/********************************************************************
Example file
This example shows how to use the sql_Generator class

The example shows the use of the function makeUpdate()
It updates the name and e-mail field to anonymous if the customer is
under 18 years.

The example is based on the following MySQL table:

CREATE TABLE customer (
  cust_id int(10) unsigned NOT NULL auto_increment,
  name varchar(60) NOT NULL default '',
  email varchar(60) NOT NULL default '',
  age tinyint(3) unsigned NOT NULL default '0',
  date_created datetime NOT NULL default '0000-00-00 00:00:00',
  date_modified datetime NOT NULL default '0000-00-00 00:00:00',
  PRIMARY KEY (cust_id)
) TYPE=MyISAM;
