If you are using Bash shell -

Code:
$
$
$ cat f31
BDG0100.2011091620162100CF5341.DAT
BDG0100.2011091720175500CF5342.DAT
BDG0100.2011091820192900CF5343.DAT
BDG0100.2011091920210600CF5344.DAT
$
$
$ while read line; do echo ${line:8:8}${line: -4}; done < f31
20110916.DAT
20110917.DAT
20110918.DAT
20110919.DAT
$
$

I'm not sure sqlite is the appropriate tool here.

some thing like this might do what you need:
Code:
for i in *.DAT; do
   mv $i $(echo $i | sed 's/^[^.]*\.\([0-9]\{8\}\)[A-Z0-9]*\.DAT/\1.DAT/')
done

Code:
cut > _new_ -c 9-16,31- infile && mv --  _new_ infile
