Database class problem

[Gamemaniak]

Well I just started learning to use classes in PHP. But now I'm running into some problems. I'm using a MySQL Database class and I want to use this one in my News class. It says there is an SQL error when I use 'function query'.

class News

<?php

class News extends Database {
 
 private function getCategory() {
 $returnArray = null;
 
 $qsubcat = $this->query("SELECT
 *
 FROM
 news_subcat");
 
 while($fsubcat = mysql_fetch_array($qsubcat)) {
 $returnArray[] = $fsubcat;
}
 
 return $returnArray;
 }
 
 public function setCategory() {
 $returnStr = null;
 
 $categoryDatasource = $this->setCategory();
 
 if(is_array($categoryDatasource)) {
 
 foreach($categoryDatasource as $categoryArray) {
 $returnStr.= '<option value="'.$categoryArray['subcat_id'].'">'.stripslashes($categoryArray['subcat_name']).'</option>';
 }
 
 return $returnStr;
 }
 
 }
 
}

?>

class Database

function query($sql, $only_first = false)
{
$this->recent_link =& $this->link;
$this->sql =& $sql;
$result = @mysql_query($sql, $this->link) or $this->raise_error();

$this->query_count++;

if ($only_first)
{
$return = $this->fetch_array($result);
$this->free_result($result);
return $return;
}
return $result;
}

Can you post the exact SQL error ?
