If the text and numeric portions of the key are indeed separated by an
underscore, the following should work as an ORDER clause (untested).
ORDER BY substr(TheKeyColumn,1,instr(TheKeyColumn,'_')-1)
ASC,CAST(substr(TheKeyColumn,instr(theKeyColumn,'_')+1) AS INTEGER) ASC
If there are a fixed
I have keys that get generated such as
someKey_1
someKey_2
I just hit the snag that someKey_10 comes between the two of these.
Is there a clean way to get SQLite (in memory) to ORDER these numerically
without having to recode to force leading zeros?

Dr. Richard E. Hawkins,
You can do this.
on mouseUp
-- my field has sample data based on your example
put field myfieldWithData into tData
sort lines of tData ascending numeric by numberTag(each)
-- tData now contains your sorted keys, do with them as you wish.
end mouseUp
function numberTag pVar
-- returns the
oh duh. Ignore me. My answer sorts them after the fact with lc. Peters
answer does the same basic thing inside sqlite.

If there are a fixed number of chars before the numeric part of the key,
then you can replace
Let me know if it works. I might have the wrong number of prans, etc but
the theory should work.
