Question

我正在尝试计算运行成本，我需要帮助一个过程，当它的值为0时，将列行值复制到下一行。这里我想将第2行的0.99复制到第3行和放大器; 4他们是0.在此之后我想向前移动0.66然后向前移动0.36。我希望这格式很好，这是我在这里的第一篇文章。谢谢你的帮助。

lngPipeRunID    lngPipeGroupID  lngInOutID  RunLoadFootage  RunFootage  RunLoadCost RunCostFoot

Answer 1

尝试以下查询

WHERE Dog_Id LIKE '%1' AND Cat_Id LIKE '%1'

Answer 2

这对我有用，有没有办法用val更新RunCostFoot？

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE spPipeRun_09_upd_RunCostFoot

AS
SET NOCOUNT ON;
BEGIN

DECLARE 

@ID INT = NULL,
@RCF MONEY = NULL

SELECT
    @ID = lngPipeRunID,
    @RCF = RunCostFoot
FROM
    tbl_Pipe_Run
WHERE
    lngPipeRunID = @ID;

WITH cte (RNO, VAL) AS
(
    SELECT lngPipeRunID AS RNO,
           RunCostFoot AS VAL
    FROM tbl_Pipe_Run
    WHERE lngPipeRunID=1
    UNION all
    SELECT RNO+1 as RNO
    ,      CASE WHEN RunCostFoot =0 then VAL
                                    else RunCostFoot end as VAL
    FROM tbl_Pipe_Run t
    join cte   ON t.lngPipeRunID=cte.RNO+1
)
SELECT *
from cte
option (maxrecursion 0)
END;
