I am inclined to believe Anonymous Coward in that the EXPORT function is not a SQL command, and thus not available through DBI. I can't get it to work (with DBI) either:

$dbh->do ("export to table_foo of del select id, str from table_foo");

DBD::DB2::db do failed: [IBM][CLI Driver][DB2/LINUXX8664] SQL0104N  
An unexpected token "export to table_foo of del select id," 
was found following "BEGIN-OF-STATEMENT".  
Expected tokens may include:  "<revoke>".  SQLSTATE=42601

However, DB2::Admin works for me (Linux x86_64, DB2 Express-C V.9.5.0, perl v5.10.0):

use strict;
use DB2::Admin;

# use 'perl -s'
our $INST;
our $USER;
our $PASS;
our $TABL;
our $SCHM;

DB2::Admin::->SetOptions('RaiseError' => 1);
DB2::Admin::->Connect(
  'Database' => $INST,
  'Userid'   => $USER,
  'Password' => $PASS
);

DB2::Admin->Export(
  'Database'   => $INST,
  'Schema'     => $SCHM,
  'Table'      => $TABL,
  'OutputFile' => "/tmp/data-$SCHM-$TABL.del",
  'FileType'   => 'DEL'
);
__END__

Running:

$ perl -ws admin.pl -INST=TEST -USER=db2inst1 -PASS=***** -SCHM=db2ins
+t1 -TABL=table_foo
$ cat /tmp/data-db2inst1-table_foo.del 
1,"foo"
2,"bar"
3,"tze"
