Question

工作订单表仅显示特定工单的当前状态，每当发生更改时，wostatus表都会显示工作订单的历史记录。任何不在＆＃34;关闭＆＃34;或者＆＃34;完成＆＃34;状态被视为＆＃34;打开＆＃34;。

所以，我试图找出在特定日期有多少工作人员处于开放状态，例如2016年7月7日，同样地，每个优先级在给定范围内的开放工作人员的数量。请检查样品输出。谢谢你，非常感谢任何帮助...

Answer 1

我们必须分成几部分，我不能建议一个完整的答案，直到我知道某些部分有效。工作单表上没有关闭日期，这是一种耻辱（而且是意料之外的）。

首先要获得工作订单清单及其开启和关闭日期。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
)

我认为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。如果工单仍处于打开状态，我们将使用截止日期为2099年1月1日的

第二个查询为我们提供了我们需要报告的所有日期。再次运行并确保其有效。还请说明我们在这里报道的天数？一年？ 10？

-- 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;

让这两个查询先行，我们将从那里开始。

最后的查询将这两者结合在一起。这仍然没有完成，但会为您提供日期列表，以及在该日期仍有多少工作单仍未打开。请试试这个。如果它不起作用，我们将调试它。如果它确实有效，您必须测试您获得的数字。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

只是确认这是做什么的：对P4的数字为1,000，日期为27-08-2016意味着在此日期，在之前打开了P4的1,000个工单 on 27-08-2016，尚未关闭。因此，这是当天开放的工单的数量。这不是当天开放 ed 的数量。您不应该添加此数字，您应该在非加性趋势图中使用它

如果您想查看构成此编号的1,000个单独的工单，请使用查询1并将其添加到结尾：

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