This article discusses about retrieving only the date from a datetime value in SQL Server.
Why Converting Datetime to Date?
There are many times where you might need to only retrieve the date from a datetime value.
For example, you may have today’s datetime (2011-10-10 20:30:28.230) and you want to only get the following value: 2011-10-10.
Using the DATE Datatype in SQL Server 2008 and later
In SQL Server 2008 or later, you can easily do this by casting/converting the datetime value to the datatype DATE.
A typical example is the following:
--Datetime variable declaration DECLARE @dateTimeValue as datetime SET @dateTimeValue=GETDATE() --Cast the datetime value to the DATE datatype SELECT CAST(@dateTimeValue as DATE) as OnlyDate GO
Extract the Date from Datetime in SQL Server Earlier than 2008
However, in earlier versions of SQL Server the DATE type is not available.
So, if you have a SQL Server 2005 instance or earlier and you want to get the date value from a datetime value you can just create and use a simple scalar-valued function like the following:
--------------------------------- -- Create scalar-valued function - --------------------------------- CREATE FUNCTION dateOnly ( @dateInput datetime ) RETURNS varchar (10) AS BEGIN declare @tempRes as varchar(10) declare @tempYear as varchar(4) declare @tempMonth as varchar(2) declare @tempDay as varchar(2) set @tempYear=(select cast ((datepart(yyyy,@dateInput)) as varchar(4))) set @tempMonth=(select cast ((datepart(MM,@dateInput)) as varchar(4))) set @tempDay=(select cast ((datepart(dd,@dateInput)) as varchar(4))) set @tempRes=@tempYear+'-'+@tempMonth+'-'+@tempDay RETURN @tempRes END GO -----------------------------
Now that the function is created, the first example changes to:
--Datetime variable declaration DECLARE @dateTimeValue as datetime SET @dateTimeValue=GETDATE() --Get only the date value by calling the scalar-valued function SELECT dbo.dateOnly(@dateTimeValue) as OnlyDate GO
