The Most Terrifying Experience of My Tech Career: A Lesson in Caution

In the fast-paced world of technology, mistakes can happen in the blink of an eye. Reflecting on my journey, one experience stands out as a stark reminder of the importance of diligence and caution.

During my early days as an implementation consultant, I was still finding my footing with SQL. Tasked with executing a client’s request to delete specific records, I took advantage of a feature in our Integrated Software Environment (ISE) that allowed me to test code by highlighting it. Unfortunately, in my haste, I ran the SELECT statement while neglecting the WHERE clause. In an instant, millions of records were deleted from our production environment—in the midst of a busy season, no less.

Fortunately, we were using Oracle 11g at the time and had just implemented the flashback functionality. This feature proved invaluable, allowing us to restore lost data with relative ease. Nevertheless, the incident served as a powerful lesson. From that moment on, I made it a priority to always test my code in a safe environment before executing anything in production.

This experience underscores a vital lesson for anyone in the tech industry: never underestimate the power of caution and double-checking your work. It’s easy to get caught up in the whirlwind of deadlines and projects, but a moment’s haste can lead to catastrophic outcomes. Prioritize your testing procedures and always, always verify before you execute. The peace of mind it provides is well worth the effort.
