I've got a table with a column DATEDEPOT
as varchar(20)
.
The information inside are like this : 20020101
- I mean YYYYMMDD
I would like to convert this in datetime.
For this, I check the answer to other post but nothing is working for me.
Here is what I tried:
select datedepot, cast(datedepot as datetime) as test from DessinsV2
I get this message :
Msg 241, Niveau 16, État 1, Ligne 1.
Échec de la conversion de la date et/ou de l'heure à partir d'une chaîne de caractères.
I've tried this :
declare @Madate char(10)
SELECT @MaDate=datedepot from DessinsV2
select convert(datetime,left(@Madate,4)+substring(@Madate,5,2)+right(@Madate,2))as DATEDEPOTTEST from dessinsv2
and I get :
Msg 241, Niveau 16, État 1, Ligne 1
Échec de la conversion de la date et/ou de l'heure à partir d'une chaîne de caractères.
Does this run on your machine?
DECLARE @var as nvarchar(20)
SELECT @var = '20020101'
SELECT CONVERT(datetime, @var)
This query works for me, but not if I use a date string of the format 'DDMMYYYY'.
See http://msdn.microsoft.com/en-us/library/ms187819.aspx for more on datetime.
select '20020101' as orignal_date,
cast('20020101' as datetime) as converted_date
This Work Fine with me Please Check.
You must specify date input format to the convert function like :
select datedepot, convert(datetime, datedepot,112) as test from DessinsV2
see: http://msdn.microsoft.com/es-es/library/ms187928.aspx for more formats.
Thanks Everybody for helping.
My query was good but i made a query to 'group by' and i found some irregular contents like special caracter or special digit. Those information couldn't be converted.
So i ignore the line with strange information and my query is working fine.
