Question

我需要按“WO＃”返回一行（VIEW_SPS_WO_OPERATION.SI_NUMBER为“WO＃”）

返回的字段在多行中显示相同的值，因此我的连接可能不正确除以下内容外：一个单独的“WO＃”可以有多个NEXT_DELIVERY_DATE “VIEW_WOBOM.NEXT_DELIVERY_DATE”，我只需要带有最新日期的条目（最大？）。

我希望我很清楚。在此先感谢您的帮助。

   SELECT 
    VIEW_SPS_WO_OPERATION.COMPANY_NAME as Customer, 
    VIEW_SPS_WO_OPERATION. SI_NUMBER as "WO #",
    VIEW_SPS_WO_OPERATION. PN as "Part Number",
    VIEW_SPS_WO_OPERATION. DEPT_NAME as "Department",
    VIEW_SPS_WO_OPERATION. TOTAL_PARTS as "Extended Price",
    VIEW_SPS_WO_OPERATION.DESCRIPTION as Description,
    VIEW_WO_SUB.WORK_TYPE as "Work Req.", 
    VIEW_SPS_WO_OPERATION.STATUS_DESC as Task, 
    VIEW_SPS_WO_OPERATION.ENTRY_DATE as "Rec Date", 
    VIEW_SPS_WO_OPERATION.DUE_DATE as "Qtd Date", 
    VIEW_SPS_WO_OPERATION.EST_COMP_DATE as "App. Date", 
    VIEW_WO_TASK_STATISTICS.SKILLS_EST_HOURS  as "Est. Labor Hrs.", 
    VIEW_WO_TASK_STATISTICS.LABOR_HOURS as "Act. Labor Hrs.",
    VIEW_WOBOM.NEXT_DELIVERY_DATE

  FROM

   WHERE 
    VIEW_SPS_WO_OPERATION.SI_NUMBER = VIEW_WO_SUB. SI_NUMBER 
     AND
    VIEW_WIP_VALUATION.WOO_AUTO_KEY = WO_BOM. WOO_AUTO_KEY AND
    VIEW_SPS_WO_OPERATION.WOO_AUTO_KEY = VIEW_WIP_VALUATION.WOO_AUTO_KEY AND
    WO_BOM.WOT_AUTO_KEY = VIEW_WO_TASK_STATISTICS.WOT_AUTO_KEY
     AND
    WO_BOM.WOT_AUTO_KEY = VIEW_WOBOM.WOT_AUTO_KEY

Answer 1

您需要MIN(VIEW_WOBOM.NEXT_DELIVERY_DATE)，并且在WHERE子句中，您需要将结果限制为VIEW_WOBOM.NEXT_DELIVERY_DATE >= Now()的结果。你如何计算NOW将取决于你的RDBMS。
