如何获取日期范围内未结工作订单的数量

Question

工作订单表仅显示特定工作订单的当前状态，每当发生更改时，wostatus 表都有工作订单的历史记录。任何未处于“关闭”或“完成”状态的工作订单都被视为“打开” ”。

所以，我试图找出在特定日期（例如 2016 年 7 月 7 日）有多少工作订单处于打开状态，同样，每个优先级的给定范围内打开工作订单的数量。请检查示例输出。谢谢你，任何帮助都非常感谢......

Answer 1

我们必须分批进行，在我知道某些部分有效之前，我无法给出完整的答案。工单表上没有截止日期，这很遗憾（而且出乎意料）。

首先是获取工作订单列表及其开始和结束日期。试试这个查询，看看它是否有效

-- Query 1: Get a list of work order with open and close dates
-- excluding WO's that were already closed before 1 Jan 2016

SELECT 
WO.WONum, 
WO.OpenDate, 
ISNULL(
    WC.CloseDate,
    CONVERT(DATE,'20990101',112)
) as CloseDate
FROM WorKOrder WO
LEFT OUTER JOIN 
(
SELECT WONum, MAX(ChangeDate) as CloseDate
FROM WorKOrder
WHERE Status IN ('Close','Complete')
GROUP BY WONum
) WC
ON WO.WONum = WC.WONum
-- Exclude altogether any work orders that were closed prior to 1 Jan 2016
-- As these should not appear in the report
WHERE NOT EXISTS (
    SELECT *
    FROM WorKOrder WAC
    WHERE Status IN ('Close','Complete')
    AND ChangeDate <= CONVERT(DATE,'20160101',112)
    AND WAC.WONum = WO.WONum
)

我假设WONum 在表WorkOrder 上是唯一的？此查询应列出所有工作订单及其打开和关闭日期。如果工作订单当前仍处于打开状态，我们将使用 2099 年 1 月 1 日的结束日期

第二个查询为我们提供了需要报告的所有日期。再次运行并确保它有效。另外请澄清我们在这里报告了多少天？一年？十个？

-- Query 2: Tally/calendar table
;WITH
TENS (N)      AS (SELECT 0 UNION ALL SELECT 0 UNION ALL
                  SELECT 0 UNION ALL SELECT 0 UNION ALL
                  SELECT 0 UNION ALL SELECT 0 UNION ALL
                  SELECT 0 UNION ALL SELECT 0 UNION ALL
                  SELECT 0 UNION ALL SELECT 0),
THOUSANDS (N) AS (SELECT 1
                    FROM TENS t1
                         CROSS JOIN TENS t2
                         CROSS JOIN TENS t3),
TALLY (N)     AS (SELECT ROW_NUMBER() OVER (ORDER BY (SELECT 0))
                    FROM THOUSANDS)
SELECT TOP 1000 DATEADD(d,N,CONVERT(DATE,'20151231',112)) ADate
FROM TALLY;

让这两个查询首先工作，然后我们将从那里开始。

最后的查询将这两者结合在一起。这还没有完成，但会为您提供日期列表，以及在该日期仍有多少工作订单处于打开状态。请试试这个。如果它不起作用，我们将对其进行调试。如果它确实有效，你必须测试你得到的数字。然后我们将添加P分解

-- Query 3: stick it all together
;WITH
TENS (N)      AS (SELECT 0 UNION ALL SELECT 0 UNION ALL
                  SELECT 0 UNION ALL SELECT 0 UNION ALL
                  SELECT 0 UNION ALL SELECT 0 UNION ALL
                  SELECT 0 UNION ALL SELECT 0 UNION ALL
                  SELECT 0 UNION ALL SELECT 0),
THOUSANDS (N) AS (SELECT 1
                    FROM TENS t1
                         CROSS JOIN TENS t2
                         CROSS JOIN TENS t3),
TALLY (N)     AS (SELECT ROW_NUMBER() OVER (ORDER BY (SELECT 0))
                    FROM THOUSANDS)

SELECT 
WO.Priority,
CAL.D As IsOpenDate,
COUNT(*)
FROM WorKOrder WO
LEFT OUTER JOIN 
(
SELECT WONum, MAX(ChangeDate) as CloseDate
FROM WorKOrder
WHERE Status IN ('Close','Complete')
GROUP BY WONum
) WC
ON WO.WONum = WC.WONum
INNER JOIN 
(SELECT DATEADD(d,N,CONVERT(DATE,'20160101',112)) D FROM TALLY) CAL
ON CAL.D BETWEEN WO.OpenDate 
   AND   ISNULL(
            WC.CloseDate,
            CONVERT(DATE,'20990101',112)
         )
WHERE NOT EXISTS (
    SELECT *
    FROM WorKOrder WAC
    WHERE Status IN ('Close','Complete')
    AND ChangeDate <= CONVERT(DATE,'20160101',112)
    AND WAC.WONum = WO.WONum
)
GROUP BY CAL.D, WO.Priority

只需确认这是做什么的：针对 P4 的 1,000 个数字和 2016 年 8 月 27 日的日期意味着在该日期，P4 有 1,000 个工作订单在之前打开或于 2016 年 8 月 27 日，尚未关闭。所以这是当天有多少工作订单打开的计数。这不是当天打开ed的数量。你不应该把这个数字加起来，你应该在非加法趋势图中使用它

如果您想查看构成此编号的 1,000 个单独的工作订单，请使用查询 1 并将其添加到末尾：

AND CONVERT(DATE,'20160827',112) BETWEEN WO.OpenDate 
       AND   ISNULL(
                WC.CloseDate,
                CONVERT(DATE,'20990101',112)
             )
