Assume that you have a list of numeric values mixed with numeric

values appended with characters – like 2a, 12, 5b, 5a, 10, 11, 1, 4b.

Sorting on a list like this would usually end up so:

mysql> SELECT version -> FROM version_sorting -> ORDER BY version; +---------+ | version | +---------+ | 1 | | 10 | | 11 | | 12 | | 2a | | 4b | | 5a | | 5b | +---------+ 8 rows in set (0.03 sec)

To sort the list based on the numeric values, simply do this:

mysql> SELECT version -> FROM version_sorting -> ORDER BY CAST(version AS UNSIGNED), version; +---------+ | version | +---------+ | 1 | | 2a | | 4b | | 5a | | 5b | | 10 | | 11 | | 12 | +---------+ 8 rows in set, 4 warnings (0.00 sec)

That is really cool. Do you know of any way to do it if the reverse is true. So here is my list:

BG1

BG11

BG12

BG13

BG2

BG3

BG4

Do you know how I can order those correctly?

Thanks
