Answer: Option C
Solution (By Examveda Team)
This question is about how we can check how MySQL plans to execute a query. Imagine you have a task to do, you might plan out the best way to complete it, right? MySQL does the same thing for your queries!The optimizer is like MySQL's planner. It figures out the most efficient way to get the data you want.
So, which statement lets you see this plan? The answer is Option C: EXPLAIN.
Here's why the other options are incorrect:
* Option A: ANALYZE helps you gather statistics about your tables. It's used for optimization, but it doesn't show you the specific plan.
* Option B: VERIFY checks the integrity of your tables, like making sure everything is in the right place.
* Option D: SHOW gives you information about different parts of MySQL, like databases or users. It's not specifically for looking at the optimizer's plan.
So, remember, if you want to understand how MySQL will handle your query, use the EXPLAIN statement!
