[support] D7 What is the result of hook_field_schema?

[Jeff Greenberg]

When I install a module with the following .install file:

function my_widget_field_schema($field) {
  $columns = array(
    'duration' => array('type' => 'varchar', 'length' => 8, 'not null' =>
FALSE),
  );
  return array(
    'columns' => $columns,
  );
}

What should the impact be on the database tables? I receive no errors, and
watchdog says that the module is installed, and that it is enabled, but I
see no tables added to the db that reflect the field name, widget name, etc.
