Primary key from inserted row jdbc?

Copied from my code:

pInsertOid = connection.prepareStatement(INSERT_OID_SQL, Statement.RETURN_GENERATED_KEYS);

where pInsertOid is a prepared statement.

you can then obtain the key:

// fill in the prepared statement and
pInsertOid.executeUpdate();
ResultSet rs = pInsertOid.getGeneratedKeys();
if (rs.next()) {
  int newId = rs.getInt(1);
  oid.setId(newId);
}

Hope this gives you a good starting point.
