Thanks to the Philly SQL Server User Group (PSSUG) and to everyone who attended SQLSaturday #69 in the City of Brotherly Love yesterday. It was a great event with a lot of great people. My presentations are available for download at the links ...

The Try-N-Save SSIS Packages from my SSIS Dimensional Data Optimization presentation are available at http://cid-8f7e6c950afc6b3e.office.live.com/self.aspx/.Public/Presentation/TryNSave.zip. I'm still working on getting the sample database uploaded - even compressed a backup is larger than SkyDrive's upload filesize limit. I'll script it out when ...

Just finished giving the SSIS High-Performance Dimensional Data Load presentation at SQLSaturday #59 NYC.  Here are the slides in PDF format.  I'll upload the Try-N-Save code and sample data later for attendees to play with. Thanks to everyone who attended my session and thanks to Melissa D. and NJSQL for putting this ...

This month’s T-SQL Tuesday post is about LOB data http://sqlblog.com/blogs/michael_coles/archive/2010/05/03/t-sql-tuesday-006-what-about-blob.aspx.   For this one I decided to post a sample Tiger/Line SQL database I use all the time in live demos. For those who aren't familiar with it, Tiger/Line data is a dataset published by the U.S. ...

Creating SSMS custom ...

This post is my entry for Adam Machanic's T-SQL Tuesday #004, hosted this time by Mike Walsh. I was at the RSA Conference in San Francisco last week discussing database encryption options in SQL Server 2008 and one question seemed to keep coming up. The question concerns FILESTREAM and Transparent Data Encryption (TDE), but first a little ...

Ask about nearly any kind of SQL-based date calculation in the newsgroups, and you'll likely get responses that include use of an auxiliary calendar table.  It's a really good idea, and something I highly recommend to anyone who has to do date-based calculations on the server.  For those who do dimensional modeling, you'll probably ...
