Another way for case-insensitive matching is to use a different “collation”.

Is like a comparison operator in SQL?

The reason I specify “ASCII characters” is because, the LIKE operator is case sensitive by default for unicode characters that are beyond the ASCII range.
Can a like operator ignore the character case?
You have an option to define collation order at the time of defining your table. If you define a case-sensitive order, your LIKE operator will behave in a case-sensitive way; if you define a case-insensitive collation order, the LIKE operator will ignore character case as well:
How to get a case sensitive search in SQL?
If you want to achieve a case sensitive search without changing the collation of the column / database / server, you can always use the COLLATE clause, e.g. Works the other way, too, if your column / database / server is case sensitive and you don’t want a case sensitive search, e.g.
