Oracle SQL組無法正常工作

Question

我正在運行一個查詢，以返回每周完成的工作數量的計數，並且根據單獨的財務周期表將周細分為4個每周的周期，但是查詢未返回正確的計數。

這是代碼示例：

select (SELECT (fp.financialperiod || ' week ' ||
ceil(floor((wo.actfinish - p.periodstart+1))/7))
        FROM maximo.financialperiods fp
       WHERE TRUNC (wo.actfinish) BETWEEN fp.periodstart
                                      AND fp.periodend) fin_period,
wo.wo8 as assetgroup,
Count(wo.wonum)
from maximo.workorder wo
where (TRUNC (wo.actfinish) BETWEEN TO_DATE (:startdate, 'DD/MM/YYYY')
                                    AND TO_DATE (:enddate, 'DD/MM/YYYY'))
group by wo.actfinish,
wo.wo8

Answer 1

SELECT 
    (SELECT (fp.financialperiod || ' week ' || ceil(floor((wo.actfinish - p.periodstart+1))/7))
     FROM maximo.financialperiods fp
     WHERE TRUNC (wo.actfinish) BETWEEN fp.periodstart AND fp.periodend) fin_period, wo.wo8 as assetgroup, Count(wo.wonum) AS [Count]
FROM maximo.workorder wo
WHERE (TRUNC (wo.actfinish) BETWEEN TO_DATE (:startdate, 'DD/MM/YYYY')
                                    AND TO_DATE (:enddate, 'DD/MM/YYYY'))
GROUP BY wo.actfinish, wo.wo8, fp.financialperiod

Answer 2

我懷疑原因是您需要按第一列進行匯總。 根據查詢的結構，最簡單的方法是使用子查詢：

select fin_period, wo.wo8, count(wo.wonum) as cnt
from (select (SELECT (fp.financialperiod || ' week ' || ceil(floor((wo.actfinish -    p.periodstart+1))/7))
              FROM maximo.financialperiods fp
              WHERE TRUNC (wo.actfinish) BETWEEN fp.periodstart AND fp.periodend
             ) as fin_period,
             wo.wo8 as assetgroup, wo.wonum
      from maximo.workorder wo
      where TRUNC(wo.actfinish) BETWEEN TO_DATE (:startdate, 'DD/MM/YYYY')
                                    AND TO_DATE (:enddate, 'DD/MM/YYYY')
     ) t
group by fin_period, wo.wo8;
