SELECT GETDATE()
Returns: 2008-09-22 15:24:13.790
I want that date part without the time part: 2008-09-22 00:00:00.000
How can I get that?

NOTE: This answer returns the original DATETIME
or DATETIME2
type. For an expression that returns a true DATE
type (SQL Server 2008 and later), see BenR's answer below.
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, @your_date))
for example
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))
gives me
2008-09-22 00:00:00.000
Pros:
datetime
data type cannot have no time at all. I think you are confusing data storage with user presentation. If all you want is a way to show a user a string that has no time portion (not zeroes, just blanks) then you simply want Convert(varchar(30), @Date, 101)
or something similar. See SQL Server Books Online • Cast and Convert for more info.
CAST(... AS DATE)
or CONVERT(DATE, ...)
, which has been mentioned quite often on this very page.
SELECT DATEADD(dd, DATEDIFF(dd, 0, @your_date), 0)
because then dd
can be swapped out for any other datepart
keyword to truncate your datetime
at an arbitrary level.

SQLServer 2008 now has a 'date' data type which contains only a date with no time component. Anyone using SQLServer 2008 and beyond can do the following:
SELECT CONVERT(date, GETDATE())
If using SQL 2008 and above:
select cast(getdate() as date)
DateTime2
instead and it works fine. sqlfiddle.com/#!6/9eecb7/2833

2015-10-01
, due to DateTime
limitations. Try without any cast to Date
, it yields 2015-10-01
too! declare @date1 datetime = '2015-09-30 23:59:59.999';select @date1
=> 2015-10-01
DATEADD and DATEDIFF are better than CONVERTing to varchar. Both queries have the same execution plan, but execution plans are primarily about data access strategies and do not always reveal implicit costs involved in the CPU time taken to perform all the pieces. If both queries are run against a table with millions of rows, the CPU time using DateDiff can be close to 1/3rd of the Convert CPU time!
To see execution plans for queries:
set showplan_text on
GO
Both DATEADD and DATEDIFF will execute a CONVERT_IMPLICIT.
Although the CONVERT solution is simpler and easier to read for some, it is slower. There is no need to cast back to DateTime (this is implicitly done by the server). There is also no real need in the DateDiff method for DateAdd afterward as the integer result will also be implicitly converted back to DateTime.
SELECT CONVERT(varchar, MyDate, 101) FROM DatesTable
|--Compute Scalar(DEFINE:([Expr1004]=CONVERT(varchar(30),[TEST].[dbo].[DatesTable].[MyDate],101)))
|--Table Scan(OBJECT:([TEST].[dbo].[DatesTable]))
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, MyDate)) FROM DatesTable
|--Compute Scalar(DEFINE:([Expr1004]=dateadd(day,(0),CONVERT_IMPLICIT(datetime,datediff(day,'1900-01-01 00:00:00.000',CONVERT_IMPLICIT(datetime,[TEST].[dbo].[DatesTable].[MyDate],0)),0))))
|--Table Scan(OBJECT:([TEST].[dbo].[DatesTable]))
Using FLOOR() as @digi suggested has performance closer to DateDiff, but is not recommended as casting the DateTime data type to float and back does not always yield the original value.
Remember guys: Don't believe anyone. Look at the performance statistics, and test it yourself!
Be careful when you're testing your results. Selecting many rows to the client will hide the performance difference because it takes longer to send the rows over the network than it does to perform the calculations. So make sure that the work for all the rows is done by the server but there is no row set sent to the client.
There seems to be confusion for some people about when cache optimization affects queries. Running two queries in the same batch or in separate batches has no effect on caching. So you can either expire the cache manually or simply run the queries back and forth multiple times. Any optimization for query #2 would also affect any subsequent queries, so throw out execution #1 if you like.
Here is full test script and performance results that prove DateDiff is substantially faster than converting to varchar.
Try this:
SELECT CONVERT(VARCHAR(10),GETDATE(),111)
The above statement converts your current format to YYYY/MM/DD
, please refer to this link to choose your preferable format.
Just do:
SELECT CAST(date_variable AS date)
or with with PostgreSQL:
SELECT date_variable::date
This is called typecasting btw!
For return in date format
CAST(OrderDate AS date)
The above code will work in sql server 2010
It will return like 12/12/2013
For SQL Server 2012 use the below code
CONVERT(VARCHAR(10), OrderDate , 111)
You can use the CONVERT
function to return only the date. See the link(s) below:
Date and Time Manipulation in SQL Server 2000
The syntax for using the convert function is:
CONVERT ( data_type [ ( length ) ] , expression [ , style ] )
If you need the result as a varchar
, you should go through
SELECT CONVERT(DATE, GETDATE()) --2014-03-26
SELECT CONVERT(VARCHAR(10), GETDATE(), 111) --2014/03/26
which is already mentioned above.
If you need result in date and time format, you should use any of the queries below
SELECT CONVERT(DATETIME, CONVERT(VARCHAR(10), GETDATE(), 111)) AS OnlyDate
2014-03-26 00:00:00.000
SELECT CONVERT(DATETIME, CONVERT(VARCHAR(10), GETDATE(), 112)) AS OnlyDate
2014-03-26 00:00:00.000
DECLARE @OnlyDate DATETIME
SET @OnlyDate = DATEDIFF(DD, 0, GETDATE())
SELECT @OnlyDate AS OnlyDate
2014-03-26 00:00:00.000
Use Format()
function.
There are already multiple answers and formatting types for SQL server. But most of the methods are somewhat ambiguous and it would be difficult for you to remember the numbers for format type or functions with respect to Specific Date Format. That's why in next versions of SQL server there is better option.
FORMAT ( value, format [, culture ] )
Culture option is very useful, as you can specify date as per your viewers.
You have to remember d (for small patterns) and D (for long patterns).

