Assuming you are using mysqli (and not PDO) you can't use a simple query() because you want to execute multiple commands. You will need to use multi_query() in combination with store_result(), more_results() and next_result().

Here is some code I used once:

$db=mysqli_connect($databasehost,$databaseuser,$databasepass,$databasename) or die ("Connection failed!");
$result = $db->multi_query($sql);

if ($err=mysqli_error($db)) { echo $err."
"; }

if ($result) {
  do {
  if ($res = $db->store_result()) {
      echo "";

      // printing table headers
      for($i=0; $i{$field->name}";
      }
      echo "\n";

      // printing table rows
      while($row = $res->fetch_row())
      {
          echo "";
          foreach($row as $cell) {
            if ($cell === NULL) { $cell = '(null)'; }
            echo "";
          }
          echo "\n";
      }
      $res->free();
      echo "
$cell
";

    }
  } while ($db->more_results() && $db->next_result());
}
$db->close();
