In order to use the example here, you need to create a table,
just execute the following SQL lines using your MySQL client:
---------------------------------------------------------------------

CREATE TABLE `quickdbtest` (
  `catid` int(11) NOT NULL auto_increment,
  `catname` varchar(255) default NULL,
  PRIMARY KEY  (`catid`)
);

insert  into `quickdbtest`(`catid`,`catname`) values (1,'Big'),(2,'Small'),(3,'Average'),(4,'Light'),(5,'Huge');
