Which mode tells the server to recognize double quote as an identifier quoting character?

Solution (By Examveda Team)

This question asks about a specific mode in MySQL that changes how the database interprets double quotes (").

In MySQL, double quotes can be used for a few different things. They can be used to surround identifiers, like table or column names. They can also be used to enclose string literals, which are just plain text values.

The mode that determines how MySQL handles double quotes is called ANSI_QUOTES. When this mode is enabled, MySQL follows the ANSI SQL standard, and double quotes are specifically recognized as identifier quoting characters. This means that when you use double quotes around a name, MySQL will treat it as a name, even if it contains reserved keywords.

Let's break down the options:

Option A: ANSI_DQ is not a valid mode in MySQL.
Option B: ANSI_QUOTES is the correct answer. This mode tells MySQL to interpret double quotes as identifier quoting characters, adhering to the ANSI SQL standard.
Option C: ANSI_RECG_QUOTES and Option D: ANSI_RECG_DQUOTES are not valid modes in MySQL.

So, the answer is Option B: ANSI_QUOTES.
