Which case does InnoDB store database names in?

Solution (By Examveda Team)

This question asks about how InnoDB, a popular storage engine in MySQL, handles database names.

Think of it like this: When you create a database, you give it a name. InnoDB needs to store this name internally to keep track of things. But does it store the name exactly as you typed it, or does it make any changes?

Let's look at the options:
Option A: lower: This means InnoDB would convert your database name to lowercase, no matter what you typed. For example, if you named your database "MyDatabase," InnoDB would store it as "mydatabase."
Option B: upper: This means InnoDB would convert your database name to uppercase. So, "MyDatabase" would become "MYDATABASE."
Option C: mixed: This means InnoDB would keep your database name exactly as you typed it, including any mix of uppercase and lowercase letters. "MyDatabase" would remain "MyDatabase."
Option D: random: This is unlikely. There's no reason for a database system to randomly change the case of your database names.

So, which option is correct? The answer is Option C: mixed. InnoDB stores database names exactly as you enter them, respecting the case of the letters.
