Question

我有一个场景，我们有两个系统都包含相关的PO - 一个是全局系统，一个是本地系统。我需要编写2个显示1的查询：在全局系统中取消但在本地系统中没有取消2.在本地系统中取消但在全局系统中取消。棘手的部分是全局系统将始终只有1个行项目，其状态为90表示取消或10表示活动。本地端的相关采购订单可以有多个行项目，如果其中任何一个处于活动状态，则采购订单处于活动状态。我为第一个场景编写了下面的SQL，它运行得很好，因为如果本地端的任何单个PO行项目处于活动状态，则PO处于活动状态。现在我需要做相反的事情而且我遇到了麻烦，因为我不知道如何说“只有当所有线路都关闭时，PO才会关闭” - 任何想法。欣赏帮助，仍然学习如何使用标签。本地“L”是行的代码被删除 - 空白将被激活。

第一个有效的场景的查询是：

SELECT G.order_no AS 'GPS_ORDER_#', 
       G.order_status AS 'GPS_ORDER_STATUS', 
       G.cst_order_no AS 'GPS_CUSTOMER_PO_#',
       H.PO_NUMBER AS 'SAP_PO_#',
       P.PO_ITEM_NUMBER, 
       P.DEL_INDICATOR
  FROM (SELECT order_no, 
               order_status, 
               cst_order_no
          FROM asagdwpdx_prod.dbo.SimoxOrder1
         UNION ALL
        SELECT order_no, 
               order_status, 
               cst_order_no
          FROM asagdwpdx_prod.dbo.SimoxOrder2
         UNION ALL 
        SELECT order_no, 
               order_status, 
               cst_order_no
          FROM asagdwpdx_prod.dbo.SimoxOrder3) G 
  JOIN PDX_SAP_USER.dbo.VW_PO_HEADER H 
    ON G.order_no = H.AHAG_NUMBER
  JOIN PDX_SAP_USER.dbo.VW_PO_ITEM P 
    ON H.PO_NUMBER = P.PO_NUMBER 
 WHERE G.order_status = '90'
   AND   P.DEL_INDICATOR <> 'L';

Answer 1

第1步：

SELECT ... CASE WHEN DEL_INDICATOR = 'L' THEN TRUE ELSE FALSE END AS DEL_INDICATOR_BOOL

第2步：

... GROUP BY P.PO_NUMBER HAVING BOOL_AND(DEL_INDICATOR_BOOL) == FALSE

用文字说明：

可以使用group by + having + aggregate function

Answer 2

如果全局采购订单始终至少有1个匹配的本地采购订单，那么您可以在状态为活动状态的本地采购订单上执行子查询并加入，然后查找本地采购订单的空值。如果没有评论，我将不会尝试更改您的查询，但它看起来像是：

SELECT
    global_table.po
FROM global_table
LEFT JOIN (
    SELECT
        PO
    FROM local_table
    WHERE local_table.po_status = 90    --Looking for any active POs
    ) AS local_table ON
    global_table.po = local_table.po    --Join those active POs
WHERE local_table.po IS NULL    --Exclude any POs that had an active record in the local table

如果使用以下查询中的CASE语句全部为“L”，则检查del_indicator的值

SELECT g.order_no AS 'gps_order_#', 
       g.order_status AS 'gps_order_status', 
       g.cst_order_no AS 'gps_customer_po_#',
       l.po_number AS 'sap_po_#',
       l.po_item_number, 
       l.del_indicator
  FROM (SELECT order_no, 
               order_status, 
               cst_order_no
          FROM asagdwpdx_prod.dbo.simoxorder1
         UNION ALL
        SELECT order_no, 
               order_status, 
               cst_order_no
          FROM asagdwpdx_prod.dbo.simoxorder2
         UNION ALL 
        SELECT order_no, 
               order_status, 
               cst_order_no
          FROM asagdwpdx_prod.dbo.simoxorder3) g
  JOIN (SELECT h.ahag_number,
               h.po_number,
               i.po_item_number, 
               i.del_indicator,
               CASE WHEN MIN(i.del_indicator) = MAX(i.del_indicator) 
                     AND MIN(i.del_indicator) = 'L'
                    THEN 'closed'
                    ELSE 'active'
                END local_o_status
          FROM pdx_sap_user.dbo.vw_po_header h
          JOIN pdx_sap_user.dbo.vw_po_item i
            ON h.po_number = i.po_number
         GROUP BY h.ahag_number,
                  h.po_number,
                  i.po_item_number, 
                  i.del_indicator) l
    ON g.order_no = l.ahag_number
 WHERE g.order_status = '10'
   AND l.local_o_status = 'closed'

如何使用SQL Server基于多个订单项的组合排除整个采购订单？
