使用Dynamic Pivot隱藏所有空值的行

Question

我問了一個問題，答案出現了，因爲我必須使用Dynamic Pivot Link to Question，我得到了很大的幫助。現在，我試圖擺脫所有空值的行，但我不能。

*請注意，目前的結果列標題應該是01部分，第一部分ABC，和第03（如圖所示不爲0）

WHERE SubPart IS NOT NULL/ WHERE Quantity IS NOT NULL 

，但它不工作（當然，它仍然查詢但空值）

後，從又從聲明

DECLARE @columns NVARCHAR(MAX)  
     ,@sql NVARCHAR(MAX) 

SET @columns = N'' 
--Get column names for entire pivoting 
SELECT @columns += N', ' + QUOTENAME(SpreadCol) 
    FROM (select distinct Part_Number as SpreadCol 
     from test 
     ) AS T 
--select @columns 
SET @sql = N' 
SELECT SubPart, ' + STUFF(@columns, 1, 2, '') + ' 
FROM 
(select SubPart , Part_Number as SpreadCol , Quantity 
from test) as D 
PIVOT 
(
    sum(Quantity) FOR SpreadCol IN (' 
    + STUFF(REPLACE(@columns, ', [', ',['), 1, 1, '') 
    + ') 
) AS Pivot1 
' 
--select @sql 

EXEC sp_executesql @sql

您需要添加的地方CON dition到用作源piovot和列清單查詢

DECLARE @columns NVARCHAR(MAX)  
     ,@sql NVARCHAR(MAX) 

SET @columns = N'' 
--Get column names for entire pivoting 
SELECT @columns += N', ' + QUOTENAME(SpreadCol) 
    FROM (select distinct Part_Number as SpreadCol 
     from test WHERE Quantity IS NOT NULL 
     ) AS T 
--select @columns 
SET @sql = N' 
SELECT SubPart, ' + STUFF(@columns, 1, 2, '') + ' 
FROM 
(select SubPart , Part_Number as SpreadCol , Quantity 
from test WHERE Quantity IS NOT NULL ) as D 
PIVOT 
(
    sum(Quantity) FOR SpreadCol IN (' 
    + STUFF(REPLACE(@columns, ', [', ',['), 1, 1, '') 
    + ') 
) AS Pivot1 
'
