The Terrifying Missteps of an Emerging Tech Professional

As professionals in the tech industry, we often find ourselves navigating a landscape rife with challenges and pitfalls. Mistakes can occur at any point, and sometimes they leave a lasting impact. One horrendous moment I encountered early in my career still sends chills down my spine—an event that has since become a cautionary tale for me and others in tech.

During my tenure as an implementation consultant, I was still honing my skills with SQL. One day, I was tasked with executing a client-requested deletion of certain records from our database. Our Integrated Security Environment (ISE) offered a nifty feature that allowed me to test SQL statements by highlighting the specific code section I intended to run. Sounds straightforward, right? Unfortunately, a hasty mistake led to catastrophic results.

Instead of only highlighting the desired records for deletion, I inadvertently ran a broader SELECT statement without the necessary WHERE clause. The consequence? Millions of records were lost in production, and this incident occurred during a particularly busy season.

Fortunately, luck was on my side. At that time, we were utilizing Oracle 11g, which had just rolled out the flashback functionality. This feature allowed us to recover the lost data swiftly. Still, the experience was a stark reminder of the importance of diligence and precaution in our work.

Since that day, I have made it a point to always validate my code in test environments before executing any changes in production. This experience has not only shaped my approach to SQL but has also instilled a deeper respect for the integrity of data.
