按时间顺序排序 FOR XML PATH

Question

我无法按时间顺序在 FOR XML Path 中订购季度和年份。虽然我订购它不起作用。有人可以告诉我哪里出错了

 SELECT DISTINCT 
    LON.DATE
    ,STUFF((SELECT DISTINCT   ',' + 'Q' + (COALESCE(CAST(LON1.QTR AS Varchar(10))+ '/ ', '') + + CAST(LON1.YR AS Varchar(10))) 
           FROM LOANTABLE LON1
           WHERE LON.DATE = LON1.DATE 
           FOR XML PATH('')),1,1,'') AS QuarterAndYear
FROM 
   LOANTABLE LON
GROUP BY 
   LON.DATE
ORDER BY 
   QuarterAndYear

这是结果数据：

Date               QuarterAndYear
2011-04-01         Q1/ 2008,Q3/ 2009,Q1/ 2010,Q2/ 2009,Q4/ 2009,Q2/ 2008,Q2/ 2010,Q3/ 2010,Q3/ 2008,Q4/ 2008,Q4/ 2010,Q1/ 2011,Q2/ 2011,Q1/ 
2009 2010-12-01    Q1/ 2010,Q2/ 2010,Q3/ 2010,Q4/ 
2010 2011-07-01    Q1/ 2010,Q3/ 2011,Q2/ 2010,Q3/ 2010,Q4/ 2010,Q1/ 2011,Q2/ 
2011 2012-01-09    Q1/ 2010,Q3/ 2011,Q2/ 2010,Q3/ 2010,Q4/ 2011,Q4/ 2010,Q1/ 2011,Q2/ 
2011 2011-07-08    Q1/ 2010,Q4/ 2009,Q2/ 2010,Q3/ 2010,Q4/ 2010,Q1/ 2011 –

使用以下格式：

 SELECT DISTINCT LON.DATE
                ,STUFF((SELECT DISTINCT   ',' + 'Q' + (COALESCE(CAST(z.QTR AS Varchar(10))+ '/ ', '') + + CAST(z.YR AS Varchar(10))) 
                       FROM (SELECT TOP 100 PERCENT QTR, YR
                             FROM LOANTABLE LON1
                             WHERE LON.DATE = LON1.DATE
                             ORDER BY LON1.QTR DESC
                             )z
                       FOR XML PATH('')),1,1,'') AS QuarterAndYear
FROM LOANTABLE LON
GROUP BY LON.DATE
ORDER BY QuarterAndYear
