The best is to use the prepare method with placeholders:

my $sth = $dbh->prepare("INSERT INTO whatever VALUES(?, ?, ?, ?, ?, ?,
+ ?, ?, ?, ?, ?, ?, ?, ?)")

while (<INFILE>)   {
      my @line = (parse_csv ($_)); 
      $sth->execute(@line);
}

This has the benefit of taking care of the quoting for you, but also of adding a performance increase, as just having to prepare the query once will save some time, as opposed to the DBI 'do' subroutine, which has to prepare it each time.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
