PIVOT中的列未按照所需的順序排列

Question

我剛開始使用SQL PIVOT，並且對列的排序有問題，並且對於如何糾正它很有幫助。我在這裏和其他網站上篩選了幾個與PIVOT相關的帖子，但沒有直接相關的東西。

你會注意到我在每個查詢中都添加了一個硬編碼的OrderBy文件，但這並沒有幫助，我認爲這是皮託正在對列進行排序的[Description]字段。所以，目前的列從以下順序從左到右顯示：

[收費期]，[優]，[好]，[無臨時]，[滿意]，[不滿意]，[非常好]。

相反，我需要按以下順序：

[收費期]，[無臨時]，[優]，[非常好]，[好]，[滿意]，[不滿意] 。

我開始認爲它可能不是一個純粹的關鍵問題 - 從來沒有我可以使用一些幫助，謝謝。

存儲過程是這樣的：

DECLARE @cols NVARCHAR(MAX) 
DECLARE @query NVARCHAR(MAX) 

SET NOCOUNT ON; 
SET TRANSACTION ISOLATION LEVEL READ COMMITTED 

SELECT @cols = STUFF((SELECT DISTINCT TOP 100 PERCENT '],[' + [Description] 
FROM dbo.vQualScoringGrade 
ORDER BY '],[' + [Description] FOR XML PATH('')), 1,2,'') + ']' 

SET @query = N'SELECT [Fee Period], ' + @cols + ' FROM 
(SELECT [Award Fee Period],GradeCount, Description, Value, OrderBy FROM 
dbo.vQualScoringGrade) p 
PIVOT (SUM([Value]) for [Description] IN (' + @cols + ')) AS pvt ORDER BY [Fee Period]' 

execute(@query) 

的觀點[vQualScoringGrade]哺養存儲過程是這樣的：

SELECT TOP (100) PERCENT [Fee Period], GradeCount, Description, 
GradeCount AS Value, OrderBy 
FROM (SELECT [Fee Period], 'No of Interim' AS Description, COUNT(VerNumber) AS GradeCount, 1 AS 
OrderBy 
FROM dbo.vQualScoringExcellent AS vQualScoringExcellent 
GROUP BY GIIANumber, Description 
UNION 
SELECT [Fee Period], 'Excellent' AS Description, COUNT(Description) AS GradeCount, 2 AS OrderBy 
FROM dbo.vQualScoringExcellent AS vQualScoringExcellent_1 
GROUP BY VerNumber, Description 
UNION 
SELECT [Fee Period], 'Very Good' AS Description, COUNT(Description) AS GradeCount, 3 AS OrderBy 
FROM dbo.vQualScoringVeryGood AS vQualScoringVeryGood 
GROUP BY VerNumber, Description 
UNION 
SELECT [Fee Period], 'Good' AS Description, COUNT(Description) AS GradeCount, 4 AS OrderBy 
FROM dbo.vQualScoringGood AS vQualScoringGood 
GROUP BY VerNumber, Description 
UNION 
SELECT [Fee Period], 'Satisfactory' AS Description, COUNT(Description) AS GradeCount, 5 AS 
OrderBy 
FROM dbo.vQualScoringSatisfactory AS vQualScoringSatisfactory 
GROUP BY VerNumber, Description 
UNION 
SELECT [Fee Period], 'Unsatisfactory' AS Description, COUNT(Description) AS GradeCount, 6 AS OrderBy 
FROM dbo.vQualScoringUnsatisfactory AS vQualScoringUnsatisfactory 
GROUP BY VerNumber, Description) AS QualScoringGrade 
ORDER BY OrderBy 

Answer 1

試試這樣說：

SELECT @cols = STUFF((SELECT '],[' + [Description] 
    FROM dbo.vQualScoringGrade 
    GROUP BY [Description] 
    ORDER BY MAX([orderby]), [Description] 
    FOR XML PATH('')), 1,2,'') + ']' 

Answer 2

你指定你想在這裏按字母順序排列的列：

SELECT @cols = STUFF((SELECT DISTINCT TOP 100 PERCENT '],[' + [Description] 
    FROM dbo.vQualScoringGrade 
    ORDER BY '],[' + [Description] FOR XML PATH('')), 1,2,'') + ']' 

通過添加ORDER BY子句。

如果每個描述都有關聯的列順序字段，您可以對其進行排序以獲得明確的順序。

另外：通常從查詢返回的列順序並不重要。使用數據的應用程序負責格式化數據。該owuld包括以適當的順序顯示它。
