Is getdate() the same as CURRENT_TIMESTAMP in a query?

There are not real queries: ItemDate is a datetime column

SELECT * FROM Items WHERE ItemDate > CURRENT_TIMESTAMP
SELECT * FROM Items WHERE ItemDate > getdate()

Also, if you have a DateTime field, can you set it's default to be CURRENT_TIMESTAMP? Or should you use getdate() as it's default value?

I am understand the difference between the datetime column type and the timestamp column type, but I was wondering about the CURRENT_TIMESTAMP variable and if you can use it the same as getdate() in calculations etc.

u can also create a table that uses CURRENT_TIMESTAMP as a DEFAULT constraint

there is an example in the above link on how to create one....
Hi,

Both are same, only thing is many of they are familiar with getdate() than CURRENT_TIMESTAMP. On seeing the CURRENT_TIMESTAMP many have to confusion, whether it wld give only the Timestamp (without date). So U can be clear, just check this example taken from http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tsqlref/ts_cr-cz_60mo.asp page,

Use CURRENT_TIMESTAMP as a DEFAULT constraint
This example creates a table that uses CURRENT_TIMESTAMP as a DEFAULT constraint for the sales_date column of a sales row.

USE pubs
GO
CREATE TABLE sales2
(
 sales_id int IDENTITY(10000, 1) NOT NULL,
 cust_id  int NOT NULL,
 sales_date datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
 sales_amt money NOT NULL,
 delivery_date datetime NOT NULL DEFAULT DATEADD(dd, 10, GETDATE())
)
GO
INSERT sales2 (cust_id, sales_amt)
   VALUES (20000, 550)

This query selects all information from the sales2 table.

USE pubs
GO
SELECT *
FROM sales2
GO

Here is the result set:

sales_id    cust_id    sales_date          sales_amt delivery_date              
----------- ---------- ------------------- --------- -------------------
10000       20000      Mar 4 1998 10:06AM  550.00    Mar 14 1998 10:06AM

(1 row(s) affected)
