在SSRS报表中显示三张表的记录，每张表的行数都不一样

Question

我有一个报表中的表，像

我想在每个页面上显示三个表中的记录，每个表中只包含20条记录。

第1页。

Page2:

如何实现这种模式？

Answer 1

我想到了2种方式，一种是MATRIX风格的报表，其中列组是你的列，另一种是普通的表，你把数据JOIN出来3份，分别是姓名、ID和其他你想要的字段。MATRIX风格无疑是更优雅和灵活的，但如果你要把报表交给高级用户，普通表可能更容易被客户修改。

这两种解决方案都是先用PAGE、ROW和COLUMN信息标记数据。请注意，我是按NAME排序的，但你可以按任何字段排序。还要注意的是，这个解决方案并不依赖于你的ID是顺序的，也不依赖于你想要的顺序，它根据NAME或你选择的任何其他内容生成自己的顺序号。

在这个演示中，我将RowsPerPage和NumberofColumns设置为硬编码常数，但如果你使用MATRIX格式，它们可以很容易地成为用户选择的参数。

DECLARE @RowsPerPage INT = 20
DECLARE @Cols INT = 3

;with 
--Fake data generation BEGIN
cteSampleSize as (SELECT TOP 70 ROW_NUMBER () OVER (ORDER BY O.name) as ID 
    FROM sys.objects as O
), cteFakeData as (
    SELECT N.ID, CONCAT(CHAR(65 + N.ID / 26), CHAR(65 + ((N.ID -1) % 26))
        --, CHAR(65 + ((N.ID ) % 26))
        ) as Name
    FROM cteSampleSize as N
), 
--Fake data generation END, real processing begins below
cteNumbered as ( -- We can't count on ID being sequential and in the order we want!
    SELECT D.*, ROW_NUMBER () OVER (ORDER BY D.Name) as SeqNum
        --Replace ORDER BY D.Name with ORDER BY D.{Whatever field}
    FROM cteFakeData as D --Replace cteFakeData with your real data source
), ctePaged as (
    SELECT D.*
        , 1+ FLOOR((D.SeqNum -1) / (@RowsPerPage*@Cols)) as PageNum
        , 1+ ((D.SeqNum -1) % @RowsPerPage) as RowNum
        , 1+ FLOOR(((D.SeqNum-1) % (@RowsPerPage*@Cols) ) / @RowsPerPage) as ColNum
    FROM cteNumbered as D
) 
--FINAL - use this for MATRIX reports (best)
SELECT * FROM ctePaged ORDER BY SeqNum

如果你想在普通的表中使用JOIN方法来允许这样做，用这个查询代替上面的--FINAL查询。需要注意的是，这是很细微的，所以在最终的报告中用几度的满度来测试。我用70行和90行的样本数据进行了测试，所以我有部分第一列和完整的第一列和部分第二列。

--FINAL - use this for TABLE reports (simpler)
SELECT C1.PageNum , C1.RowNum , C1.ID as C1_ID, C1.Name as C1_Name
    , C2.ID as C2_ID, C2.Name as C2_Name
    , C3.ID as C3_ID, C3.Name as C3_Name
FROM ctePaged as C1 LEFT OUTER JOIN ctePaged as C2 
        ON C1.PageNum = C2.PageNum AND C1.RowNum = C2.RowNum 
            AND C1.ColNum = 1 AND (C2.ColNum = 2 OR C2.ColNum IS NULL)
    LEFT OUTER JOIN ctePaged as C3 ON C1.PageNum = C3.PageNum 
        AND C1.RowNum = C3.RowNum AND (C3.ColNum = 3 OR C3.ColNum IS NULL)
WHERE C1.ColNum = 1

1）用下面的查询添加数据集，得到Page号和Table号。你可以根据需要改变20和60的数量。在我的例子中，我需要每节20条记录，有3个节，所以每页总记录数为60条。

Select *,(ROW_NUMBER ( ) OVER ( partition by PageNumber order by Id )-1)/20 AS TableNumber   from (
Select (ROW_NUMBER ( ) OVER (  order by Id )-1)/60 AS PageNumber
,* from Numbers
)Src

2)添加一列表，选择准备好的数据集。
