lower case 'b' is converted into the word 'node' in the SQL query

I'm not sure if this is the right place to post this but I'm sure I'll be corrected soon enough.

I have a problem with a view where if I enter a term into an exposed filter for the CCK field Full Name (where it only searches the last name BTW) it throws an error if the string begins with a lower case `b`. This doesn't happen with any other letter or with an upper case `B`. The error message, when I use the string `bingo` looks like this:

    * user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'node'ingo%')))' at line 1 query: SELECT count(node.nid) FROM node node LEFT JOIN content_type_person node_data_field_fullname ON node.vid = node_data_field_fullname.vid WHERE (node.status = '1') AND (node.type IN ('person')) AND ((UPPER(node_data_field_fullname.field_fullname_last) LIKE UPPER(''node'ingo%'))) in /home/lucita7/public_html/bis/includes/database.mysql.inc on line 172.

    * user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'node'ingo%'))) ORDER BY node_data_field_fullname_field_fullname_last ASC LIMIT ' at line 1 query: SELECT node.nid, node_data_field_fullname.field_fullname_last AS node_data_field_fullname_field_fullname_last FROM node node LEFT JOIN content_type_person node_data_field_fullname ON node.vid = node_data_field_fullname.vid WHERE (node.status = '1') AND (node.type IN ('person')) AND ((UPPER(node_data_field_fullname.field_fullname_last) LIKE UPPER(''node'ingo%'))) ORDER BY node_data_field_fullname_field_fullname_last ASC LIMIT 0, 15 in /home/lucita7/public_html/bis/includes/database.mysql.inc on line 172.

As you can see it converts `b` into `'node'` (with the single quotes) like this...

(UPPER(node_data_field_fullname.field_fullname_last) LIKE UPPER(''node'ingo%')

The export of the view reads thus...

  $view->name = 'person_list';

  $view->access = array (

  $view->view_args_php = '';

    ),
  );
  $view->requires = array(node_data_field_fullname, node, term_node_13);
  $views[$view->name] = $view;

Many thanks in advance...
