Select records using WHERE clause on comma delimited field
<p>I have a table myTable with 2 fields (4 example):</p>

<pre><code>ID   Zip_Codes
===  =========
1    60148,60123,61034,61234
2    60122,61034
</code></pre>

<p>I want to use:</p>

<pre><code>$zip = 61034;
$qry = "Select ID from myTable Where $zip in Zip_Codes";
</code></pre>

<p>Is that possible?
What makes it fast?
Other better solution?</p>
