Question

是否可以在sql中创建：

拥有记录表：

    ID      LaborID     OrderNr      OrderStatusID  OrderStatusDate

，其中

OrderStatusID   
0 - End
1 - Begin
2 - pause

需要计算工作时间from begin to pause (1->2)或from begin to end (1->0)。我的问题是我必须遵守一些条件：

如果第一条记录为2，则忽略

工作始于1

但可以有更多停顿(1->2) 每次使用0

的最后一份工作结束记录

这种情况下的结果将是：

OPT1814378          230687389   00:20:00      
OPT1814378          230480202   00:11:12   
OPT1814089          10138504    00:16:12
OPT1814089          10138504    00:34:00

Answer 1

希望这不是那么难看。

gluster-heketi

; with cte as ( -- CTE for generating a sequence no select *, rn = row_number() over (partition by OrderNr order by OrderStatusDate) from @table ), cte2 as ( -- Clean up invalid any rows and regenerate new sequence no select ID, LaborID, OrderNr, OrderStatusID, OrderStatusDate, rn = row_number() over (partition by OrderNr order by OrderStatusDate) from cte where (rn = 1 and OrderStatusID = 1) or rn >= 2 ) select OrderNr, LaborID, convert(varchar(10), dateadd(second, datediff(second, min(OrderStatusDate), max(OrderStatusDate)), 0), 108) from cte2 group by OrderNr, LaborID, (rn - 1) / 2将给出值0,0,1,1,2,2等，用于将行逐个分组。

Answer 2

这个也有效

;WITH CTE
AS ( 
    SELECT row_number() OVER ( PARTITION BY ordernr ORDER BY id ) RN ,* FROM test_ti 
    )

,cte2
AS (
    SELECT *
    FROM cte c1
    WHERE NOT EXISTS (
            SELECT *
            FROM cte c2
            WHERE c1.id = c2.id
                AND c2.rn = 1
                AND c2.orderstatusid = 2
            )
    )
SELECT OrderNr
    ,LaborId
    ,TimeInterval
FROM ( SELECT DateDiff(MI, TIME, NxtTm) TimeInterval ,*
    FROM (
        SELECT * ,lead(TIME) OVER ( ORDER BY id ) NxtTm
        FROM cte2
        ) x
    WHERE orderstatusid <> 0
    ) y
WHERE orderstatusid = 1
