My company is just starting to look at adding functionality to retain historical data for key tables and columns for auditing purposes in many of our SQL Server databases. I have seen some of your recent tips related to triggers (Forcing Trigger Firing Order in SQL Server and Trigger Alternatives in SQL Server - OUTPUT Clause). Based on using triggers or a similar technology, what is the best way to store the historical data?

It has come to my attention that some of our MSDB databases are getting what I would consider large for a system database. Some of our MSDB databases are over 2 GB which is a little perplexing because I know we do not create any user defined objects in that database. Can you give me some insight into the issue? I know we have this issue with both SQL Server 2000 and 2005 instances.

On my database server I have my databases set to the full recovery model, but the transaction logs get quite big, so I am issuing a BACKUP LOG with NO_LOG. I am not exactly sure if this causes any issues, but I know that I am able to free up space in my transaction log and shrink the file. Is this the correct way to handle this situation?

One of the more obscure requirements that a developer may find themselves facing is the need to compare a row with its immediate sibling. One such case is when a list of values needs to be processed to produce a moving average or to smooth a sequence of statistical numbers where their order is important. For example, values lying along a time line. The solution is actually quite simple, but not immediately obvious.

When you are trying to pin down the cause of a problem with a SQL Server, there is probably going to come a time when you need to get 'trace' information. If you've ever done that, you'll know how easy it is to get overwhelmed by the detail.
