In a C# 2010 desktop application, I need to add an audit table to an application that would be similar to the 'main' table. Basically whenever anyting is changed in the 'main' table I need to show the corresponding change in the 'audit' table. The 'audit' table will be a mirror copy of the 'main' table. The only difference is one table is called 'main' table and the other table is called the 'audit' table.
**Note these table reside in a sql server 2008 r2 database.
Would you setup a trigger? If so, can you show me the sql you would use?
Would you write C#.net 2010 code? If so, can you show me the code that would solve my problem?
Let's say you have a table containing customer orders. An order has an ID, a status, and a number of other things including creation date and user. As the order is processed, the status will change and you want to be able to report each status change.
Rather than having one row and overwriting the previous values, you can create a new row with the new values.
In this way you can easily see the details of an order's life all in one table. When a new state is created, the only change you make to the previous state is to set the NextID field. And the current record is the one with NextID==null.
