Note that you should be extremely careful when accepting user data like this; always use Taint mode and launder user input very carefully. See the discussion in Ch 23 of Camel 3rd Ed. 'Detecting and Laundering Tainted Data'.
Secondly, whenever you need to process SQL in a loop like this, consider using the prepare/execute idiom:
my $sth = $dbh->prepare(<<SQL)
INSERT INTO needed_details (quantity,item_number)
VALUES (?,?)
SQL
# Error-check here.
foreach my $quantity (@quantity) {
$sth->execute($quantity,$item_number);
# Error check here.
}
At the very least, this will save you the need to explicitly quote your data; if you envisage inserting many rows in a given program execute, this will save you the cost of the DBMS re-compiling the query on every pass (for those DBMSs that support query preparing).

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).