Using FLOOR() - just cut time part.
SELECT CAST(FLOOR(CAST(GETDATE() AS FLOAT)) AS DATETIME)
SELECT CONVERT(VARCHAR,DATEADD(DAY,-1,GETDATE()),103) --21/09/2011
SELECT CONVERT(VARCHAR,DATEADD(DAY,-1,GETDATE()),101) --09/21/2011
SELECT CONVERT(VARCHAR,DATEADD(DAY,-1,GETDATE()),111) --2011/09/21
SELECT CONVERT(VARCHAR,DATEADD(DAY,-1,GETDATE()),107) --Sep 21, 2011
SELECT DATEADD(DD, DATEDIFF(DD, 0, GETDATE()), 0)
SELECT DATEADD(DAY, 0, DATEDIFF(DAY,0, GETDATE()))
SELECT CONVERT(DATETIME, CONVERT(VARCHAR(10), GETDATE(), 101))
Edit: The first two methods are essentially the same, and out perform the convert to varchar method.
select dateadd(dd, datediff(dd, 0, getdate()), 0)
, because the dd
s can then be swapped out for any of the datepart
keywords to clip the date at any segment you choose. (Also note that dd
is just an abbreviation for day
.)
Aug 14, 2014 at 16:02
DECLARE @myDate DATETIME2 = '2020-12-31 23:59:59.998911';
SELECT @myDate AS orig_date, DATEADD(dd, 0, DATEDIFF(dd, 0, @myDate)) AS truncated_date
It results as orig_date: 2020-12-31 23:59:59.9989110 truncated_date: 2021-01-01 00:00:00.000

IF you want to use CONVERT and get the same output as in the original question posed, that is, yyyy-mm-dd then use CONVERT(varchar(10),[SourceDate as dateTime],121)
same code as the previous couple answers, but the code to convert to yyyy-mm-dd with dashes is 121.
If I can get on my soapbox for a second, this kind of formatting doesn't belong in the data tier, and that's why it wasn't possible without silly high-overhead 'tricks' until SQL Server 2008 when actual datepart data types are introduced. Making such conversions in the data tier is a huge waste of overhead on your DBMS, but more importantly, the second you do something like this, you have basically created in-memory orphaned data that I assume you will then return to a program. You can't put it back in to another 3NF+ column or compare it to anything typed without reverting, so all you've done is introduced points of failure and removed relational reference.
You should ALWAYS go ahead and return your dateTime data type to the calling program and in the PRESENTATION tier, make whatever adjustments are necessary. As soon as you go converting things before returning them to the caller, you are removing all hope of referential integrity from the application. This would prevent an UPDATE or DELETE operation, again, unless you do some sort of manual reversion, which again is exposing your data to human/code/gremlin error when there is no need.
WHERE col >= @Date AND col < DATEADD(DAY, 1, @Date);
- there is absolutely no reason to strip time from the column.
Nov 16, 2013 at 5:09
@Date
has a zero time part. In case that isn't true, you still need to know how to truncate times server-side. I agree with this answer that formatting should be left to the presentation layer, but I didn't agree with an implication that leaving that for the front end means you don't have to know a quick way to truncate.

