CAP_FIRST function gives syntax error - mysql

Question

I found this function for capitalizing the first letter of words in a string, but it is giving me a syntax error on line 8 when I try to run it in SQL in PHPMyadmin. Can anyone help me sort out what the problem is?
Here is the code:
CREATE FUNCTION CAP_FIRST (input VARCHAR(255))
RETURNS VARCHAR(255)
DETERMINISTIC
BEGIN
DECLARE len INT;
DECLARE i INT;
SET len = CHAR_LENGTH(input);
SET input = LOWER(input);
SET i = 0;
WHILE (i < len) DO
IF (MID(input,i,1) = ' ' OR i = 0) THEN
IF (i < len) THEN
SET input = CONCAT(
LEFT(input,i),
UPPER(MID(input,i + 1,1)),
RIGHT(input,len - i - 1)
);
END IF;
END IF;
SET i = i + 1;
END WHILE;
RETURN input;
END;
And this is the error:
MySQL said: Documentation

Answer 1

The delimiter signals the DB engine the end of your statement. Normally it is ;. But that would end the stored procedure at the first ;. And its definition would be incomplete.
You can change the delimiter and add it to the end of your procedure. After that change the delimiter back to ;

CREATE FUNCTION CAP_FIRST (input VARCHAR(255))
