In a previous article, I discussed Merge statement basics. However, in extensive testing I’ve come to realize that my article, like most articles I’ve read about Merge leaves out or mis-handles several important aspects. Rather than edit that article, I’ve decided to publish a series of articles which I hope will clear up some of [...]

For those who don’t know, I’m currently the Data Warehouse Architect for a large scale and complex multi-tenant data warehousing project. Fortunately, the project is being created in SQL Server 2012 and I thrilled to be using the new features. Let me preface this blog post by admitting that my experience with using the SSIS [...] I’m in for a busy week as I have back to back presentations this Wednesday and Thursday nights. On Wednesday the 20th, the Forth Worth SQL Server User Group has asked me to present one of my favorites. I’m constantly revising this presentation as I encounter as I come across new mistakes to share. So, [...] Every time I attend SQL Saturdays I am re-energized, and SQL Saturday 163 BI Edition was no different. This one was particularly special because of my precon presentation, “Data Warehousing In a Day”. I just love getting up in front of a group and teaching and it’s obvious when to the attendees. If all of [...] The T-Sql Merge statement, introduced in SQL 2008, is powerful, versatile, and performant. However, it is also one of T-SQL’s least understood statements.

One of my readers pointed out that he uses the date datatype, rather than using the smart integer key method, when working with SQL 2008+ databases. The [...] Every Kimball Group book I’ve read, as well as every Data Warehouse class I’ve attended, has indicated that a Date Dimension Primary Key should be a smart integer key in the format YYYYMMDD (20110518) so I’ve always built my Date tables that way. However, Barnaby (Blog/Twitter) pointed out that I should be using a Date [...] This Wednesday I’ll be presenting at the Fort Worth SQL Server User Group. Come see me present: Data Warehousing – How to Convince “The Bobs” I got a meeting with the Bobs in a couple of minutes… Building your first Data Warehouse is a long, and often difficult process. How can you get your boss to [...] |
