How to add time to DateTime in SQL
SqlSql Server-2008DatetimeSql Problem Overview
I'm trying to add custom time to datetime in SQL Server 2008 R2.
Following is what I've tried.
SELECT DATEADD(hh, 03, DATEADD(mi, 30, DATEADD(ss, 00, DATEDIFF(dd, 0,GETDATE())))) as Customtime
Using the above query, I'm able to achieve it.
But is there any shorthand method already available to add custom time to datetime?
Sql Solutions
Solution 1 - Sql
Try this
SELECT DATEADD(day, DATEDIFF(day, 0, GETDATE()), '03:30:00')
Solution 2 - Sql
For me, this code looks more explicit:
CAST(@SomeDate AS datetime) + CAST(@SomeTime AS datetime)
Solution 3 - Sql
Try this:
SELECT DATEDIFF(dd, 0,GETDATE()) + CONVERT(DATETIME,'03:30:00.000')
Solution 4 - Sql
Try this
SELECT DATEADD(MINUTE,HOW_MANY_MINUTES,TO_WHICH_TIME)
Here MINUTE is constant which indicates er are going to add/subtract minutes from TO_WHICH_TIME specifier. HOW_MANY_MINUTES is the interval by which we need to add minutes, if it is specified negative, time will be subtracted, else would be added to the TO_WHICH_TIME specifier and TO_WHICH_TIME is the original time to which you are adding MINUTE.
Hope this helps.
Solution 5 - Sql
Or try an alternate method using Time datatype:
DECLARE @MyTime TIME = '03:30:00', @MyDay DATETIME = CAST(GETDATE() AS DATE)
SELECT @MyDay+@MyTime
Solution 6 - Sql
You can do:
SELECT GETDATE()+'03:30:00'
Solution 7 - Sql
You don't need to split the time, case it or any of that stuff. Convert the time to seconds since midnight, then add it to the date. This should work with any version of SQL that supports DATEADD and DATEDIFF.
SELECT DATEADD(SECOND, DATEDIFF(SECOND, '00:00:00', '14:30:00'), '2021-01-01') AS
COMBINED_DATETIME
Solution 8 - Sql
The following is simple and works on SQL Server 2008 (SP3) and up:
PRINT @@VERSION
PRINT GETDATE()
PRINT GETDATE() + '01:00:00'
PRINT CONVERT(datetime,FLOOR(CONVERT(float,GETDATE()))) + '01:00:00'
With output:
Microsoft SQL Server 2008 (SP3) - 10.0.5500.0 (X64)

Solution 9 - Sql
DECLARE @DDate date -- To store the current date
DECLARE @DTime time -- To store the current time
DECLARE @DateTime datetime -- To store the result of the concatenation
;
SET @DDate = GETDATE() -- Getting the current date
SET @DTime = GETDATE() -- Getting the current time
SET @DateTime = CONVERT(datetime, CONVERT(varchar(19), LTRIM(@DDate) + ' ' + LTRIM(@DTime) ));
;
/*
1. LTRIM the date and time do an automatic conversion of both types to string.
2. The inside CONVERT to varchar(19) is needed, because you cannot do a direct conversion to datetime
3. Once the inside conversion is done, the second do the final conversion to datetime.
*/
-- The following select shows the initial variables and the result of the concatenation
SELECT @DDate, @DTime, @DateTime
Solution 10 - Sql
Start Day Time : SELECT DATEADD(day, DATEDIFF(day, 0, GETDATE()), '00:00:00')
End Day Time : SELECT DATEADD(day, DATEDIFF(day, 0, GETDATE()), '23:59:59')
