Error in the update

In the update of I modulate in the process #3, apparently not this the field or they forgot to erase the field “oid”
error:

user warning: Unknown column 'oid' in 'location' query: ALTER TABLE location CHANGE oid eid int unsigned NOT NULL default '0' in /var/www/html/includes/database.mysql.inc on line 121.

Code:

function location_update_3() {
  $ret = array();

  switch ($GLOBALS['db_type']) {
    case 'mysql':
    case 'mysqli':
      $ret[] = update_sql("ALTER TABLE {location} CHANGE oid eid int unsigned NOT NULL default '0'");
      break;
  }

I think that I would have of being:

function location_update_3() {
  $ret = array();

  switch ($GLOBALS['db_type']) {
    case 'mysql':
    case 'mysqli':
      $ret[] = update_sql("ALTER TABLE {location} CHANGE eid int unsigned NOT NULL default '0'");
      break;
  }
