Reflections on Mistakes in Tech: The Day I Almost Lost It All
In the dynamic world of technology, we often find ourselves navigating uncharted waters, which can lead to both valuable learning experiences and, sometimes, gut-wrenching mistakes. I was recently inspired by a discussion about Azure MFA and began to reflect on a particularly harrowing moment in my tech career that many in the industry can relate to—an experience that certainly made my stomach drop.
Early in my career as an implementation consultant, I was still finding my footing in SQL. One routine day, a client requested some records to be deleted from the database. Armed with the ability to test my code by highlighting specific sections, I felt confident in executing the operation. In a classic case of oversight, I only ran the selection part of my query without applying the necessary conditions in the ‘WHERE’ clause. The unintended result? I ended up deleting millions of records from the production environment during the busiest season of the year.
In such moments, panic set in as sheer terror washed over me—what had I done? Fortunately, we were using Oracle 11g, and just a week before, we had implemented the flashback functionality. This saved us from a potential disaster, enabling us to restore the lost data promptly.
This frightening experience taught me an invaluable lesson about the importance of diligent testing and the need to work within safe environments, particularly when handling critical data. Since then, I’ve committed to ensuring that I always rigorously test my code before making any changes in production–a habit that has served me well in the fast-paced world of technology.
Mistakes are part and parcel of any career, especially in tech. What’s your story? Have you had a similar moment that made you rethink your approach to your work? Let’s share our experiences and learn from one another!

Thank you for sharing your insightful experience. Mistakes like accidentally deleting data can be incredibly stressful, but they also serve as valuable learning opportunities. It’s great to hear that the Oracle 11g flashback feature saved the day; having such Data Recovery options in place is essential when working with critical data in production environments.
To help prevent similar incidents, consider implementing additional safeguards such as:
BEGIN TRANSACTIONandROLLBACKduring testing before committing changes.Moreover, leveraging version control for your SQL scripts and adopting a code review process can further minimize errors. Always validating your queries in a staging environment before executing in production is a best practice.
Thanks again for highlighting the importance of diligent testing and safeguarding critical data. Your experience underscores how crucial it is to have robust recovery mechanisms and cautious workflows in place.
