Description

Hello,

I came across DBUtils:
http://jakarta.apache.org/commons/dbutils/examples.html

and I found your contact email:
http://jakarta.apache.org/commons/dbutils/team-list.html

In this example page, you show how to query a db, and get a bean object:

QueryRunner run = new QueryRunner(dataSource);
ResultSetHandler h = new BeanHandler(Person.class);
Person p = (Person) run.query("SELECT * FROM Person WHERE name=?", "John Doe", h); 

It would be great to show also that it can handle list of objects:

QueryRunner run = new QueryRunner(dataSource);
ResultSetHandler h = new BeanHandler(Person.class);
List list = (List) run.query("SELECT * FROM Person WHERE name=?", "John Doe", h); 
while (Person p : list)
  System.out.println(p);

or something like this.

More importantly, it is not obvious how to execute an update query, using a bean object.
I did not find it in the documentation.
Would it be something like this?

QueryRunner run = new QueryRunner(dataSource);
ResultSetHandler h = new BeanHandler(Person.class);
Person p = (Person) run.query("SELECT * FROM Person WHERE name=?", "John Doe", h); 
p.setName("new name");
run.update("UPDATE Person WHERE name = "John Doe", p);

Could you please add the correct example in your example documentation webpage?
