The Stomach-Dropping Mistakes That Shape Our Tech Careers

In the fast-paced world of technology, we all face moments that make our hearts race and our stomachs drop. These experiences often become crucial learning opportunities that can shape our careers. A recent discussion about Azure’s Multi-Factor Authentication brought to mind one of my most significant blunders during my early days as an implementation consultant.

While I was still getting acquainted with SQL, I was tasked with deleting specific records at a client’s request. The Integrated Service Environment (ISE) I was using provided a way to test code by highlighting parts of it, a feature I thought would keep things safe. In my haste, I ran a SELECT statement but neglected to apply any WHERE clauses to limit the results. The end result? I inadvertently wiped millions of records from our production database—right in the middle of the busy season.

Fortunately, we were using Oracle 11g at the time, which had recently introduced the flashback functionality. This breakthrough feature allowed us to restore the lost data relatively quickly, sparing us from a disaster of major proportions. However, that incident served as a stark reminder of the importance of rigorous testing and adapting to safeguards.

Since that fateful day, I’ve learned to prioritize work in test environments whenever possible and to approach database changes with a level of caution that reflects the consequences of such mistakes. While the tech field is filled with challenges, it’s often the hard lessons that resonate most deeply and lead to professional growth.
