There are three ways to retrieve the current DateTime in SQL SERVER. CURRENT_TIMESTAMP, GETDATE(), {fn NOW()}
CURRENT_TIMESTAMP
CURRENT_TIMESTAMP is a nondeterministic function. Views and expressions that reference this column cannot be indexed. CURRENT_TIMESTAMP can be used to print the current date and time every time that the report is produced.
GETDATE()
GETDATE is a nondeterministic function. Views and expressions that reference this column cannot be indexed. GETDATE can be used to print the current date and time every time that the report is produced.
{fn Now()}
The {fn Now()} is an ODBC canonical function which can be used in T-SQL since the OLE DB provider for SQL Server supports them. {fn Now()} can be used to print the current date and time every time that the report is produced.
If you run following script in Query Analyzer. I will give you the same results. If you see the execution plan there is no performance difference. It is the same for all the three select statements.
SELECT CURRENT_TIMESTAMP
GO
SELECT {fn NOW()}
GO
SELECT GETDATE()
GOPerformance:
There is absolutely no difference in using any of them. As they are absolutely the same.
My Preference:
I like GETDATE(). Why? Why bother when they are the same!!!

I am using (right(CONVERT([char](8),getdate(),(108)),(10))) to get only the time part,however it is not showing the AM,PM part.How can I get the AM,PM part.
Please suggest.
Thank You
Somalia, look at the documentation on CONVERT to see what formats support am/pm. I see 100, 109, 130, and 131.
hi,
I want to fetch todays date from the whole database , not from any particular Table and that is already in database. please help me…!!!

select getdate()
I think GETDATE() works more quckly than {fn Now()}

Hi!
I need a bit of unique help.
Is there any way to retrieve the last updated records (for the last week say) if you DO NOT have the date stored anywhere in your table?
I know this is a dumb question but then again it’s kind of a silly mistake to make when creating the table! N what the hell… it’s worth a shot rite?
Could someone please tell me if they think this is at all remotely possible?
Without date or audit triggers this is not possible
am pretty new to sql queries…
in the below query
‘———————————–
SELECT USERS.USERS_NAME, COMPANY.COMPANY_NAME, LOGS.LOGS_DATETIME, LOGS.LOGS_ACTION
FROM LOGS INNER JOIN
COMPANY ON LOGS.LOGS_COMPANY_ID = COMPANY.COMPANY_ID INNER JOIN
USERS ON LOGS.LOGS_USERS_ID = USERS.USERS_ID
WHERE (LOGS.LOGS_COMPANY_ID = 11) AND (LOGS.LOGS_ACTION LIKE ‘uploaded%’) AND (LOGS.LOGS_DATETIME = GETDATE()) OR
(LOGS.LOGS_ACTION LIKE ‘downloaded%’)
ORDER BY LOGS.LOGS_DATETIME DESC
‘———————————–
—i need to filter records from the log table which as uploaded and downloaded in logs_action field.
this query should be run on the current date and teh cutoff time is 5.30pm for e.g. the query should run for today date and any file uploaded or downloaded before 5.30pm today should be shown.
thanks a ton
Hello,
I am trying to get the number of days between a date span.
If I have a span of three months I would like it to appear like the example down below. I would have the parameter as 01/01/2009 – 03/31/2009, but want the results split out. Can anyone help?
Jan xxhours
Feb xxhours
March xxhours
@Maegen
Look at DATEDIFF() to find the intervals. If you have difficulty, post what you have tried and perhaps we can help.

Hello to everyone
SELECT CONVERT(VARCHAR(10), GETDATE(), 101) AS SystemDate, LEFT(RIGHT(CONVERT(varchar, GETDATE(), 0), 8), 6) + ‘ ‘ + RIGHT(CONVERT(varchar, GETDATE(), 0), 2) AS SystemTime
Just copy the code above to obtain the Date and Time separate in each column the time format is HH:MM AM/PM that will vary in your system time and the date format is MM/DD/YYYY.
Sample Output:
SystemDate SystemTime
07/23/2009 3:59 PM
I hope you find it useful.
God Bless to all :)

Just copy the code above to SQL Query or View to obtain the Date and Time separate in each column the time format is HH:MM AM/PM that will vary in your system time and the date format is MM/DD/YYYY. There’s so many person want to know how will you format time in HH:MM AM/PM now here’s the answer. luckily i find it out. :)

Hi,
I want to create database backup file with current date and time.
For example : database name is : RemoteDatabase
Current Date Time is : 10 August 2009 11:29 AM
How can I give this name to my .bak file?
Or if it is not possible can I provide time only like
RemoteDatabase_11:29AM.bak
Thanks

This is exactly what you needed
Is it possible to put GetDate() or CURRENT_TIMESTAMP as a field’s default value? If yes, when I update a row, will this field update itself with the the timestamp of that update moment?
@Lucas
1. First question, Can Getdate() be used as default value to a column ?
Ans: Yes, GetDate() can be used as a default value for a column.
2. Second Question, when I update a row, will this field update itself ?
Ans: No. It will not update by itself, you will have to update this manually.
Consider below script as example.
create table #Example1 ( Eid Int, Ename varchar(40), Date_Time datetime default (Getdate()))
Insert into #Example1 (Eid, Ename) values ( 1, ‘SQL’ )
Insert into #Example1 (Eid, Ename) values ( 2, ‘SQQ’ )
Select * from #Example1
— Now update statment.
Update #Example1
Set Ename = ‘SQL’
, Date_Time = Getdate() — updating manually.
Where Eid = 2
Select * From #Example1.
Drop table #Example1.
How ever, this could be done automatically as well,
You can have a FOR UPDATE or AFTER UPDATE Trigger created on the table.
This trigger will fire when there is any update on the table, and inside this trigger, you can update your datetime column with the current datetime.
You can also use, if update statement inside trigger, to be specific, mentioning if there is any update for these specific columns only then update date_time column.
I dont suggest using trigger though, if you see many updates on the table. This could decrease your application performance significantly.
