REGEXP does not take collation into account.

Solution (By Examveda Team)

This question asks about how MySQL's REGEXP operator works with character sets and collations.

Collations are sets of rules that determine how characters are compared and sorted. They can impact things like case sensitivity and the order of characters.

REGEXP, short for Regular Expressions, is a powerful tool used for pattern matching in strings. It allows you to search for specific patterns within text data.

Now, the question asks if REGEXP considers collation when it performs its pattern matching. The answer is True.

REGEXP does not take collation into account. This means that when you use REGEXP, it matches patterns based on the raw character values, ignoring how those characters would be ordered or compared according to a specific collation.

Let's illustrate with a simple example:
Suppose you have a string "hello world" and you want to search for "hello".
If you use REGEXP, it will find a match even if the string was stored with a collation that treats "h" and "H" as equivalent. REGEXP looks for the exact character sequence "hello", regardless of the collation rules.

In short, when using REGEXP in MySQL, you're dealing with raw character matching, not taking into account any collation settings.
