It’s been a crazy few weeks. As I mentioned previously, I presented at two SQL Saturday Events in back to back weeks. I’m on the core committee for the North Texas SQL Server User Group SQL Saturday, so I was overwhelmed with things to do and couldn’t stop to blog. So, now that I’ve taken […] I’ll be presenting at two SQL Saturdays back to back. You are taking advantage of SQL Saturday events, right? SQL Saturday Chicago is this weekend (3/26), and I’ll be presenting: Data Warehousing – How to Convince “The Bobs” I got a meeting with the Bobs in a couple of minutes… Building your first Data Warehouse […] “Melodical Murray is a human musical instrument; he makes music by blowing his…blank” – Match Game In the previous article I discussed the issues when working with Null-able fields in Joins and Where clauses. This article will deal with the problems of blank values. What About Blanks?

Note for the non […] All of the queries we’ve looked at so far will return all of the records in a table. This isn’t very efficient. The Where clause filters records out of your result set that you do not want. For example, suppose we’re only interested in Sales Order Master records for “Acme Rockets Inc.” The following select […] I mentioned in my last article that I would be posting a video showing you the basics of working with Toad for SQL Server. What do you think of my first effort? Tweet As I mentioned in the last article, you need to develop or adopt a standardized way of writing T-SQL code. In this article, I’m going to share the habits I’ve developed, “my way” if you will. Vizzini: Finish him. Finish him, your way. “First learn stand, then learn fly. Nature rule, Daniel-san, not mine.” – Karate Kid What is SQL? SQL (Structured Query Language) is a language for manipulating database data and structure.
