Question

我正在尝试构建将返回Crystal Reports报表数据的存储过程。在CR内部我使用多列布局。

我希望获得3个布局列：

 1    5   8
 2    6   9
 3    7   10
 4

但是因为CR有一些布局问题，所以我这样订购我的表：

所以我试图创建一个程序，它将返回我将对数据进行排序的额外列。

所以相反1,2,3,4顺序我需要1,4,7,10,2,5,8,3,6,9 ...

我有数据表：

ID | CASE_ID |  CASE_DATE
--------------------------
 1 |   1     | 2014-02-03
 2 |   1     | 2014-02-04
 3 |   1     | 2014-02-05
 4 |   1     | 2014-02-06
 5 |   1     | 2014-02-07
 6 |   1     | 2014-02-08
 7 |   1     | 2014-02-09
 8 |   1     | 2014-02-10
 9 |   1     | 2014-02-11
10 |   1     | 2014-02-12

我需要存储过程来返回这些数据：

ID | CASE_ID |  CASE_DATE | ORDER
---------------------------------
 1 |   1     | 2014-02-03 |    1
 2 |   1     | 2014-02-04 |    5
 3 |   1     | 2014-02-05 |    8
 4 |   1     | 2014-02-06 |    2
 5 |   1     | 2014-02-07 |    6
 6 |   1     | 2014-02-08 |    9
 7 |   1     | 2014-02-09 |    3
 8 |   1     | 2014-02-10 |    7
 9 |   1     | 2014-02-11 |    10
10 |   1     | 2014-02-12 |    4

以下是sql中包含示例数据和我的代码：http://sqlfiddle.com/#!3/c24c1/1

排序列背后的想法：

将所有行划分为3组（ntile），从第一组中获取第一项，然后从第二组中获取第一项，从第三组中获取第一项

修改这是我的临时解决方案，我希望运行此解决方案可以澄清我在提出这个问题时的想法：

--DECLARE @NUM INT;
--SET @NUM=3;

SELECT ID,
       CASE_ID,
       CONVERT(NVARCHAR(10),CASE_DATE,121) AS DATA,
       (ROW1 - 1) * 3/*@NUM*/ + COL AS [ORDER]
FROM
  ( SELECT CASE_ID,
           ID,
           ROW AS LP,
                  COL,
                  ROW_NUMBER() OVER (PARTITION BY CASE_ID, COL ORDER BY ROW) AS ROW1,
                  CASE_DATE
   FROM
     (SELECT ROW_NUMBER() OVER (PARTITION BY D.CASE_ID ORDER BY D.ID) AS ROW,
             NTILE(3/*@NUM*/) OVER (PARTITION BY D.CASE_ID ORDER BY D.ID) AS COL,
             ID,
             D.CASE_ID,
             CASE_DATE
      FROM DATA D
      WHERE D.CASE_ID = 1)X )Y
ORDER BY Y.CASE_ID,
         LP

修改：看起来您确实需要ORDER列，而不仅仅是按顺序返回列。

SELECT ID,
    CASE_ID,
    DATA,
    ROW_NUMBER() OVER (ORDER BY ROW, N) AS [ORDER]
FROM (
    SELECT ID,
        CASE_ID,
        N,
        ROW_NUMBER() OVER (PARTITION BY CASE_ID, N ORDER BY ID) AS ROW,
        DATA
    FROM (
        SELECT 
            ID, 
            CASE_ID,
            NTILE(3) OVER (PARTITION BY CASE_ID ORDER BY ID) AS N,
            CONVERT(NVARCHAR(10), CASE_DATE,121) AS DATA
        FROM DATA
        WHERE CASE_ID = 1 ) X ) Y
ORDER BY ID;

按ntile和row_number排序行
