We're organizing our first SQL Saturday event in Dallas on May 22nd, hoping to make it an annual event.  It will be held at the Region 10 Education Center in Richardson, and we currently have 4 tracks slated:  Development, Administration, Business Intelligence and Beginner.  I'm particularly excited about the Beginner track since we so rarely find those at t ...

by tkejser via Microsoft SQL Server Development Customer Advisory Team on 12/14/2009 1:58:36 PM

Author: Thomas Kejser Reviewers: Peter Byrne, Sunil Agarwal, Prem Mehra, Peter Scharlock, Lindsey Allen, Mark Souza As part of your database monitoring, you may be keeping track of the free space in the transaction log. One reason to do this, is to detect a rogue query consuming too much transaction log space. If you have such monitoring set up, you need to be a bit careful about tempdb. Recall that unused space in the transaction log in a FULL and BULK LOGGED recovery mode database is rec ...

Automating UBO

by ErinW via Erin Welker on 11/15/2009 4:14:15 PM

I was preparing for my presentation at PASS and wanted to show some code for automating usage-based optimization.  This is the process that allows for creating aggregation designs based on past query activity.  I was surprised to find that there were no code examples posted on the web on how to do this, at least none that I could find.  BIDSHelper and AggManager have similar functionality but, upon examining the code, they both use a more manual approach of examining each Dataset ...

Selectively using secure connection to SQL Server

by SQL Protocols via SQL Protocols on 10/19/2009 9:48:00 PM

But this setting will force all clients to use encryption and any client that is not able to use an encrypted connection will fail. If you need to connect to SQL Server selectively here is how to achieve this: You can take advantage of the two client settings, “Force Protocol Encryption” and “Trust Server Certificate” and tw ...
