I upvoted him even if I don't entirely agree because I think this is a good debate to be had. I tried some of this stuff myself a few months ago, and was surprised that the typical sample SQL injection attacks you see advertised didn't work (on my database and dbd) because it didn't execute multiple statements. What may be different is that, even after noticing that I decided to keep using placeholders, for the same reasons others have cited in this thread.
In other words, I think it's good that the OP tried to figure out how things work, but I think one should be wary of extrapolating this too far and reach the conclusion that SQL injection is "impossible".

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).
