我做了一个查询，返回给我每天创建的存储过程的计数，如下所示

SELECT  convert(varchar, crdate, 103) as Date,Count(*) as Counter
FROM    sysobjects
WHERE   (xtype = 'p') AND (name NOT LIKE 'dt%')
Group by  convert(varchar, crdate, 103)

并且它已经工作了，但是日期以字符串格式出现，我无法订购它，如下所示

01/03/2010  3
01/04/2008  4
01/05/2010  5
01/11/2008  1
01/12/2008  4
02/03/2008  1
02/03/2010  2
02/04/2008  4
02/05/2010  2
02/11/2008  2
02/11/2009  2
02/12/2008  4
03/01/2010  1
03/02/2010  2
03/03/2010  2
03/04/2008  2
03/04/2010  2
03/05/2008  1
03/05/2010  2

我想制作可以order by成功制作的日期时间格式的日期，我试过 convert(datetime, crdate, 103)但它显示完整日期

有什么想法吗？

要获得可排序的日期，您需要年、月、日。使用格式“112”。

SELECT  convert(varchar, crdate, 112) as Date,Count(*) as Counter
FROM    sysobjects
WHERE   (xtype = 'p') AND (name NOT LIKE 'dt%')
Group by  convert(varchar, crdate, 112)
order by  Date

这给出了这个：

Date        Counter
20040711    124
20040713    1
20040725    1
20040726    2
20040803    6

如果您想获得正确的排序顺序但格式不同的日期，那么您可以使用这样的子查询。

select CONVERT(varchar, GroupDate, 103) Date, Counter
FROM (
    SELECT  MIN(crdate) as GroupDate,Count(*) as Counter
    FROM    sysobjects
    WHERE   (xtype = 'p') AND (name NOT LIKE 'dt%')
    Group by  convert(varchar, crdate, 112)
) A
order by  GroupDate

产生

Date        Counter
11/07/2004  124
13/07/2004  1
25/07/2004  1
26/07/2004  2
03/08/2004  6

这个怎么样：

select dt, COUNT(*) from
(
    SELECT  convert(datetime, convert(varchar, crdate, 112)) as dt
    FROM    sysobjects
    WHERE   (xtype = 'p') AND (name NOT LIKE 'dt%')
) DayOnly
group by dt
order by dt asc

SELECT DATEADD(day, DATEDIFF(day, 0, o.crdate), 0) [Date],
       COUNT(*) [Counter]
FROM sys.sysobjects o
WHERE o.xtype = 'p' AND o.name NOT LIKE 'dt%'
GROUP BY DATEADD(day, DATEDIFF(day, 0, o.crdate), 0)
