Hello,
I have a Database of µChips and I want to sort it "case insensitive" and
in "numerical order" in the same time.
Since the name of the µChips are mostly [:alpha:][:num:]* I am running
into problems since the first one can have 0-5 characters.
So, what I need is to get the substring (leading [:alpha:]) unify and
sort it and not use a loop over it, and get all chips from the category.
Now from each category cut the [:alpha:], the sort numerical and after
this re-add the cuted [:alpha:].
Hmmmm, first I am searching a solution the get the "Categories", which
mean, the leading [:alpha:] AND, if numerical "categories" exist, there
first number.
The listing should be something like
3
8
AW
AT
DS
ICL
LM
MAX
W
Does somone has a solution for it? (I do not like to reinvent the wheel)
Thanks, Greetings and nice Day/Evening

if it's from a database could you "order by substring(columnname, 2,1)"
or similar..?
