PIVOT中的列未按照所需的顺序排列

Question

我刚开始使用SQL PIVOT，并且对列的排序有问题，并且对于如何纠正它很有帮助。我在这里和其他网站上筛选了几个与PIVOT相关的帖子，但没有直接相关的东西。

你会注意到我在每个查询中都添加了一个硬编码的OrderBy文件，但这并没有帮助，我认为这是皮托正在对列进行排序的[Description]字段。所以，目前的列从以下顺序从左到右显示：

[收费期]，[优]，[好]，[无临时]，[满意]，[不满意]，[非常好]。

相反，我需要按以下顺序：

[收费期]，[无临时]，[优]，[非常好]，[好]，[满意]，[不满意] 。

我开始认为它可能不是一个纯粹的关键问题 - 从来没有我可以使用一些帮助，谢谢。

存储过程是这样的：

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) 

的观点[vQualScoringGrade]哺养存储过程是这样的：

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

试试这样说：

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

Answer 2

你指定你想在这里按字母顺序排列的列：

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

通过添加ORDER BY子句。

如果每个描述都有关联的列顺序字段，您可以对其进行排序以获得明确的顺序。

另外：通常从查询返回的列顺序并不重要。使用数据的应用程序负责格式化数据。该owuld包括以适当的顺序显示它。
