Subject [jira] Updated: (DBUTILS-38) example documentation page, update query
Date Sun, 16 Mar 2008 21:43:24 GMT

     [ https://issues.apache.org/jira/browse/DBUTILS-38?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dennis Lundberg updated DBUTILS-38:
-----------------------------------

    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:

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

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

{code}
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);
{code}

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?

{code}
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);
{code}

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