Here's some test sql for all the styles.
DECLARE @now datetime
SET @now = GETDATE()
select convert(nvarchar(MAX), @now, 0) as output, 0 as style
union select convert(nvarchar(MAX), @now, 1), 1
union select convert(nvarchar(MAX), @now, 2), 2
union select convert(nvarchar(MAX), @now, 3), 3

Make nvarchar(max) shorter to trim the time. For example:
select convert(nvarchar(11), GETDATE(), 0)
union select convert(nvarchar(max), GETDATE(), 0)
outputs:
May 18 2018
May 18 2018 9:57AM
Solution 2 - Sql
With Microsoft Sql Server:
--
-- Create test case
--
DECLARE @myDateTime DATETIME
SET @myDateTime = '2008-05-03'
--
-- Convert string
--
SELECT LEFT(CONVERT(VARCHAR, @myDateTime, 120), 10)
Solution 3 - Sql
Try the following:
CONVERT(varchar(10), [MyDateTimecolumn], 20)
For a full date time and not just date do:
CONVERT(varchar(23), [MyDateTimecolumn], 121)
See this page for convert styles:
http://msdn.microsoft.com/en-us/library/ms187928.aspx
OR
SQL Server CONVERT() Function
Solution 4 - Sql
SQL Server 2012 has a new function , FORMAT: http://msdn.microsoft.com/en-us/library/ee634924.aspx
and you can use custom date time format strings: http://msdn.microsoft.com/en-us/library/ee634398.aspx
These pages imply it is also available on SQL2008R2, but I don't have one handy to test if that's the case.
Example usage (Australian datetime):
FORMAT(VALUE,'dd/MM/yyyy h:mm:ss tt')
Solution 5 - Sql
You can use DATEPART(DATEPART, VARIABLE). For example:
DECLARE @DAY INT
DECLARE @MONTH INT
DECLARE @YEAR INT
DECLARE @DATE DATETIME
@DATE = GETDATE()
SELECT @DAY = DATEPART(DAY,@DATE)
SELECT @MONTH = DATEPART(MONTH,@DATE)
SELECT @YEAR = DATEPART(YEAR,@DATE)
Solution 6 - Sql
Either Cast or Convert:
Syntax for CAST:
CAST ( expression AS data_type [ (length ) ])
Syntax for CONVERT:
CONVERT ( data_type [ ( length ) ] , expression [ , style ] )
http://msdn.microsoft.com/en-us/library/ms187928.aspx
Actually since you asked for a specific format:
REPLACE(CONVERT(varchar(10), Date, 102), '.', '-')
Solution 7 - Sql
-- This gives you the time as 0 in format 'yyyy-mm-dd 00:00:00.000'
SELECT CAST( CONVERT(VARCHAR, GETDATE(), 101) AS DATETIME) ;
Solution 8 - Sql
With Microsoft SQL Server:
Use Syntax for CONVERT:
CONVERT ( data_type [ ( length ) ] , expression [ , style ] )
Example:
SELECT CONVERT(varchar,d.dateValue,1-9)
For the style you can find more info here: MSDN - Cast and Convert (Transact-SQL).
Solution 9 - Sql
For SQL Server 2008+ You can use CONVERT and FORMAT together.
For example, for European style (e.g. Germany) timestamp:
CONVERT(VARCHAR, FORMAT(GETDATE(), 'dd.MM.yyyy HH:mm:ss', 'de-DE'))
Solution 10 - Sql
Try the following:
CONVERT(VARCHAR(10),GetDate(),102)
Then you would need to replace the "." with "-".
Here is a site that helps http://www.mssqltips.com/tip.asp?tip=1145
Solution 11 - Sql
declare @dt datetime
set @dt = getdate()
select convert(char(10),@dt,120)
I have fixed data length of char(10) as you want a specific string format.
Solution 12 - Sql
Solution 13 - Sql
The OP mentioned datetime format. For me, the time part gets in the way.
I think it's a bit cleaner to remove the time portion (by casting datetime to date) before formatting.
convert( varchar(10), convert( date, @yourDate ) , 111 )
Solution 14 - Sql
This is how I do it: CONVERT(NVARCHAR(10), DATE1, 103) )
Solution 15 - Sql
The shortest and the simplest way is :
DECLARE @now AS DATETIME = GETDATE()
SELECT CONVERT(VARCHAR, @now, 23)
Solution 16 - Sql
You can convert your date in many formats, the syntaxe is simple to use :
CONVERT('TheTypeYouWant', 'TheDateToConvert', 'TheCodeForFormating' * )
CONVERT(NVARCHAR(10), DATE_OF_DAY, 103) => 15/09/2016
- The code is an integer, here 3 is the third formating without century, if you want the century just change the code to 103.
In your case, i've just converted and restrict size by nvarchar(10) like this :
CONVERT(NVARCHAR(10), MY_DATE_TIME, 120) => 2016-09-15
See more at : http://www.w3schools.com/sql/func_convert.asp
Another solution (if your date is a Datetime) is a simple CAST :
CAST(MY_DATE_TIME as DATE) => 2016-09-15
Solution 17 - Sql
Try this SQL:
select REPLACE(CONVERT(VARCHAR(24),GETDATE(),103),'/','_') + '_'+
REPLACE(CONVERT(VARCHAR(24),GETDATE(),114),':','_')
Solution 18 - Sql
You did not say which database, but with mysql here is an easy way to get a date from a timestamp (and the varchar type conversion should happen automatically):
mysql> select date(now());
+-------------+
| date(now()) |
+-------------+
| 2008-09-16 |
+-------------+
1 row in set (0.00 sec)
Solution 19 - Sql
CONVERT(VARCHAR, GETDATE(), 23)
Solution 20 - Sql
DECLARE @DateTime DATETIME
SET @DateTime = '2018-11-23 10:03:23'
SELECT CONVERT(VARCHAR(100),@DateTime,121 )
Solution 21 - Sql
select REPLACE(CONVERT(VARCHAR, FORMAT(GETDATE(), N'dd/MM/yyyy hh:mm:ss tt')),'.', '/')
will give 05/05/2020 10:41:05 AM as a result
Solution 22 - Sql
Write a function
CREATE FUNCTION dbo.TO_SAP_DATETIME(@input datetime)
RETURNS VARCHAR(14)
AS BEGIN
DECLARE @ret VARCHAR(14)
SET @ret = COALESCE(SUBSTRING(REPLACE(REPLACE(REPLACE(CONVERT(VARCHAR(26), @input, 25),'-',''),' ',''),':',''),1,14),'00000000000000');
RETURN @ret
END
Solution 23 - Sql
Simple use "Convert" and then use "Format" to get your desire date format
DECLARE @myDateTime DATETIME
SET @myDateTime = '2008-05-03'
SELECT FORMAT(CONVERT(date, @myDateTime ),'yyyy-MM-dd')
Solution 24 - Sql
You don't say what language but I am assuming C#/.NET because it has a native DateTime data type. In that case just convert it using the ToString method and use a format specifier such as:
DateTime d = DateTime.Today;
string result = d.ToString("yyyy-MM-dd");
However, I would caution against using this in a database query or concatenated into a SQL statement. Databases require a specific formatting string to be used. You are better off zeroing out the time part and using the DateTime as a SQL parameter if that is what you are trying to accomplish.
