MySQL Wildcard

Hello All, What I want to do is get all the fields from a table without specifying which ID to grab from. I am trying to implement a wildcard in my query. What am I doing wrong? I keep getting... "Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource" CODE::::: function getOptGrps($ID){

      if ($ID == "All") {
         $ID = "%"; // % = MySQL multi character wildcard
      }
      $q = "SELECT * FROM ".OPT_GRPS_TABLE." WHERE OptGrpID LIKE '$ID' ";
      $result = $this->query($q);
      /* Error occurred, return given name by default */
      if(!$result || (mysql_numrows($result) < 1)){
         return NULL;
      }
      /* Return result array */
      $array_results = mysql_fetch_array($result);
      return $array_results;

} AND this does not work either function getOptGrps(){

      $q = "SELECT * FROM ".OPT_GRPS_TABLE;
      $result = $this->query($q);
      /* Error occurred, return given name by default */
      if(!$result || (mysql_numrows($result) < 1)){
         return NULL;
      }
      /* Return result array */
      $array_results = mysql_fetch_array($result);
      return $array_results;
