Which server mode value disables use of built in function names as identifiers?

Solution (By Examveda Team)

This question is about MySQL's server modes, which control how MySQL behaves. Imagine these modes as different settings you can adjust to change how your database works.

One important server mode is related to identifiers. Identifiers are names we give to things in a database, like table names, column names, or even functions.

The question asks about a server mode that prevents you from using names that are already used by built-in functions. For example, if you have a function called "SUM" (which adds numbers), you can't use "SUM" as a table name or a column name.

Let's look at the options:

A) ANSI: This mode makes MySQL follow the standards of the American National Standards Institute, which are rules for how databases should work. It's a general mode, not specifically focused on identifier names.
B) IGNORE_FUNC: This mode is exactly what we are looking for! It disables the use of built-in function names as identifiers.
C) TRADITIONAL: This mode activates a bunch of settings to make MySQL more like older versions, but it doesn't specifically address identifier names.
D) IGNORE_SPACE: This mode allows you to use spaces in your identifiers, but it's not related to the issue of built-in function names.

Therefore, the correct answer is Option B: IGNORE_FUNC

Remember, you can enable or disable server modes in MySQL. This gives you more control over how your database functions and prevents you from accidentally using names that could clash with existing functions.
