Question

我有一张桌子：

Id    Date        color
------------------------- 
 1    23/04/2013  red
 2    23/04/2013  white
 3    23/04/2013  yellow
 4    23/04/2013  red
 5    23/04/2013  orange
 6    23/04/2013  blue
 7    23/04/2013  yellow
 8    23/04/2013  red

我按颜色和顺序按总和颜色分组：

Select top 5 color, count(color) as total from table where Date<=getdate() group by color order by total desc, color asc

所以直到这里，一切都好。

现在，我想要一样，但不要按颜色排序。我想按总数排序，然后按日期排序。但我不想按日期分组。

试试这个 -

DECLARE @temp TABLE
(
      Id INT IDENTITY(1,1)
    , [Date] DATETIME
    , color NVARCHAR(50)
)

INSERT INTO @temp ([Date], color)
VALUES 
    ('20130423',  'red'),
    ('20130422',  'white'),
    ('20130423',  'yellow'),
    ('20130423',  'red'),
    ('20130425',  'orange'),
    ('20130423',  'blue'),
    ('20130423',  'yellow'),
    ('20130423',  'red')

SELECT TOP 5 color, total = COUNT(color)  
FROM @temp 
WHERE [Date] <= GETDATE() 
GROUP BY color 
ORDER BY total DESC, MAX([Date])

Sql server按不同的字段顺序选择组