To obtain the result indicated, I use the following command.
SELECT CONVERT(DATETIME,CONVERT(DATE,GETDATE()))
I holpe it is useful.
Date:
SELECT CONVERT(date, GETDATE()) SELECT CAST(GETDATE() as date)
Time:
SELECT CONVERT(time , GETDATE() , 114) SELECT CAST(GETDATE() as time)
If you are assigning the results to a column or variable, give it the DATE type, and the conversion is implicit.
DECLARE @Date DATE = GETDATE()
SELECT @Date --> 2017-05-03
Convert(nvarchar(10), getdate(), 101) ---> 5/12/14
Convert(nvarchar(12), getdate(), 101) ---> 5/12/2014
Syntax:
SELECT CONVERT (data_type(length)),Date, DateFormatCode)
Ex:
Select CONVERT(varchar,GETDATE(),1) as [MM/DD/YY]
Select CONVERT(varchar,GETDATE(),2) as [YY.MM.DD]
all dateformatcodes about Date:
DateFormatCode Format
1 [MM/DD/YY]
2 [YY.MM.DD]
3 [DD/MM/YY]
4 [DD.MM.YY]
5 [DD-MM-YY]
6 [DD MMM YY]
7 [MMM DD,YY]
10 [MM-DD-YY]
11 [YY/MM/DD]
12 [YYMMDD]
23 [yyyy-mm-dd]
101 [MM/DD/YYYY]
102 [YYYY.MM.DD]
103 [DD/MM/YYYY]
104 [DD/MM/YYYY]
105 [DD/MM/YYYY]
106 [DD MMM YYYY]
107 [MMM DD,YYYY]
110 [MM-DD-YYYY]
111 [YYYY/MM/DD]
112 [YYYYMMDD]
Simply you can do this way:
SELECT CONVERT(date, getdate())
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, @your_date))
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))
Outputs as:
2008-09-22 00:00:00.000
Or simply do like this:
SELECT CONVERT (DATE, GETDATE()) 'Date Part Only'
Result:
Date Part Only
--------------
2013-07-14
In this case, date only, you we are gonna run this query:
I think this would work in your case:
CONVERT(VARCHAR(10),Person.DateOfBirth,111) AS BirthDate
//here date is obtained as 1990/09/25
DECLARE @yourdate DATETIME = '11/1/2014 12:25pm'
SELECT CONVERT(DATE, @yourdate)
Okay, Though I'm bit late :), Here is the another solution.
SELECT CAST(FLOOR(CAST(GETDATE() AS FLOAT)) as DATETIME)
Result
2008-09-22 00:00:00.000
And if you are using SQL Server 2012 and higher then you can use FORMAT()
function like this -
SELECT FORMAT(GETDATE(), 'yyyy-MM-dd')
Starting from SQL SERVER 2012, you can do this:
SELECT FORMAT(GETDATE(), 'yyyy-MM-dd 00:00:00.000')
Even using the ancient MSSQL Server 7.0, the code here (courtesy of this link) allowed me to get whatever date format I was looking for at the time:
PRINT '1) Date/time in format MON DD YYYY HH:MI AM (OR PM): ' + CONVERT(CHAR(19),GETDATE())
PRINT '2) Date/time in format MM-DD-YY: ' + CONVERT(CHAR(8),GETDATE(),10)
PRINT '3) Date/time in format MM-DD-YYYY: ' + CONVERT(CHAR(10),GETDATE(),110)
PRINT '4) Date/time in format DD MON YYYY: ' + CONVERT(CHAR(11),GETDATE(),106)
PRINT '5) Date/time in format DD MON YY: ' + CONVERT(CHAR(9),GETDATE(),6)
PRINT '6) Date/time in format DD MON YYYY HH:MM:SS:MMM(24H): ' + CONVERT(CHAR(24),GETDATE(),113)
It produced this output:
1) Date/time in format MON DD YYYY HH:MI AM (OR PM): Feb 27 2015 1:14PM
2) Date/time in format MM-DD-YY: 02-27-15
3) Date/time in format MM-DD-YYYY: 02-27-2015
4) Date/time in format DD MON YYYY: 27 Feb 2015
5) Date/time in format DD MON YY: 27 Feb 15
6) Date/time in format DD MON YYYY HH:MM:SS:MMM(24H): 27 Feb 2015 13:14:46:630
why don't you use DATE_FORMAT( your_datetiem_column, '%d-%m-%Y' ) ?
EX: select DATE_FORMAT( some_datetime_column, '%d-%m-%Y' ) from table_name
you can change sequence of m,d and year by re-arranging '%d-%m-%Y'
part
I know this is old, but I do not see where anyone stated it this way. From what I can tell, this is ANSI standard.
SELECT CAST(CURRENT_TIMESTAMP AS DATE)
It would be good if Microsoft could also support the ANSI standard CURRENT_DATE variable.
I favor the following which wasn't mentioned:
DATEFROMPARTS(DATEPART(yyyy, @mydatetime), DATEPART(mm, @mydatetime), DATEPART(dd, @mydatetime))
It also doesn't care about local or do a double convert -- although each 'datepart' probably does math. So it may be a little slower than the datediff method, but to me it is much more clear. Especially when I want to group by just the year and month (set the day to 1).
