遇到一个德国的客户,他们的时间格式是JJJJ-TT-DD
HH:MM:SS,程序按照这个格式将时间插入数据库,但是在sql自带的转换函数convert、cast过程中报错,网上搜了下都说用convert、cast可以直接转换,但是这个客户的机器就是不行,没有办法自己写了个转换函数,供大家参考:
由于自定义函数里面不能直接使用getdate方法;所以先创建了个获取本地时间的小函数:
create view v_getdate as
select getdate()
as now_date
然后是转换函数:
1 CREATE FUNCTION ToDateTime(@DateStr varchar(20))
2 RETURNS datetime
3 AS
4 BEGIN
5 declare @OutTime datetime
6 select @OutTime=now_date from v_getdate
7 if(len(@DateStr)<20)
8 set @DateStr=substring(@DateStr+‘ 00:00:00‘,1,20)
9 set @OutTime=dateadd(year,0-year(@OutTime)+cast(substring(@DateStr,1,4) as int),@OutTime)
10 set @OutTime=dateadd(month,0-month(@OutTime)+cast(substring(@DateStr,6,2) as int),@OutTime)
11 set @OutTime=dateadd(day,0-day(@OutTime)+cast(substring(@DateStr,9,2) as int),@OutTime)
12 set @OutTime=dateadd(hour,0-DATEPART(HH,@OutTime)+cast(substring(@DateStr,12,2) as int),@OutTime)
13 set @OutTime=dateadd(minute,0-DATEPART(N,@OutTime)+cast(substring(@DateStr,15,2) as int),@OutTime)
14 set @OutTime=dateadd(second,0-DATEPART(S,@OutTime)+cast(substring(@DateStr,19,2) as int),@OutTime)
15 return @OutTime
16 END
调用示例:select dbo.ToDateTime(‘2014-04-05 06:07:08‘)
时间: 2024-10-09 00:30:01
