CREATE FUNCTION PROPER(inputStr varchar(1500)) 
RETURNS VARCHAR(1500)
DETERMINISTIC
BEGIN
    DECLARE x, y, result VARCHAR(1500);
    SET result = '';
    SET x = '';
    SET y = LOWER(TRIM(inputStr));
    WHILE CHAR_LENGTH(y) > 0 DO
        -- get next word
        SET x = SUBSTRING_INDEX(y, ' ', 1);
        -- set upper case the first char
        SET x = CONCAT(UPPER(SUBSTRING(x, 1, 1)), SUBSTRING(x, 2));
        -- the final s (greek language)               
        IF RIGHT(x,1) = 'σ' THEN
            SET x = CONCAT(left(x, CHAR_LENGTH(x) - 1),'ς');
        END IF;
        -- add word to result
        SET result = CONCAT(result, ' ', x);
        -- prepare y for next loop
        SET y = TRIM(SUBSTRING(y, CHAR_LENGTH(x) + 1));
    END WHILE;
    RETURN (TRIM(result));
END$$
