I would guess that at least half of the programmers where I work would have failed. I wonder how competent developers are at other companies with their SQL databases? I can tell you that as a production DBA when I'm brought in regarding a performance issue, the stuff that I see makes me wonder how some people remain employed as programmers. Full table scans on 50M row table, no problem. Query the database 10,000 times because you don't want to run one query and parse the results, no problem. I just want to scream sometimes!!!
