How to return only the Date from a SQL Server DateTime datatype

Asked 2023-09-20 20:55:21 View 410,276
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?

Answers

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:

  • No varchar<->datetime conversions required
  • No need to think about locale

  • +1 Looks like this one is 35% faster than the double convert() method commonly used (which I also have used for years). Nice one. - anyone
  • The only downside I can see to your solution is that unless you know what it is doing it is a bit obtuse. Using the double convert method makes your intentions more obvious to futire code maintainers. BTW I have not downvoted you. I think I'll start using your method too. Thankyou @aku - anyone
  • @pilavdzice Setting a datetime to midnight of that day does LEAVE OFF THE TIME. What result are you expecting? The 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. - anyone
  • @user1671639 the datetime data type always contains both a date and a time, you can't sensibly store one without the other - unless you're using SQL Server 2008, in which case there are also separate 'date' and 'time' data types. If you use CONVERT() like that, you really want a string for later use, so you'll be stuck doing it like that - although it'd be better if you used date formatting functions instead of cutting the date off - or via CAST(... AS DATE) or CONVERT(DATE, ...), which has been mentioned quite often on this very page. - anyone
  • I recommend changing the answer to 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. - anyone

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())

  • One of these easy to remember SQL tricks. As Mike says, only 2008 onward but, if you find a 2005 and previous DB somewhere, you may have a lot of issues :) - anyone

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.

You can use the CONVERT function to return only the date. See the link(s) below:

The syntax for using the convert function is:

CONVERT ( data_type [ ( length ) ] , expression [ , style ] ) 

Answered   2023-09-20 20:55:21

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

  1. SELECT CONVERT(DATETIME, CONVERT(VARCHAR(10), GETDATE(), 111)) AS OnlyDate 
    

    2014-03-26 00:00:00.000

    2014-03-26 00:00:00.000

  3. DECLARE  @OnlyDate DATETIME
    SET @OnlyDate = DATEDIFF(DD, 0, GETDATE())
    SELECT @OnlyDate AS OnlyDate

If you are using SQL Server 2012 or above versions,

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).

1."d" - Short date pattern.

2009-06-15T13:45:30 -> 6/15/2009 (en-US)
2009-06-15T13:45:30 -> 15/06/2009 (fr-FR)
2009-06-15T13:45:30 -> 2009/06/15 (ja-JP)

2."D" - Long date pattern.

2009-06-15T13:45:30 -> Monday, June 15, 2009 (en-US)
2009-06-15T13:45:30 -> 15 июня 2009 г. (ru-RU)
2009-06-15T13:45:30 -> Montag, 15. Juni 2009 (de-DE)

More examples in query.

DECLARE @d DATETIME = '10/01/2011';
SELECT FORMAT ( @d, 'd', 'en-US' ) AS 'US English Result'
      ,FORMAT ( @d, 'd', 'en-gb' ) AS 'Great Britain English Result'
      ,FORMAT ( @d, 'd', 'de-de' ) AS 'German Result'

Using FLOOR() - just cut time part.

SELECT CAST(FLOOR(CAST(GETDATE() AS FLOAT)) AS DATETIME)

Answered   2023-09-20 20:55:21

  • This method is not the fastest, and also implicitly teaches people that casting dates to float is accurate, which it is not. Please see this post for more detail. - anyone

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.

  • Except, say, if you want a query that retrieves all records matching a user-supplied date as the date-part of a certain time field. Good luck doing that only in the presentation layer. (You don't need convert, you can can use date arithmetic, but you get the idea…) - anyone
  • @Andrew why does that matter? You say WHERE col >= @Date AND col < DATEADD(DAY, 1, @Date); - there is absolutely no reason to strip time from the column. - anyone
  • @AaronBertrand That only works assuming the input @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. - anyone
  • @Andrew all you have to do is make the input parameter DATE. My point is still that you should never have to apply any such truncation to the column, even though that is most people's first instinct. - anyone
  • @AaronBertrand and that assumes you have control over the datatype of the parameter. Fine in a stored procedure, not so possible in other situations. Why not cast to be sure the parameter is the type you want and need? - anyone
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.

Answered   2023-09-20 20:55:21

  • These methods are all great, but which single one do you suggest using? - anyone
  • Note that the "correct" version of the top two is select dateadd(dd, datediff(dd, 0, getdate()), 0), because the dds 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.) - anyone
  • be aware, that with the new DATETIME2 this truncation doesn't work every time correctly: 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 - anyone

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.

  • select {fn current_date()} as today works for me. - anyone
  • @brianary - That's nice, but it is not ANSI SQL. - anyone
  • That's fair enough, and your answer is nicely portable, but I figured as long as we're working around T-SQL, this also works (and shows that implementing ANSI CURRENT_DATE would be trivial for MS). - anyone

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).
