RE: How do I add "Date of Birth" to the below query so that I can pull the Date of Birth when I run the query?

You are welcome.  Just paying it back for all the help I got from this forum when I started using Toad.  Just wait until you start using Toad Automation (greatest feature of Toad IMHO), there are tutorial videos online to help you get started.
