Randy Dyess

I have been working with SQL Server for over 5 years as both a development and production DBA. Before SQL Server I spent time as both a Visual Basic developer and Microsoft Access developer. Numerous projects upsizing Access to SQL Server lead me to become a full-time SQL Server DBA. Currently I have the privilege of working on one of the world's largest SQL Server "read-world" production installations at Verizon Communications for Verizon's billing project. We have 11 main databases totaling over 9 Terabytes of data with the largest single database over 2.2 Terabytes. My current position is as a development DBA, developing
new Transact-SQL code and enhancing existing code. Before working at Verizon, I worked at one of the largest advertising firms in America: Rapp Collins. There I supported up to 60 SQL Server web databases at a time, with some Oracle thrown in, doubling as both a development DBA and production DBA. Clients before Rapp Collins include: Auto One (a leading auto loan lender), Realpage, Inc. (leader in multi-housing management software) and BlueCross BlueShield of Texas (a large insurance company).

Optimizer Join Methods

Understanding the different types of joins used by the optimizer will help developers and DBAs understand how the optimizer is routing their queries. Developers often create queries without knowing that it would only take a few tweaks to produce an execution plan that utilizes one optimizer join method over another. These small tweaks can have dramatic effects on the optimization of the query and the ultimate satisfaction of the query by the end-users.
