Pulling last updated record

Recommended Posts

Hi. I am trying to figure out the best approach to pull THE most recent record for display, and ONLY the most recent one. I am really not sure how to go about doing this. Ive just started into stored procedure programming and php, but havent found anything yet on this one. Thanks.

You could create a timestamp column that is set to:

ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

 

Then when you create or update a record the current timestamp will be inserted into that column.  A simple query would then return the result.

$sql = "SELECT * FROM table ORDER BY ts DESC LIMIT 1";
$result = mysql_query($sql);
if(mysql_num_rows($result) > 0) {
  $r = mysql_fetch_assoc($result);
  echo $r['ts'] . ' is the most recent record!';
}

 

PS. I may be wrong, but mysql_insert_id() will not retrieve an auto_increment id from an UPDATE query.
