Instructor Details

Hello my name is Kris. I m here because I am passionate about helping non-techie people to overcome their fear of learning SQL. Let Me Help you Get Started on the Right Foot! I know what it is like to not know where to start or whether the time spent learning is worth the effort. That is why I am here to help you to: Get started in an easy to follow step-by-step manner. Use your time wisely so you focus on what is important to learn to get the most value from your time. Answer your questions. Really! Just post a comment and I ll respond. I m here to help. It wasn t long ago that I was helping a colleague with some reporting. She didn t know where to start and soon got overwhelmed and lost as she didn t know SQL. I felt really bad, as she was under pressure to get some summary information to her boss, the built-in reports were falling short, and to make them better would require her to know SQL. At that time that seemed impossible! It in dawned on me, it doesn t have to be that way. Then I discovered a way for anyone with the desire to easily learn SQL. I worked with my co-worker, started to teach her what I learned and soon she was able to write reports and answer her boss questions without getting stressed or ploughing hours into manipulating data in Excel. It hasn t always been easy. Sometimes the information seems abstract or too conceptual. In this case I ve found out that a visual explanation is best. I really like to use diagrams or videos to explain hard-to-grasp ideas. Having video, pictures, and text really help to reinforce the point and enable learning. I know that you want to: be confident writing SQL understand more complicated topics such as joins and sub-queries become fluent in database terms and concepts understand query optimization and performance tuning start your path to become a DBA Through my conversation style, easy to understand lessons, videos, and info-graphics, I ll help you to do this an more. It will take action on your part, but I'm here to help you along the way! So How Did I Become Such A Geek? My journey to SQL starts when back in 1979 when I was in a freshman in High School. Back then I was really interested in computers and joined a Computer Explorer s post hosted by Dow Chemical. We met once a week at the office and got to work on their mini-computers. It was awesome! I learned how to program and really took an interest to it. So much so, that I took my savings and bought a early home computer (Radio Shack TRS-80 Model I). It didn t do much, as it only had 16K of memory, but it was enough for me to learn programming. We ll that was over thirty years ago and I ve loved them ever since. In college I studied computer engineering at University of Michigan (go blue!). I got to learn hardware and software design. One class I really found fascinating was my database theory class. We studied relational database theory and it was great. Before this class I didn t know about databases and every time we wanted to work with data, we would have to write huge programs to do so. Once I learned about databases I realize how powerful they were. We ll I kept at it and now some twenty five years later, I m ready to share my experiences with you.

    This is the knowledge I needed to modify this existing legacy scripts at work, which has complex nested correlated subqueries and derived tables. I just wish there was a tool out there to easily breakdown and visualize the scripts. Thanks again.

    Good course. I’m picking up some SQL tricks from it, which is what I was hoping to do. (Unit 14 needs a little editing. 🙂 )
