将记录3列

Question

将记录3列基于记录计数在SQL Server

我想选择从查询的记录。我有3个栏显示记录 我已经根据计数来分割记录，那就是我需要将记录分成10行，每行有 。

此外，在我有30多个记录的事件，它需要栏，显示记录1

请参考下面的屏幕截图相连。

 
Reg SNO Reg SNO Reg SNO 
1   11   21 
2   12   22 
3     

10   20   30 

Reg SNO Reg SNO Reg SNO 
31   41   51 
32   42   52 
33     

40   50   60 

记录应该像上面给出的Excel表格一样。

我试过下面的查询在一个存储过程。但看起来像我失踪一些逻辑连接，甚至奇数的功能，我已经在where Condition.If给出了大于30的记录它不是检索作为我预期。 任何帮助将非常感激。

试试这个，在脚本中留言。

-- Create Employee table with row numbers 
IF OBJECT_ID('tempdb..#Emps') IS NOT NULL DROP TABLE #Emps 
SELECT  
    ROW_NUMBER() OVER (ORDER BY EmployeeId) 'rno' 
    , Reg 
    , SerialNo 
INTO #Emps 
FROM tRe 

CREATE CLUSTERED INDEX CIX_tempEmps_rno ON #Emps (rno) 

DECLARE @NumberOfPages INT = 50 
;WITH innerTally -- Create your numbers to fill up your first page i.e. 1 - 30

    SELECT 1 AS ID 
    UNION ALL 
    SELECT ID + 1

OPTION (MAXRECURSION 100) -- if you need more than 100 pages, you'll have to set this higher. You can set it to be the the same as @NumberOfPages (but you can't use a variable)

以下将数据分割成30行页面，然后将每个页面成10 3列...

编辑：更新以包括一个NVARCHAR数据类型列中。

IF OBJECT_ID('tempdb..#TestData', 'U') IS NOT NULL 
DROP TABLE #TestData; 

CREATE TABLE #TestData (
    ItemNo INT NOT NULL PRIMARY KEY CLUSTERED, 
    SomeString NVARCHAR(15) NOT NULL 
    ); 
INSERT #TestData (ItemNo, SomeString) 
SELECT TOP 1000 
    ROW_NUMBER() OVER (ORDER BY (SELECT NULL)), 
    CAST(ao.object_id AS NVARCHAR(15)) 
FROM 
    sys.all_objects ao; 

-- SELECT * FROM #TestData td; 

--============================================== 

WITH 
    cte_PageCol AS (
     SELECT 
      td.ItemNo, 
      PageNum = DENSE_RANK() OVER (PARTITION BY m30.Mod30 ORDER BY td.ItemNo), 
      ColumnNum = DENSE_RANK() OVER (PARTITION BY m10.Mod10 ORDER BY m30.Mod30), 
      td.SomeString 
     FROM 
      #TestData td 
      CROSS APPLY (VALUES (ISNULL(NULLIF(td.ItemNo % 30, 0), 30))) m30 (Mod30) 
      CROSS APPLY (VALUES (ISNULL(NULLIF(m30.Mod30 % 10, 0), 10))) m10 (Mod10) 
     ), 
    cte_AddRN AS (
     SELECT 
      pc.ItemNo, pc.PageNum, pc.ColumnNum, pc.SomeString, 
      RN = ROW_NUMBER() OVER (PARTITION BY pc.PageNum, pc.ColumnNum ORDER BY pc.ItemNo) 
     FROM 
      cte_PageCol pc 
     ) 
SELECT 
    ar.PageNum, 
    Col1 = MAX(CASE WHEN ar.ColumnNum = 1 THEN ar.ItemNo END), 
    Col1_Val = MAX(CASE WHEN ar.ColumnNum = 1 THEN ar.SomeString END), 
    Col2 = MAX(CASE WHEN ar.ColumnNum = 2 THEN ar.ItemNo END), 
    Col2_Val = MAX(CASE WHEN ar.ColumnNum = 2 THEN ar.SomeString END), 
    Col3 = MAX(CASE WHEN ar.ColumnNum = 3 THEN ar.ItemNo END), 
    Col3_Val = MAX(CASE WHEN ar.ColumnNum = 3 THEN ar.SomeString END) 
FROM 
    cte_AddRN ar 
GROUP BY 
    ar.PageNum, 
    ar.RN 
ORDER BY 
    ar.PageNum, 
    ar.RN; 

结果样本...
