每天创建了多少个存储过程（转换日期中的问题）？

Question

我进行了一个查询，使我回到我的存储过程计数，每天创建如下

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)

它已经有效，但日期以字符串格式出现，我无法订购，例如下面

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

我想在哪个日期以日期为单位的格式中做到这一点 order by 成功，我尝试了 convert(datetime, crdate, 103) 但是它显示了全约日期

有什么想法如何做？

Answer 1

要获得可排序的日期，您需要年，然后一个月，然后日期。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

给出了这一点：

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

如果您想获得正确的排序订单但格式不同的日期，则可以使用类似的子查询。

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

哪个产生

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

Answer 2

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

Answer 3

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)
