because the perl script will run in cygwin as a bat file

Cygwin is a compatibility library. You can have cygwin builds of programs, but you can't run in cygwin. Do you mean in bash?

But bash can't process batch files, and I strongly doubt that anyone has made a cygwin build of a batch file interpreter, so that makes no sense.

So let's start over.

You're starting perl from two different shells. A cygwin build of bash (which you referred to as the command line), and the cmd Windows shell (which interpreted your batch file).

There's some difference between the two (PATH? PERL5LIB?), and the easiest way to find out what it is to run perl -V (that's an uppercase "V") from bash ("the command line") and from a batch file.

Could you please post those results and the output of the following command (run from a batch file): 

perl -le"use DBI; print $INC{'DBI.pm'}"

I suspect you have two installations of Perl. One from before you installed Cygwin (which has DBI installed), and a cygwin build of Perl (which doesn't). Differences in the PATH of the two environments affect which installation is being used.
