Time for another episode of the SQL Friday, The Best SQL Server Links Of The Past Week show.
Here is what I found interesting this past week in SQL Land:
Understanding backups and log-related Trace Flags in SQL Server 2000/2005 and 2008
Kimberly Tripp is giving a play by play from 2000 to 2005/2008 to discuss the differences and what's changed and why those changes were significant. The biggest changes were between 2000 and 2005.

Who is Active? v7.30
Adam Machanic has released the latest version of his Who is Active script. Who is Active? is a comprehensive DMV-based monitoring script, designed to tell you at a glance what processes are active on your SQL Server and what they're up to. It has a number of optional features so that you can get results quickly, or monitor deeply, depending on your needs when you happen to be using the script.
Sp_indexinfo has been updated
Tibor Karaszi has updated his Sp_indexinfo procedure
This procedure will give you the following info:
- What indexes exists for a particular table or for each table in the database
- Clustered, non-clustered or heap
- Columns in the index
- Included columns in the index
- Unique or nonunique
- Number rows in the table
- Space usage
- How frequently the indexes has been used
- Any obvious indexes I should add?

Estimated and Actual execution plan revisited
Gail Shaw explains why the terms ‘estimated execution plan’ and ‘actual execution plan’ are perhaps a little bit misleading.
