I have a query that I wrote some time ago looking something like this:
$script = 'SELECT foo FROM bar WHERE item1 = ' . $item1;
if(defined($item2)) { $script .= ' and item2 = ' . $item2; }
if(defined($item3)) { $script .= ' and item3 = ' . $item3; }

Having some time lately to go revisit this (and being smart enough these days to want to do better), I would like to something more like this:
$script = 'SELECT foo FROM bar WHERE item1 = ?';
if(defined($item2)) { $script .= ' and item2 = ?';
if(defined($item3)) { $script .= ' and item2 = ?';

[download]
so that I could do something like this:
$sql->execute($item1,$item2,$item3);

Does DBI support this kind of behavior? Can I pass additional items to execute() even if there are no placeholders that correspond with them? How will DBI react if those items are undefined? SuperSearch yielded nothing, and I couldn't find what I was looking for in the DBI reference. While the DBI docs that you can't pass an undef value to a SELECT statement via a placeholder and expect to get the results you are looking for (that just strikes me as poor programming and a bad idea anyhow), that's not exactly the same as what I'm trying to accomplish.

Any insight is truly appreciated.

Thanks in advance,
MrCromeDome
