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. Here, Shawn McGehee shows how to get round the problem by capturing trace information on a schedule, filtering the captured information, and monitoring it from a central location.
