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?
