MySQL order by string with numbers

Question

I have strings such as M1 M3 M4 M14 M30 M40 etc (really any int 2-3 digits after a letter) When I do \" ORDER BY name \" this returns:

M1, M14, M3

Answer 1

I couldn't get this working for my issue which was sorting MLS Numbers like below:

V12345 V1000000 V92832

The problem was V1000000 wasn't being valued higher than the rest even though it's bigger.

Using this solved my problem:

ORDER BY CAST(SUBSTR(col_name FROM 2) AS UNSIGNED) DESC

Just removed the SUBSTR(col_name FROM 1 FOR 1)
