I'm having some issues with my ResultSet using JDBC.
Here's my relation:
create table person (
person_id number(5) generated always as identity
minvalue 1
maxvalue 99999
increment by 1 start with 1
cycle
cache 10,
firstname varchar(10) not null,
lastname varchar(10) not null,
);
I'm trying to insert a (firstname, lastname) into the tuple and then get the person_id that comes out of it. Here's my JDBC code:
//connection is taken care of beforehand and is named con
prep = con.prepareStatement("insert into person (firstname, lastname) values (?, ?)", Statement.RETURN_GENERATED_KEYS);
prep.setString(1, firstname);
prep.setString(2, lastname);
prep.execute();
ResultSet generated = prep.getGeneratedKeys();
if (generated.next()) {
String key = generated.getString("0");
System.out.println(key);
}
This works all fine. But my problem is that the key should be an integer, not a String. Every time I run this, I get a ResultSet that contains a string of "AAA3vaAAGAAAFwbAAG", or something along those lines. I want to get the person_id so I can use it later in my Java program.
Is there something I'm doing wrong in regards to searching through the ResultSet or the execution of the statement itself?
