Ah, the joys of database management questions. I'm confident that B and D are the correct answers. ANALYZE doesn't lock the table, and if it's not used, the optimizer might not be able to choose the most efficient plan. Seems pretty straightforward to me.
This question is making my head spin! I think I'll go with C and D. Reducing the file size sounds like a nice bonus, and if ANALYZE is not used, the optimizer might not be able to find the best plan. That's my best guess.
I'm not too sure about E, that seems a bit extreme. If ANALYZE is not used, it doesn't mean you can't see any data at all. I think A and D are the best options here. The statistics need to be updated, and the optimizer needs that information to do its job properly.
Haha, this question is like a database riddle. I'd say B and C are the correct answers. ANALYZE doesn't lock the table, and if you use the FULL option, it can reduce the file size, right? I'm pretty confident about those.
Hmm, I'm a bit uncertain about this one too. But I'm leaning towards A and D. Renewing the statistics seems important, and if ANALYZE is not used, the optimizer might not be able to choose the most efficient plan.
I'm not sure about this question, the options seem a bit confusing. I think I'll go with B and D, as the ANALYZE command is supposed to update the statistics and help the query optimizer choose the best execution plan, but it shouldn't lock the table.
