Question

Why does some query that works in mysql doesn’t work with db_query? For instance –

” SELECT * FROM {tb1},{tb2}WHERE {tb1}.vid=%d ” (Of course I substitute %d with actual vid value while I’m testing in mysql environment)

“SELECT f1,f2,…,f10 FROM {tb1} INNER JOIN {tb2} ON {tb1}.vid = {tb2}.vid WHERE {tb1}.vid = %d AND {tb2}.vid = %d

Although I get 1 record returned in mysql environment for both statements, db_query doesn’t return anything at all. Any idea what mistake I’m making? For what is worth, I’m using IIS 7.5, Mysql 5.5, php 5.2.12
****UPDATE**** db_query/db_fetch_object work just fine. It just that hook_view isn’t being invoke. So, as a result, no data is displayed. Sorry for the trouble.

UPDATED

function mymodule_load($node){
   $query = 'SELECT f1,f2,...,f10 FROM {tb1} INNER JOIN {tb2} ON {tb1}.vid = {tb2}.vid WHERE {tb1}.vid = %d AND {tb2}.vid = %d';

   $result = db_query($query,$node->vid);//If I use db_query($query,$node->vid,$node->vid), drupal doesn't invoke hook_view

   drupal_set_message($node->vid,"status"); //for testing purpose
   return db_fetch_object($result);
}

function mymodule_view($node, $teaser = FALSE, $page = FALSE){
    $node = node_prepare($node, $teaser); // get it ready for display

    $f1 = check_markup($node->f1);
     ..............
    $f10 = check_markup($node->f10);

    // Add theme stuff here
    $node->content['mycontent'] = array(
       '#value' => theme('defaultskin', $f1,...,$f10),
       '#weight' => 1,
    );


    return $node;
}

function mymodule_theme(){

    return array(
        'defaultskin' => array(
            'template' => 'node-defaultskin',
            'arguments' => array(               
                'f1' => NULL,
                ......
                'f10' => NULL,
            ),
        ),
    );
}

Have you tried…

db_query(“SELECT f1,f2,…,f10 FROM {tb1} tb1
INNER JOIN {tb2} tb2 ON tb1.vid = tb2.vid
WHERE tb1.vid = %d AND tb2.vid = %d”, $vid, $vid);
