Learning from Heart-Stopping Mistakes in the Tech Industry
In the fast-paced world of technology, the potential for mistakes is often high, especially for professionals who are still navigating their early careers. Inspired by a recent discussion on multi-factor authentication challenges in Azure, I find it a great time to reflect on our experiences and the lessons learned along the way.
One moment that stands out for me occurred during my tenure as an implementation consultant when I was still honing my SQL skills. Tasked with deleting records at the client’s request, I was utilizing our Integrated Services Environment (ISE) which had a feature allowing you to run highlighted code only. However, in a moment of oversight, I inadvertently executed a select statement without the accompanying criteria to restrict the records. This unfortunate error resulted in the deletion of millions of records in our production environment right in the middle of a critical busy season.
Fortunately, we were using Oracle 11g at the time and had just implemented the Flashback feature, which provided a lifeline during this crisis. With the assistance of Flashback, we were able to recover the lost data, but the experience served as a stark reminder of the importance of rigor in testing environments before applying changes to live systems.
Since that incident, my team and I have resolved to prioritize rigorous testing in controlled environments to prevent any similar disasters. This experience is a testament to the importance of diligence and humility in our profession. We are all learning and growing, and sharing these stories can help others avoid making the same mistakes.
