it depends on what you need to achieve, but a good place to start would be
something like:
while (my $line = <FILE>)
{
$dbh->do ('INSERT INTO table (line) VALUES (?)', undef, $line);
}
Where FILE is your open filehandle, and $dbh is your DBI connection, and
you've modified the SQL as necessary.
If performance is an issue, you may want to try this (although the
performance gains depend on database you're using)
my $st = $dbh->prepare ('INSERT INTO table (line) VALUES (?)');
while (my $line = <FILE>)
{
$st->execute ($line);
}
