SQL Server Pivot In子句

Question

我正在尝试这个，但它会以意想不到的“顺序返回结果......应该

2013-01,2013-02,2013-03等view_YearWeeks是一个视图，选择DISTINCT YearWeek从销售表中订购ASC ...如果执行它正确排序值，但在此

Select @colWeeks = isnull(@colWeeks + ', ','') + QUOTENAME(YearWeek) 
from 
    (select YearWeek 
     from dbo.YearWeeks) as weeks

它返回

[2014-33], [2014-48], [2013-13], etc

我该如何解决？

Answer 1

使用Order By在SQL Server中订购记录。

Declare @colWeeks nvarchar(1000) = N'';

Select @colWeeks = isnull(@colWeeks + ', ','') + QUOTENAME(YearWeek.YearWeek) 
From YearWeek
Order By YearWeek.YearWeek;
