<p>is there a way to have a mysql select statement return fully qualified column names like "table.field" without using AS for every single field?</p>
<p>like so:</p>

</code></pre>
<p>and the result would be:
"table1.ID", "table1.name"... | <p>Not really. You could write some dynamic SQL to accomplish this, but it wouldn't be simple. If you really want the dynamic SQL, let me know and I could try to whip something up.</p>
