Off to go look for code.

Hmm... found and modified this for columns. Is there a cleaner way to do it?

PHP Code:

$query = $vbulletin->db->query("SHOW COLUMNS FROM " . TABLE_PREFIX . "table LIKE 'column'") or die(mysql_error());

if (mysql_num_rows($query) == 0) { insert column } 


And for rows in a table:

PHP Code:

$query = $vbulletin->db->query("SELECT * FROM  " . TABLE_PREFIX . "table LIMIT 1") or die(mysql_error()); 

if (mysql_num_rows($query) == 0) {   add rows } 


Make sense?
