Thanks to everyone who attended my ''Sell Yourself!'' presentation at SQLSaturday #61 in Washington, D.C., and thanks to NOVA SQL for setting up the event! I'm uploading the presentation deck here in PDF, original length, with new materials (I had to cut some slides out due to time limits).  This deck includes a new section on ...

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 ...

Margarity Kerns recently published a very nice article at SQL Server Central on using hash functions to detect changes in rows during the data warehouse load ETL process.  On the discussion page for the article I noticed a lot of the same old arguments against using hash functions to detect change.  After having this same discussion ...

Creating SSMS custom ...

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 ...

Based on feedback from the community (https://connect.microsoft.com/SQLServer/feedback/details/522123/sql-server-2008-service-pack-2 and https://connect.microsoft.com/SQLServer/feedback/details/522122/service-pack-4-for-sql-server-2005), Microsoft has announced plans to release Service Pack 2 for SQL Server 2008 and Service Pack 4 for SQL ...

SQL Server has several aggregate functions like SUM for summation. Summation is the addition of a set of numbers, and it's represented with sigma ...
