Nicolas,
Not sure when the "replace" function was introduced into mysql, but I
think it might do...
REPLACE() exists in 3.23.
Use "replace" in your order by, replacing a-z with null chars, leaving
just your numeric digits, then order by

Hello.
The "brute force" way is to create and UDF or store function which can
extract the numeric part from the string and ORDER BY the results of

A client of mine sells motorcycle parts and the motorcycle models are
for instance:
YZ85
YZ125
WRF450
YZF450
Etc...
If you know motorcycles, you know that the number is always the
displacement in cc.
What I am looking to do here is make it so that the models are sorted
properly according to the
11 matches
