Hi Losing,
You have the usual way to verify if a variable is numeric, and that would be to use a regexp:
unless ($val1=~/\A[-+]?\d+\.?\d*\Z/) {
#quote here $val1, for example:
$val1=$dbh->quote($val1);
}
I'm obviously, assuming that $dbh->quote for a DB2 connection don't quote the values correctly, that I think should happen.

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).

or How to display code and escape characters
are good places to start.
