The Heart-Stopping Moment: Learning from a Tech Career Blunder

In a fast-paced tech environment, even experienced professionals can find themselves facing moments of sheer panic. A recent discussion about mishaps in tech inspired me to share a particularly jaw-dropping experience early in my career that serves as an important lesson.

During my days as an implementation consultant, I was still getting to grips with SQL queries. My task involved writing a statement to delete records at the request of a client. Our Integrated Software Environment (ISE) had a handy feature that allowed us to test our code by highlighting the status we wanted to run – or so I thought.

I ran a SELECT query but inadvertently executed the delete command without including the necessary WHERE clause. The result? Millions of records vanished from the production environment during our busiest period. It was a gut-wrenching moment that left me reeling.

Fortunately, we were utilizing Oracle 11g at that time, which had just introduced flashback functionality. This feature proved to be a lifesaver, allowing us to restore the deleted records. After that incident, we made it a strict policy to work only in test environments before deploying any code to production.

This experience taught me the critical importance of double-checking and verifying every action I take, especially when working with production data. It’s a reminder that in tech, mistakes can happen in the blink of an eye, but it’s how we learn from them that truly defines our careers.
