Christoffer Hedgate

I work in Lund, Sweden, at a company called Apptus Technologies. Apptus are specialized in database research and consulting, including development of search engines. Most of the time I work with SQL Server as an architect, administrator and developer, but I have also done some work with other DBMS such as Oracle and TimesTen. I also do some programming, mainly in Visual Basic, C# and Java (plus a couple of scripting languages).

I am also the co-owner of sql.nu (http://www.sql.nu/) where you can find more articles from me.

This article will describe a couple of much easier methods of measuring performance of queries.

On the Trail of the ISO Week

Chris Hedgate, one of our regular SQL Server columnists, recently became intrigued by the way that SQL Server implements the week number. His concern was why SQL Server treats week 53 as week 1, which is not that way that ISO6801 sees it. Read about his investigation into the methods of implementing an algorithm to solve this problem.
