I always say, “Never train on live data” because if something happens, it’s a “problem,” to say the least. Today I failed to abide by my own words. Guess what, something happened. The database with 98,542 records shrunk a bit — to 6 records. So did my stomach.
Having never seen this before, I called Tech Support. The rep hadn’t seen it either. He put me on hold and found out a couple of the other reps had heard of this. What did it mean? That the database had crashed and I needed to restore it from a backup. And, of course, the firm didn’t think there was a backup! Fortunately, I found a copy of the database file, and all was well. Of course, I strongly recommended that the firm backup the data — and when I return for more training, we’ll use my training databases.
