First and Last ID of a table

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have a table where I need to figure out the very first ID and the very last ID, so here is what I wrote:

$first_query = "SELECT id FROM mytable ORDER BY id LIMIT 1";
$first_result = mysql_query($first_query,$con);
$first_id = mysql_result($first_result,0,'id');

$last_query = "SELECT id FROM mytable ORDER BY id DESC LIMIT 1";
$last_result = mysql_query($last_query,$con);
$last_id = mysql_result($last_result,0,'id');

I'm just wondering if there was any way to do this more efficiently, like with one query instead of two. Or is this about as simple as I can do it?

Thanks.
