How to select date without time in SQL

问题

When I select date in SQL it is returned as 2011-02-25 21:17:33.933. But I need only the Date part, that is 2011-02-25. How can I do this?

回答1:

I guess he wants a string

select convert(varchar(10), '2011-02-25 21:17:33.933', 120)

回答2:

For SQL Server 2008:

Convert(date, getdate())

Please refer to https://docs.microsoft.com/en-us/sql/t-sql/functions/getdate-transact-sql

回答3:

The fastest is datediff, e.g.

select dateadd(d, datediff(d,0, [datecolumn]), 0), other..
from tbl

But if you only need to use the value, then you can skip the dateadd, e.g.

select ...
WHERE somedate <= datediff(d, 0, getdate())

where the expression datediff(d, 0, getdate()) is sufficient to return today's date without time portion.

Use CAST(GETDATE() as date) that worked for me, simple.

回答5:

CAST(
        FLOOR( 
             CAST( GETDATE() AS FLOAT ) 
        )

AS DATETIME
)

回答6:

you can use like this

SELECT Convert(varchar(10), GETDATE(),120)

回答7:

For 2008 older version :

SELECT DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()), 0)

回答8:

It's a bit late, but use the ODBC "curdate" function (angle brackes 'fn' is the ODBC function escape sequence).

SELECT {fn curdate()}

Output: 2013-02-01

回答9:

You can try this one too.

SELECT CONVERT(DATE, GETDATE(), 120)

回答10:

In case if you need the time to be zeros :

SELECT CONVERT(DATETIME, CONVERT(DATE, GETDATE()), 120)

回答11:

Use is simple:

convert(date, Btch_Time)

Example below:

Table:

Efft_d       Loan_I  Loan_Purp_Type_C   Orig_LTV    Curr_LTV    Schd_LTV    Un_drwn_Bal_a      Btch_Time            Strm_I  Btch_Ins_I
2014-05-31  200312500   HL03             NULL         1.0000    1.0000         1.0000      2014-06-17 11:10:57.330  1005    24851e0a-53983699-14b4-69109

Select * from helios.dbo.CBA_SRD_Loan where Loan_I in ('200312500') and convert(date, Btch_Time) = '2014-06-17'

回答12:

Convert it back to datetime after converting to date in order to keep same datatime if needed

select Convert(datetime, Convert(date, getdate())  )

回答13:

In PLSQL you can use

to_char(SYSDATE,'dd/mm/yyyy')

回答14:

First Convert the date to float (which displays the numeric), then ROUND the numeric to 0 decimal points, then convert that to datetime.

convert(datetime,round(convert(float,orderdate,101),0) ,101)

回答15:

If you want to return a date type as just a date use

CONVERT(date, SYSDATETIME())

SELECT CONVERT(date,SYSDATETIME())

DECLARE @DateOnly Datetime
SET @DateOnly=CONVERT(date,SYSDATETIME())

回答16:

Try this.

SELECT DATEADD(DD, 0, DATEDIFF(DD, 0, GETDATE()))
