drupal 7 db_query example

Example of db_query in Drupal 7

Here is an example of using the db_query function in Drupal 7:

$query = db_query("SELECT nid, title FROM {node} WHERE type = :type", array(':type' => 'article'));

foreach ($query as $row) {
  // Do something with the results
  $nid = $row->nid;
  $title = $row->title;

In this example, we are using the db_query function to execute a SELECT query on the node table. We are retrieving the nid and title fields from nodes of type "article". The results are then looped through using a foreach loop, and you can perform further actions with each row of data retrieved.

Please note that the table name is enclosed in curly braces {} and the query uses placeholders (:type) to prevent SQL injection. The placeholders are then replaced with the actual values using the array passed as the second argument to db_query.

I hope this example helps! Let me know if you have any further questions.
