Logging Table Activity

Zone: MS SQL Server

Tags: trigger, column, app_name

I need to log as much information as possible when "unapproved" changes are made to specific tables within a database. I want to log any insert/update/delete activity that doesn't originate from an approved application to a separate table. My current plan is to utilize the host_name, app_name, and user_name functions within triggers to determine the source and if appropriate record the occurence. Does anyone out there have an example of some efficient code to accomplish this? If possible I would also like to record the column updated and the original and updated values (obviously for updates only).

Below is a proposed table structure for direction though you shouldn't feel constrained by this.

CREATE TABLE [tabActivityLog] (
      [LogKey] [int] IDENTITY (1, 1) NOT NULL ,
      [ActivityType] [varchar] (10) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
      [Object] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
      [ObjectID] [int] NULL ,
      [LogDate] [datetime] NOT NULL ,
      [AppName] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
      [HostName] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
      [UserName] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]

ActivityType: one of three values -- 'DELETE', 'UPDATE', 'INSERT'
Object the table being altered
ObjectID the identity value of the field being altered

The rest should be fairly self-explanatory

I am offering 500 pts because although this may be a simple copy and paste for someone out there it will save me a good deal of time. I also am fully aware of how much time and effort the experts donate to this site (besides I have unlimited points to distribute ;-)
