CREATE TRIGGER tr[TableName]LastModifiedDate ON [TableName]
FOR UPDATE 
AS
UPDATE [TableName] SET [TableName].LastModified=getdate()
FROM [TableName] INNER JOIN Inserted ON [TableName].[UniqueID]= Inserted.[UniqueID]

First, create two new fields in your table "Created", and "LastModified" as "datetime" fields, being sure to allow nulls.  Then run this code as a query to create triggers that will update the appropriate field when a record is modified, or a record is inserted.  This proves very useful when you're dealing with a huge database.

In the code below replace [TableName] with your actual table name, and replace [UniqueID] with a unique ID field name in your table.
