#! perl -w scipt
use strict;
use warnings;
[download]

Good! But then no need for -w.

Actually, -w and use warnings are scoped differently. -w is dynamically scoped (i.e. it's a global), while use warnings is file/block scoped. In other words, -w affects modules, but use warnings only affects the file its in.

"scipt" should not be there, however.

So why not avoiding to use the intermediate variable @files and just do

for (<*.sql>) { # I never use C<foreach> ;-)
[download]

Why load the entire list into memory? Just use:

while (<*.sql>) {
   ...
[download]

---

# I still prefer C<for> orver C<foreach>!!
[download]

I use for for for loops (e.g. for (1..100)) and foreach for foreach loops (e.g. foreach (@array)). Using for unconditionally as you do is bad programming, since it affects the ability to read your program negatively.
