASE WHEN SIH.INVTYP_0 = 2 and MONTH(SIH.ACCDAT_0) = MONTH(GETDATE()) THEN SID.AMTNOTLIN_0 * (-1) ELSE 0 END) as 'Invoiced MTD'
    From x3v6.CICPROD.SINVOICE SIH 
    Left Outer Join x3v6.CICPROD.SINVOICED SID on SIH.NUM_0 = SID.NUM_0))

 as 'T2',

但是我收到UNION ALL条款的错误，我无法弄明白。基本上我想将销售贷项凭证与单独表格中的销售订单总金额合并。

有人可以帮助我吗？

这有用吗？我不确定究竟是什么导致了你的问题，但你绝对不需要这么多括号。我还建议使用格式化/美化SQL的东西。这是1）保持代码看起来一致并且2）充实语法错误的好方法。

SELECT SUM(x.invoiced_mtd)
  FROM (SELECT SUM(CASE
                     WHEN soh.lasdlvnum_0 <> '' AND soh.lasinvnum_0 <> '' AND
                          MONTH(soh.shidat_0) = MONTH(getdate()) THEN
                      (sop.netpri_0 * soq.qty_0 * soh.chgrat_0)
                     ELSE
                      0
                   END) AS invoiced_mtd
          FROM x3v6.cicprod.sorder soh
          LEFT OUTER JOIN x3v6.cicprod.bpcustomer bpc
            ON soh.bpcord_0 = bpc.bpcnum_0
          LEFT OUTER JOIN x3v6.cicprod.sorderq soq
            ON soh.sohnum_0 = soq.sohnum_0
          LEFT OUTER JOIN x3v6.cicprod.sorderp sop
            ON soq.sohnum_0 = sop.sohnum_0
           AND soq.soplin_0 = sop.soplin_0
           AND soq.soqseq_0 = sop.sopseq_0
          LEFT OUTER JOIN x3v6.cicprod.itmmaster itm
            ON sop.itmref_0 = itm.itmref_0
        UNION ALL
        SELECT SUM(CASE
                     WHEN sih.invtyp_0 = 2 AND
                          MONTH(sih.accdat_0) = MONTH(getdate()) THEN
                      sid.amtnotlin_0 * (-1)
                     ELSE
                      0
                   END)
          FROM x3v6.cicprod.sinvoice sih
          LEFT OUTER JOIN x3v6.cicprod.sinvoiced sid
            ON sih.num_0 = sid.num_0) x;

Answer 2

这个怎么样？

Select SUM([Invoiced MTD]) from
(  
  Select SUM(CASE WHEN SOH.LASDLVNUM_0 <> '' AND SOH.LASINVNUM_0 <> '' AND MONTH(SOH.SHIDAT_0) = MONTH(GETDATE()) 
                   THEN (SOP.NETPRI_0 * SOQ.QTY_0 * SOH.CHGRAT_0) ELSE 0 END) as 'Invoiced MTD' 
   From x3v6.CICPROD.SORDER SOH
   LEFT OUTER JOIN x3v6.CICPROD.BPCUSTOMER BPC on SOH.BPCORD_0 = BPC.BPCNUM_0
   LEFT OUTER JOIN x3v6.CICPROD.SORDERQ SOQ on SOH.SOHNUM_0 = SOQ.SOHNUM_0
   LEFT OUTER JOIN x3v6.CICPROD.SORDERP SOP on SOQ.SOHNUM_0 = SOP.SOHNUM_0 and SOQ.SOPLIN_0 = SOP.SOPLIN_0 and SOQ.SOQSEQ_0 = SOP.SOPSEQ_0
   LEFT OUTER JOIN x3v6.CICPROD.ITMMASTER ITM on SOP.ITMREF_0 = ITM.ITMREF_0 

UNION ALL
   Select SUM(CASE WHEN SIH.INVTYP_0 = 2 and MONTH(SIH.ACCDAT_0) = MONTH(GETDATE()) 
                THEN SID.AMTNOTLIN_0 * (-1) ELSE 0 END) as 'Invoiced MTD'
   From x3v6.CICPROD.SINVOICE SIH 
   Left Outer Join x3v6.CICPROD.SINVOICED SID on SIH.NUM_0 = SID.NUM_0
)T

Answer 3

首先尝试使用CTE进行UNION查询。以下是与查询结构相同的简化示例：

;with cteTest AS (

    ((select 2 as 'test'))
    union all
    ((select 3 as 'test'))

)

select sum(test) from cteTest

使用UNION ALL子句将两个单独的查询合并为一个值
