Question

美好的一天，我很抱歉我的头衔。好的，举个例子我有这个数据

OutletAsal  OutletTujuan    remark  ExternalDocNo   ItemCode    Qty
K-AEON        K-AR4         DUS 20  CLOSING       WFS170402776  2
K-AEON        K-AR4         DUS 20  CLOSING       WFS170402758  1
K-AEON        K-AR4         DUS 20  CLOSING       WFS170402790  1
K-AEON        K-AR4         DUS 20  CLOSING       WFS170502796  2
K-AEON        K-AR4         DUS 20  CLOSING       WHS170400011  1
K-AEON        K-AR4         DUS 20  CLOSING       WHS170400015  1
K-AEON        K-AR4         DUS 21  CLOSING       WHS170400015  1

所以，我想实现这个目标（Grouping OutletAsal，OutletTujuan，Remark，ExtrnalDocNo最多5条记录，如果有6条记录则会产生2条标题）

#Header
OutletAsal  OutletTujuan    remark  ExternalDocNo HeaderID
K-AEON        K-AR4         DUS 20  CLOSING         1
K-AEON        K-AR4         DUS 20  CLOSING         2
K-AEON        K-AR4         DUS 21  CLOSING         3

#detail
     ItemCode     Qty  HeaderID
    WFS170402776   2     1
    WFS170402758   1     1
    WFS170402790   1     1
    WFS170502796   2     1
    WHS170400011   1     1
    WHS170400015   1     2
    WHS170400015   1     3

现在我有header部分

的查询

SELECT LTRIM(RTRIM(OutletAsal)) OutletAsal,LTRIM(RTRIM(OutletTujuan)) OutletTujuan,Remark,
ROW_NUMBER() OVER(ORDER BY OutletAsal,OutletTujuan,Remark ASC) AS Urut
into #tempgroup
FROM ImportCsvDO
GROUP BY OutletAsal ,OutletTujuan , Remark ,ExternalDocNo

根据我上面的查询我得到了这个并不像我预期的那样（请在上面查看）

OutletAsal  OutletTujuan    Remark  Urut
K-AEON       K-AR4           DUS 20 1
K-AEON       K-AR4           DUS 21 2

提前致谢，抱歉我的英语不好。

您可以在SQl中使用modulo (%)，就像这样

;with temp AS
(
    SELECT *,
         row_number() OVER(PARTITION BY OutletAsal ,OutletTujuan , Remark ,ExternalDocNo ORDER BY ic.Id) AS Rn
    FROM ImportCsvDO ic
)
SELECT  OutletAsal,
       OutletTujuan,
       Remark,
       ExternalDocNo,
       ROW_NUMBER() OVER(ORDER BY OutletAsal,OutletTujuan,Remark ASC) AS HeaderId,
       t.Rn as GroupHeaderId 
FROM temp t
WHERE t.Rn % 5 = 1

详细表格（假设您有标题表）

;with temp AS
(
    SELECT *,
         row_number() OVER(PARTITION BY OutletAsal ,OutletTujuan , Remark ,ExternalDocNo ORDER BY ic.Id) AS Rn
    FROM @SampleData ic
)
SELECT t.ItemCode,
      Qty,       
      ht.HeaderId AS HeaderID
FROM temp t
INNER JOIN @HeaderTable ht ON     t.OutletAsal = ht.OutletAsal
                          AND t.OutletTujuan = ht.OutletTujuan
                          AND t.Remark = ht.remark
                          AND t.ExternalDocNo = ht.ExternalDocNo
                          AND (t.Rn - 1) / 5 = (ht.GroupHeaderId - 1) / 5
