CHAR_LENGTH vs CHARACTER_LENGTH (any difference)

Question

CHAR_LENGTH Returns the length of a string (in characters)

CHARACTER_LENGTH Returns the length of a string (in characters)

I was looking through the SQL string function on w3sch and I saw this, the description is the same.

Is there any difference between them at all?

Answer 1

They are synonyms and do the same thing.
