How can I correctly insert data containing special characters into a database field using Perl and DBI?

I have a form, not unlike the post question/comment on this site that I want to post to a field in a database.

However if someone where to put special characters such as @#开发者_运维问答;"| either fails or does not insert correctly. Is there a way to insert said data into a database without Perl trying to treat certain characters as operators?

You could use the quote database handle method. To quote the documentation:

quote

$sql = $dbh->quote($value);
$sql = $dbh->quote($value, $data_type);

Quote a string literal for use as a literal value in an SQL statement, by escaping any special characters (such as quotation marks) contained within the string and adding the required type of outer quotation marks.

$sql = sprintf "SELECT foo FROM bar WHERE baz = %s", $dbh->quote("Don't");

A better practice is to use placeholders and bind values though:

$dbh->do("INSERT INTO foo VALUES(?)", undef, "@#;|");
