audit storeproc

Here is a good storeproc to audit your database tables for changes

first create table for your audit list

****** Object: Table [dbo].[Auditlist] Script Date: 07/12/2012 15:10:35 ******/ ANSI_NULLS ON QUOTED_IDENTIFIER ON ANSI_PADDING ON TABLE [dbo].[Auditlist]([sz30tablename] [varchar]
)(128) NOT NULL ON [PRIMARY]GO
SET
GO
ANSI_PADDING OFF

then insert into this the tables you want to audit

insert into auditlist values ('tablename')

then create the proc

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[sp_addaudittable]') AND type in (N'P', N'PC'))
DROP PROCEDURE [dbo].[sp_addaudittable]
GO
USE [databasename]
GO
/****** Object:  StoredProcedure [dbo].[sp_addaudittable]    Script Date: 07/12/2012 14:46:15 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

GO


then run proc

exec sp_addaudittable 'tablename'

This will create a table tablename_a

it will then print the code to create the triggers, copy this out and run it into the database you now have the triggers for audit.
