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!!!

If you want default datetime to be added, omit that column during insertion
insert into employee (emp_id,emp_name) (01,’happy’);

Very wrong. You said yourself, getdate() is a nondeterministic function and cannot be indexed in views.
It makes a big difference in views with large tables, where you use the date in a where clause to filter for a reporting date.
SELECT {fn NOW()}
is the one you should choose, and getdate() is the one you should avoid.
But this is very wrong.
You wrote yourself:
GETDATE is a nondeterministic function. Views and expressions that reference this column cannot be indexed.
So if you have a view with a few joins, how do you think getdate() will influence the performance. I can tell you: getdate()’s performance is so very bad, you are a lot faster using the canonic ODBC escape sequence functions, such as fn now() …

I have a Sql Sever 2008 DB with a list of dates and events associated with those dates. I’d like to return only those events that are happening on the current date.
Something like
SELECT [event] FROM [new database] WHERE ([date] = @currentdate) ..I know this isn’t right.
Any advise would be appreciated
