I have SQL Server 2008 R2 and one of my tables has a date field. When an insert from my ASP.NET page happens, the date is automatically inserted by setting the default field value to getdate(). However, this adds the date in the format YYYY-MM-DD HH:MM:SS.0000000. I really only need the time up to seconds and not the trailing zeros after it.
How can I do this?
A DateTime, whether in SQL Server or .NET code does not have a format. It has an internal representation.
When you want to display the value of the DateTime you format it using a format string.
select (convert(char(19), getdate(), 121))
Gives:
2012-04-06 10:16:50
Up to SQL Server 2008 R2, all you can do is convert the datetime (stored as 8 bytes) you're getting back using a list of possible, supported formats - see the MSDN documentation on CAST and CONVERT for the complete list of supported formats.
With SQL Server 2012, you'll be able to use a FORMAT function much like in .NET - but again, that's a new function in the 2012 version, not available in earlier versions.

At the moment I have a column that holds timestamps as a datetime
The data is being stored as 10/30/2011 10:50:34 AM
My goal is to convert every date in that specific table to be formatted like 30 Oct 2011 10:50:34
The problem:
When I attempt to run this SQL it successfully processes.
UPDATE DatesTable
SET DateTime = '30 Oct 2011 10:50:34'
WHERE DateTime = '10/30/2011 10:50:34 AM'
I noticed that was weird so if I changed the SQL to say
UPDATE DatesTable
SET DateTime = '31 Oct 2011 10:50:34'
WHERE DateTime = '10/30/2011 10:50:34 AM'
It updates updates the datetime field with the correct day/time information but keeps it in the same format.
I have looked into other possible date datatypes for that column but nothing seems to support that date.
I have also come across this SQL but am unsure if it can solve my problem.
SELECT CONVERT(datetime, datecolumnname, formattingparam) as tmp FROM tablename

SQL Server doesn't store a DateTime in any string format - it's stored as an 8 byte numerical value.
The various settings (language, date format) only influence how the DateTime is shown to you in SQL Server Management Studio - or how it is parsed when you attempt to convert a string to a DateTime.
There are many formats supported by SQL Server - see the MSDN Books Online on CAST and CONVERT. Most of those formats are dependent on what settings you have - therefore, these settings might work some times - and sometimes not.
The way to solve this is to use the ISO-8601 date format that is supported by SQL Server - this format works always - regardless of your SQL Server language and dateformat settings.
The ISO-8601 format is supported by SQL Server comes in two flavors:
YYYYMMDD for just dates (no time portion) - note here: no dashes!, that's very important! YYYY-MM-DD is NOT independent of the dateformat settings in your SQL Server and will NOT work in all situations!
or:
YYYY-MM-DDTHH:MM:SS for dates and times - note here: this format has dashes.
This is valid for SQL Server 2000 and newer.
If you use SQL Server 2008 and the DATE datatype (only DATE - not DATETIME!), then you can indeed also use the YYYY-MM-DD format and that will work, too, with any settings in your SQL Server.
Don't ask me why this whole topic is so tricky and somewhat confusing - that's just the way it is. But with the YYYYMMDD format, you should be fine for any version of SQL Server and for any language and dateformat setting in your SQL Server.
The data is stored independent of format. You only need to reformat dates for display purposes.
sql server doesn't store the data in a text format. It is stored as a number.

The datetime datatype tells the database engine how to store the data internally, so that you don't need to worry about human representations of the data. This is why your different UPDATE scripts don't change the format. The format is only applied when converting from the database's internal storage (a number representing the amount of time passed since a particular starting-point) and a human-readable date in the culture you require. You just need to format the date when it gets displayed, in the format suitable for your users. For example, for many, Month/Day/Year makes no sense.
My date format of "03-01-2017 10:24:48" is getting stored in SQL as "2017-03-01 10:24:48.000" where my 'dd-mm-yyyy' format is getting converted to 'yyyy-mm-dd' format.
How can I change the date format of the column to my desired format? My table already contains data.

There are many formats supported by SQL Server - see the MSDN Books Online on CAST and CONVERT. Most of those formats are dependent on what settings you have - therefore, these settings might work some times - and sometimes not.
The way to solve this is to use the (slightly adapted) ISO-8601 date format that is supported by SQL Server - this format works always - regardless of your SQL Server language and dateformat settings.

YYYYMMDD for just dates (no time portion); note here: no dashes!, that's very important! YYYY-MM-DD is NOT independent of the dateformat settings in your SQL Server and will NOT work in all situations!
or:
YYYY-MM-DDTHH:MM:SS for dates and times - note here: this format has dashes (but they can be omitted), and a fixed T as delimiter between the date and time portion of your DATETIME.
This is valid for SQL Server 2000 and newer.
If you use SQL Server 2008 or newer and the DATE datatype (only DATE - not DATETIME!), then you can indeed also use the YYYY-MM-DD format and that will work, too, with any settings in your SQL Server.
Don't ask me why this whole topic is so tricky and somewhat confusing - that's just the way it is. But with the YYYYMMDD format, you should be fine for any version of SQL Server and for any language and dateformat setting in your SQL Server.
The recommendation for SQL Server 2008 and newer is to use DATE if you only need the date portion, and DATETIME2(n) when you need both date and time. You should try to start phasing out the DATETIME datatype if ever possible
Changing the format does not change the way the data is stored, just the way it is displayed. You can find date and time styles at https://msdn.microsoft.com/en-us/library/ms187928.aspx?f=255&MSPPError=-2147217396.
Currently am using below mentioned code
CONVERT(DATETIME, "16-05-2015 21:27:25.280",105)
Using this its working in my system culture and one of our client in UK.
But facing issue in our US client.
Error message:
The conversion of a nvarchar data type to a datetime data type resulted in an out-of-range value
So there any way to convert the string to DATETIME depends on system culture like in .net.
Thanks in advance

Impossible to store certain datetime formats in SQL Server
(4 answers)
Closed 9 years ago.
When application tries to insert data using this query (yyyy/mm/dd):
INSERT INTO Inv_Dueno_Equipo (Cod_Usuario, Fecha_Inicio, Fecha_Termino, Codigo_Equipo)
VALUES (1, '2012/01/26', '2012/01/31', 1);
I get an error
The conversion from data type varchar to datetime produced a value out of range.
But if I change query to (yyyy/dd/mm)
INSERT INTO Inv_Dueno_Equipo (Cod_Usuario, Fecha_Inicio, Fecha_Termino, Codigo_Equipo)
VALUES (1, '2012/26/01', '2012/31/01', 1);
data is inserted. How can I fix this, where configuration I need to change for yyyy/mm/dd format to work?
Thanks

So for your concrete case, try using:

VALUES (1, '20120126', '20120131', 1);
and you should be fine with that.

INSERT INTO Inv_Dueno_Equipo (Cod_Usuario,Fecha_Inicio,Fecha_Termino,Codigo_Equipo) VALUES (1,convert('2012/01/26',103),convert('2012/01/31',103),1);
