You can't. SQL is not a procedural language. You can, however, do it like this:

my $ins="insert into tbl(col) values(:CHK)"; my $sth->prepare($ins);
while(<>) {

     chomp;
     my @arr=split /,/;
     foreach my $chunk (@arr) {
	$sth->bind_param(":CHK",$chunk);
	$sth->execute();
     }	
     $db->commit();

If you decide to do it in Perl, be aware that DBD::Oracle is junk which doesn't support anything to improve performance with the large files. No array interface, no direct load, nada. It's good for hacking but it isn't a serious tool. Currently, there isn't much hope that DBD::Oracle will ever become anything more then a mere toy.
