CREATE TRIGGER logChanges
ON RepInfo
FOR UPDATE
AS
DECLARE @.RepInfoID INT
IF COLUMNS_UPDATED() > 0
UPDATE RepInfo
SET LastChangedDate = GetDate()
WHERE @.RepInfoID = RepInfoID
GO
--
Trying to update LastChangedDate in a given record when any of the columns
in the record are modified. The first time I ran this, I did not have any of
the "@.RepInfoID" clauses, and I go the whole column to update to GETDATE();
I
didn't want that, so I threw in the references to RepInfoID since it's the
identity column, trying to mimic some VB.NET code I have in another
application. No joy. This has to be a simple fix, but one that's elusive to
me. Any help is appreciated!

Thanks,

Try this:

ON RepInfo
FOR UPDATE
AS
- -- Assuming Columns_Updated() is a user-defined function
IF COLUMNS_UPDATED() > 0
UPDATE RepInfo
SET LastChangedDate = GetDate()
FROM inserted as i

Btw, IF (COLUMNS_UPDATED()) is not a user-defined function. Here's a clip
from SQL Server Books Online:
--<Snip>--
IF (COLUMNS_UPDATED())
Tests, in an INSERT or UPDATE trigger only, whether the mentioned column or
columns were inserted or updated. COLUMNS_UPDATED returns a varbinary bit
pattern that indicates which columns in the table were inserted or updated.
