hook_views_pre_execute not work in views 6.x-3.x (yes in 6.x-2.x)

the hook_views_pre_execute(&$view) used for create/change the view's sql not work with view vers 6.x-3.x while work with 6.x-2.x
the function is called but the code for change the sql not work (isn't called)

function nameofyourmodule_views_pre_execute(&$view) {
drupal_set_message($view->name);
//if($view->name=="groups_list2") {
$view->build_info['query']="SELECT node.nid AS nid FROM node";
//$view->build_info['query']="SELECT node.nid AS nid FROM node LIMIT 2";
//} 
 }

I noticed that in views\includes\view.inc
in 6.x-2 there is this code (row 695):

// Let modules modify the view just prior to executing it.
foreach (module_implements('views_pre_execute') as $module) {
$function = $module . '_views_pre_execute';
$function($this);
}

$query = db_rewrite_sql($this->build_info['query'], $this->base_table, $this->base_field, array('view' => &$this));
$count_query = db_rewrite_sql($this->build_info['count_query'], $this->base_table, $this->base_field, array('view' => &$this));

$args = $this->build_info['query_args'];

vpr($query);

while in 6.x-3.x ther is only this (row 825):

// Let modules modify the view just prior to executing it.
foreach (module_implements('views_pre_execute') as $module) {
$function = $module . '_views_pre_execute';
$function($this);
}

in 6.x-2 there is more code; I also add this code in 6.x-3 but problem remain
