Automaticaly popluating Current Date in a Db Field

Hi,
I have a field in he db called LogDate. I have made it a timestamp type. Is
there a formula or a default value i can set for this field in the table
design view so that everytime a record is added, this field is automaticalll
y
populated with teh current date?
Thanks

pmudDid youy read anything in the SQL Server documentation about the timestamp
datatype? In spite of its poor name, it has nothing to do with date or
time.
Try the following instead:
CREATE TABLE dbo.MyStuff
(
StuffName NVARCHAR(32) PRIMARY KEY,
CreatedDate SMALLDATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
);
GO
INSERT dbo.MyStuff(StuffName) SELECT N'foo';
WAITFOR DELAY '00:00:01';
INSERT dbo.MyStuff(StuffName) SELECT N'bar';
GO
SELECT StuffName, CreatedDate FROM dbo.MyStuff;
DROP TABLE dbo.MyStuff;

data type is used for concurrency checking using optomistic locking and does
not represent an actual date and time.
I typically use a default value of CURRENT_TIMESTAMP to put the current date
and time in a field.

Thanks for the reply. I made it a datetiem, and in the default value, I used
the function, GetDate() , and it worked. :)

(cross-platform) standard is CURRENT_TIMESTAMP. They are absolutely
equivalent for SQL Server, except using getdate() will provoke the "Wrath of
CELKO" (tm). :)

I had saved my tiable with GetDate() as the default value adn data type as
datetime. Now I changed teh default value to CURRETNT_TIMESTAMP as suggested
by you, but when i click on Save , the default value automatically changes t
o
GetDate() . What do you suggest for this? Can this be a problem?
Thanks

This is Enterprise Manager playing tricks on you. My suggestion is to stop
using Enterprise Manager for these things, use Query Analyzer and learn the
T-SQL equivalent(s).
A|||Ok. Thanks Aaron. I will try through Quey Analyzer.

If you use Enterprise Manager to "verify" be aware that it may still want to
convert CURRENT_TIMESTAMP to GETDATE().
