如果为空，则将列单元格向上移动

Question

我试图从sql语句格式化结果集以放入水晶报表的命令。如果行单元格为空，我需要它向上移动。我知道这不是SQL所做的，但它是客户端规范。我有一个例子在这里，http://sqlfiddle.com/#!3/76999/11

，这是我现在有

在此先感谢

试试这个并让我知道它是如何工作的：

WITH DATA1 (ID, TaxCode) 
AS 
(SELECT ROW_NUMBER() OVER (ORDER BY TaxCode desc) AS ID, A.TaxCode FROM Table A) 

, DATA2 (ID, OwnerTax) 
AS 
(SELECT ROW_NUMBER() OVER (ORDER BY Ownertax desc) AS ID, A.OwnerTax FROM Table A) 

, DATA3 (ID, OwnerOther) 
AS 
(SELECT ROW_NUMBER() OVER (ORDER BY OwnerOther desc) AS ID, A.OwnerOther FROM Table A) 

, DATA4 (ID, DEDCode) 
AS 
(SELECT ROW_NUMBER() OVER (ORDER BY DEDCode desc) AS ID, A.DEDCode FROM Table A) 

SELECT DATA1.TaxCode, DATA2.OwnerTax, DATA3.OwnerOther, DATA4.DEDCode 
FROM DATA1 
LEFT JOIN DATA2 ON DATA1.ID = DATA2.ID 
LEFT JOIN Data3 ON DATA1.ID = DATA3.ID 
LEFT JOIN Data4 ON DATA1.ID = DATA4.ID 

的SQL下面将工作的链接，如果您复制http://sqlfiddle.com/#!3/76999/11并将其直接粘贴到右边的窗口：

With Source1 (TaxCode, OwnerTax, OwnerOther, dedCode) 
As(
SELECT 
CASE WHEN [Adjdesc] = 'TAX' THEN [TaxCode] ELSE null END AS TaxCode, 
CASE WHEN [Adjdesc] = 'TAX' THEN [adj] END AS OwnerTax, 
CASE WHEN [Adjdesc] <> 'TAX' THEN [adj] END AS OwnerOther, 
CASE WHEN [Adjdesc] <> 'TAX' THEN [TaxCode] ELSE null END AS dedCode 

FROM test4 AS A 
WHERE adj IS NOT NULL) 

, DATA1 (ID, TaxCode) 
AS 
(SELECT ROW_NUMBER() OVER (ORDER BY TaxCode desc) AS ID, A.TaxCode FROM Source1 A) 

, DATA2 (ID, OwnerTax) 
AS 
(SELECT ROW_NUMBER() OVER (ORDER BY Ownertax desc) AS ID, A.OwnerTax FROM Source1 A) 

, DATA3 (ID, OwnerOther) 
AS 
(SELECT ROW_NUMBER() OVER (ORDER BY OwnerOther desc) AS ID, A.OwnerOther FROM Source1 A) 

, DATA4 (ID, DEDCode) 
AS 
(SELECT ROW_NUMBER() OVER (ORDER BY DEDCode desc) AS ID, A.DEDCode FROM Source1 A) 

SELECT DATA1.TaxCode, DATA2.OwnerTax, DATA3.OwnerOther, DATA4.DEDCode 
FROM DATA1 
LEFT JOIN DATA2 ON DATA1.ID = DATA2.ID 
LEFT JOIN Data3 ON DATA1.ID = DATA3.ID 
LEFT JOIN Data4 ON DATA1.ID = DATA4.ID
