Natural Sort in MySQL

Is there an elegant way to have performant, natural sorting in a MySQL database?

For example if I have this data set:

• Final Fantasy
• Final Fantasy 4
• Final Fantasy 10
• Final Fantasy 12
• Final Fantasy 12: Chains of Promathia
• Final Fantasy Adventure
• Final Fantasy Origins
• Final Fantasy Tactics

Any other elegant solution than to split up the games' names into their components

• Title: "Final Fantasy"
• Number: "12"
• Subtitle: "Chains of Promathia"

to make sure that they come out in the right order? (10 after 4, not before 2).

Doing so is a pain in the a** because every now and then there's another game that breaks that mechanism of parsing the game title (e.g. "Warhammer 40,000", "James Bond 007")

Here is a quick solution:

SELECT alphanumeric, 
       integer
FROM sorting_test
ORDER BY LENGTH(alphanumeric), alphanumeric

Just found this:

SELECT names FROM your_table ORDER BY games + 0 ASC

Does a natural sort when the numbers are at the front, might work for middle as well.

Same function as posted by @plalx, but rewritten to MySQL:

DROP FUNCTION IF EXISTS `udf_FirstNumberPos`;
DELIMITER ;;
CREATE FUNCTION `udf_FirstNumberPos` (`instring` varchar(4000)) 
RETURNS int
LANGUAGE SQL
DETERMINISTIC
NO SQL
SQL SECURITY INVOKER
BEGIN
    DECLARE position int;
    DECLARE tmp_position int;
    SET position = 5000;
    SET tmp_position = LOCATE('0', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF; 
    SET tmp_position = LOCATE('1', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF;
    SET tmp_position = LOCATE('2', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF;
    SET tmp_position = LOCATE('3', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF;
    SET tmp_position = LOCATE('4', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF;
    SET tmp_position = LOCATE('5', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF;
    SET tmp_position = LOCATE('6', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF;
    SET tmp_position = LOCATE('7', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF;
    SET tmp_position = LOCATE('8', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF;
    SET tmp_position = LOCATE('9', instring); IF (tmp_position > 0 AND tmp_position < position) THEN SET position = tmp_position; END IF;

    IF (position = 5000) THEN RETURN 0; END IF;
    RETURN position;
END

DROP FUNCTION IF EXISTS `udf_NaturalSortFormat`;

CREATE FUNCTION `udf_NaturalSortFormat` (`instring` varchar(4000), `numberLength` int, `sameOrderChars` char(50))

    WHILE (i <= sameOrderCharsLen) DO
        SET sortString = REPLACE(sortString, SUBSTRING(sameOrderChars, i, 1), ' ');
        SET i = i + 1;
    END WHILE;

    WHILE (numStartIndex <> 0) DO
        SET numStartIndex = numStartIndex + numEndIndex;
        SET numEndIndex = numStartIndex;

        WHILE (udf_FirstNumberPos(SUBSTRING(instring, numEndIndex, 1)) = 1) DO
            SET numEndIndex = numEndIndex + 1;
        END WHILE;

        SET numEndIndex = numEndIndex - 1;

        SET padLength = numberLength - (numEndIndex + 1 - numStartIndex);

        IF padLength < 0 THEN
            SET padLength = 0;
        END IF;

        SET sortString = INSERT(sortString, numStartIndex + totalPadLength, 0, REPEAT('0', padLength));

        SET totalPadLength = totalPadLength + padLength;
        SET numStartIndex = udf_FirstNumberPos(RIGHT(instring, CHAR_LENGTH(instring) - numEndIndex));
    END WHILE;

    RETURN sortString;
END

Usage:

SELECT name FROM products ORDER BY udf_NaturalSortFormat(name, 10, ".")

I think this is why a lot of things are sorted by release date.

A solution could be to create another column in your table for the "SortKey". This could be a sanitized version of the title which conforms to a pattern you create for easy sorting or a counter.
