如何做到这一点？

Question

有以下数据

格式如下

CREATE TABLE [dbo].[Sample](
    [CCMPNY] [varchar](2) NOT NULL,
    [CCUST#] [numeric](7, 0) NOT NULL,
    [RDDYSR] [varchar](7) NOT NULL,
    [CBLNAM] [varchar](30) NOT NULL,
    [CCYCLE] [varchar](2) NOT NULL,
    [RDSIZE] [varchar](2) NOT NULL,
    [RDCHGC] [varchar](2) NOT NULL,
    [RDDAY] [numeric](1, 0) NOT NULL,
    [RDROUT] [varchar](4) NOT NULL,
    [RDQTY] [numeric](5, 0) NOT NULL

我怎样才能得到下面的布局

标记为红色的列

FREQ: "Count" of Days in "RDDYSR" field
LIFTS: "Lifts" = "RDQTY" times "Freq"
VOLUME: "Volume" = "RDQTY" times "RDSIZE" times "Freq"

Week Days columns: 
MON: If "RDDYSR" includes "M", "RDQTY" times "RDSIZE", else "blank".  
TUE: If "RDDYSR" includes "T", "RDQTY" times "RDSIZE", else "blank", etc.

注释

that each "CCUST" generates only one data line unless 
(1) there are multiple "RDCHGC" values (CCUST 43), 
(2) there are multiple "RDSIZE" values (CCUST 10723); or, 
(3) there are multiple "FREQ" values (no example).

感谢您的帮助。

试试这个查询，

SELECT CCUST
,CBLNAM
,RDCHGC
,RDQTY
,RDSIZE
,LEN(REPLACE(RDDYSR,'-','')) AS FREQ
,COUNT(RDDYSR)*RDQTY AS LIFTS
,RDSIZE * RDQTY * LEN(REPLACE(RDDYSR,'-','')) AS VOLUME
,FIRSTRDDYSR AS RDDYSR,FIRSTRDROUT AS RDROUT
,CASE WHEN (FIRSTRDDYSR LIKE 'M______') THEN RDQTY * RDSIZE END AS MON 
,CASE WHEN (FIRSTRDDYSR LIKE '_T_____') THEN RDQTY * RDSIZE END AS TUE
,CASE WHEN (FIRSTRDDYSR LIKE '__W____') THEN RDQTY * RDSIZE END AS WED
,CASE WHEN (FIRSTRDDYSR LIKE '___H___') THEN RDQTY * RDSIZE END AS THU
,CASE WHEN (FIRSTRDDYSR LIKE '____F__') THEN RDQTY * RDSIZE END AS FRI
,CASE WHEN (FIRSTRDDYSR LIKE '_____S_') THEN RDQTY * RDSIZE END AS SAT
FROM
(
    SELECT S.*, T.RDROUT AS FIRSTRDROUT, T.RDDYSR AS FIRSTRDDYSR FROM
    [SAMPLE] S
    INNER JOIN
    (
        SELECT CCUST, RDROUT, RDDYSR, ROW_NUMBER() OVER(PARTITION BY ccust ORDER BY (SELECT 1)) N
        FROM SAMPLE
    ) T ON S.CCUST = T.CCUST AND N = 1
) Tbl

GROUP BY CCUST, CBLNAM, RDCHGC, RDQTY, RDSIZE, RDDYSR, FIRSTRDDYSR, FIRSTRDROUT

这应该会稍微简单地为您提供您正在寻找的内容。我不确定你星期天的标识符是什么，所以我用 --

注释掉了它

select CCUST# CCUST, CBLNAM,RDCHGC, RDQTY, RDSIZE, Len(Replace(RDDYSR, '-', '')) FREQ, 
RDQTY * Len(Replace(RDDYSR, '-', '')) LIFTS, 
RDQTY * Cast(RDSIZE as int) * Len(Replace(RDDYSR, '-', '')) Volume, RDDYSR,
Case when CHARINDEX('M', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Mon,
Case when CHARINDEX('T', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Tue,
Case when CHARINDEX('W', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Wed,
Case when CHARINDEX('H', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Thu,
Case when CHARINDEX('F', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Fri,
Case when CHARINDEX('S', RDDYSR) > 0 then RDQTY * Cast(RDSIZE as int) end as Sat
--,Case when CHARINDEX(RDDYSR, 'X') > 0 then RDQTY * Cast(RDSIZE as int) end as Sun   --Whatever Sunday identifier is

from Sample

Group by CCUST#, CBLNAM, RDCHGC, RDQTY, RDSIZE, RDDYSR
