"Incidentally, I have never heard of using -T for taint checking. What is that about?"
Firstly, I am not sure how many times I have told you this, if you are going to update a post, it is better indicate in the post what you have changed. So to answer your original question, taint checking is well documented, has been discussed in many articles, it is covered in relevant tutorials and super search returns many hits. So once again, reading the documentation should answer your question.

I don't know what database system you are using. However, I would nea
+rly always recommend holding your SQL within a stored procedure held
+within the database. The stored procedure will not execute unless th
+e variables meet the data types set in the stored procedure. It has
+other added benefits potentially.

Incidentally, I have never heard of using -T for taint checking. What
+ is that about?

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.
