I am interested in converting a date value to CYYMMDD using native SQL Server 2012 functions.
I checked here:
http://www.sql-server-helper.com/tips/date-formats.aspx
and couldn't find anything.
Anyone know?
C stands for century I guess...
Have you looked at the new FORMAT function in SQL Server 2012?
http://msdn.microsoft.com/en-us/library/hh213505.aspx
You should be able to use something like this:
SELECT FORMAT(YourDateColumn, 'yyyyMMdd')
or whatever you really want to use - basically, the same formatting options as in C# / .NET are available when using FORMAT

How do you convert SQL mm/dd/yy datetime to mm/dd only? On Microsoft server.
Thanks all.
With dates and times it is an extremely common mistake to believe that what you see is what is stored. If the field is date, datetime, smalldatetime or datetime2 then what is stored are integers, not strings. So if the field is one of these, then:
convert(varchar(5),[date_field],1)
or
format([date_field],'MM/dd') -- mssql 2012 onward
If the information is a string already then left() will do the job.
Since you have specified an input format, the input must already be a string. Simply truncate with
cast(dateIn as char(5)).
You can use LEFT to just return the day and month:
SELECT LEFT('12/12/2000', 5)
I realize this isn't directly answering your question the way you asked it, but the best advice I can give is: Don't.
Instead, send back the field in its native datetime type. The database is not the place to be doing formatting. Instead, format the date in your application code.
For example, if you are calling SQL Server from a C#/.NET application, you could retrieve the value from a DataReader like this:
DateTime dt = (DateTime) reader["YourDateTime"];
Then you would format it as a string like this:
string s = dt.ToString("MM/dd");
This will ensure that the date is formatted correctly. If you are using a different language to call SQL Server, there are probably similar methods in that language.
One of the problems with the other approach mentioned (trunacating the string) is that the original value might not be formatted in mm/dd/yyyy to begin with. That all depends on the environment settings where the SQL Server is running. If you run the same code on an environment with dd/mm/yyyy settings, you would have unexpected results. This is avoided by using the native data type, the way I described.
I know there's a way to do this in regular Sql Server, and if I'm not mistaken, it looks something like this:
SELECT UNIX_TIMESTAMP(ba_trans_entered) * 1000 AS 'dateUTC'
I do admit, however, that I don't get the * 1000 part, but that's beside the point.
When I try to perform this query in SQL Server CE it just tells me (i.e., WebMatrix tells me):
'UNIX_TIMESTAMP' is not a recognized built-in function name.
I'm assuming UNIX_TIMESTAMP is not supported in Sql Server Compact.
Also, I tried Googling and searching here on SE but no data relevant to SQL Server CE shows up, so there may not be a way in the given environment.
Is there any way to convert 'datetime' (example: 7/13/2007 12:00:00 AM) to timestamp (example: 1184302800000)? I know I can do this in JavaScript, but I was told it might be faster to do this in the query itself, and since I am pulling a ton of data...
The UNIX_TIMESTAMP function does not exist in SQL Server on SQL Server Compact, but you can use DATEDIFF:
DATEDIFF(SECOND,{d '1970-01-01'}, ba_trans_entered)
Our application using SQL SERVER 2005
I need to show only DATE from DateTime in GridView.
I don't want to convert it into any other format like Varchar or something.
It should be only in DateTime format itself, without Time.
Please Help.
In SQL Server, the code is
CAST(datediff(d,0,datetimecol) as datetime)
However, I doubt that does any good for a GridView, which will infer it to be a "datetime" column and show a "date + time" formatting, even if the times are ALL "00:00:00".
Bound the DateField coloumn in Grid like below, then it works...
<asp:BoundField DataField="Your_Date_Column"
HeaderText="Date_Column"
DataFormatString="{0:d}" />
DataFormatString="{0:d}" it display the Date like 3/11/2013
In SQL 2005 there is no way of keeping it in datetime format without the time (time is part of the datetime type), the best you could get would be something like:
2013-04-02 00:00:00.000
If you were willing to convert to VARCHAR, you could use something similar to:
SELECT CONVERT(VARCHAR(10),GETDATE(),111)
Which would display the date portion as you want it. Otherwise, you need to move to SQL 2008+ where there is a proper date type that you can use instead.
If you need to stick with SQL 2005, the best way to achive this is to just format it in the datagrid view itself.
If you want to truncate a datetime so that it only returns the date as at midnight, see the accepted answer to this question - the question relates specifically to SQLServer 2008, but the answer includes details of how to achieve this in SQLServer 2005.
If you want to convert a datetime field into a date-only field - you cannot achieve this in SQLServer 2005 in SQL alone, as there is no date-only datatype - see here.
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.
I'm trying to remember the syntax to change a date field into a string. I know I'm close but not 100% correct. Here is what I'm using so far: TO_CHAR(FIELD_NAME). I'm using an Access database. The error I'm getting is: undefined expression. Any help would be very much appreciated.
Use either CStr(dateField) or Format(dateField) to convert.
Additionally you can add parameters to Format() to show it in a different format, such as:
Format(dateField, "general date") 9/12/2010
Format(dateField, "long date") Monday, September 12, 2011
Given that you're using MS Access and its a date field you're probably not just looking to convert to string but to also format the Date. If that is indeed the case you'll want the Format function
SELECT Format ([DateCreate], "yyyy/mm/dd") AS Foo
FROM MSysObjects;
If you're using SQL Server, try out CAST or CONVERT
You can use the CONVERT function, like this:
CONVERT(VARCHAR, DateField, 100)
Here's a link that shows the different date formats you can use:
http://www.sql-server-helper.com/tips/date-formats.aspx
I assume SQL Server as you're questions in the past are .NET Questions.
Use CONVERT
