In this tutorials i going to explain how to write the custom queries in drupal 7. The most common style of question in Drupal could be a static question. A static question is one which will be passed to the info nearly verbatim.

<?php
  $output = '';
  $result = db_query("SELECT nid FROM {node} WHERE whatever");
  while ($row = db_fetch_object($result)) {
    // Load the node - You can also built the object yourself if you know which fields you need.
    $node = node_load($row->nid);
   // Put a build_mode key on the $node object
    $node->build_mode = 'teaser';
    // Check the teaser flag and show_links flag.
    $teaser = ($node->build_mode != 'full') ? TRUE : FALSE;
    $show_links = ds_show_field('nd', $node->type, $node->build_mode, 'links');
    // Use node_view to render.
    $output .= node_view($node, $teaser, FALSE, $links);
  }
  return $output;
?>

<?php

$output = '';

$result = db_query("SELECT nid FROM {node} WHERE whatever");

while ($row = db_fetch_object($result)) {

// Load the node - You can also built the object yourself if you know which fields you need.

$node = node_load($row->nid);

// Put a build_mode key on the $node object

$node->build_mode = 'teaser';

// Check the teaser flag and show_links flag.

$teaser = ($node->build_mode != 'full') ? TRUE : FALSE;

$show_links = ds_show_field('nd', $node->type, $node->build_mode, 'links');

// Use node_view to render.

$output .= node_view($node, $teaser, FALSE, $links);

}
